2. Wiring Precautions
!! Caution
• Do not leave wire remnants in the instrument, as they could cause a fire and/or a malfunction. • Use a solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the WIL-102-ECH. • Tighten the terminal screw using the specified torque. If excessive force is applied to the screw when tightening, the terminal screw may be damaged. • This instrument does not have a built-in power switch, circuit breaker and fuse. It is necessary to install a power switch, circuit breaker and fuse near the instrument. (Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A) • For a 24 V AC/DC power source, do not confuse polarity when using direct current (DC). • Do not apply a commercial power source to the sensor which is connected to the input terminal nor allow the power source to come into contact with the sensor. • Use the 4-electrode Conductivity Sensor in accordance with the sensor input specifications of the WIL-102-ECH. • Keep the input wires and power lines separate. Note about the 4-Electrode Conductivity Sensor Cable The 4-electrode Conductivity Sensor cable is a highly-insulated (electrical) cable. Please handle it with utmost care as follows. • Do not allow terminals and socket of the 4-electrode Conductivity Sensor cable to come in contact with moisture or oil of any kind. Likewise, ensure fingers are clean, otherwise the insulation will deteriorate, resulting in unstable indication. Be sure to keep the cable dry and clean at all times. If the cable is stained, clean it with alcohol, and dry it completely. • For calibration or electrode checking/replacement, the 4-electrode Conductivity Sensor cable should be wired with sufficient length. • Keep the 4-electrode Conductivity Sensor cable and junction cable away from electrical devices, such as motors or their power lines from which inductive interference emanates.

• Wiring Example Using a Communication Converter IF-400
Shield Wire
Be sure to ground only one end of the shield wire so that current cannot flow to the shield wire. If both ends of the shield wire are grounded, the circuit will be closed, resulting in a ground loop. This may cause noise. Be sure to ground the FG. Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted pair cable.)
Terminator (Terminal Resistor)
The terminator is mounted at the end of the wire when connecting multiple peripheral devices to a personal computer. The terminator prevents signal reflection and disturbance. Do not connect a terminator to the communication line because each WIL-102-ECH has built-in pull-up and pull-down resistors. Communication converter IF-400 (sold separately) has a built-in terminal resistor.

8. Setup
Before using this instrument, setup should be performed to suit the conditions of usage: Setting the Cell constant correction value, Measurement unit, A11, A12, A21 and A22 types, Temperature compensation method, Communication, A□□ output when input errors occur, etc. Setup can be conducted in the Conductivity Input Group, Temperature Input Group and Basic Function Group. If the user's specification is the same as the factory default value of the WIL-102-ECH, or if setup has already been completed, it is not necessary to set up the instrument. Proceed to Section “9. Calibration (p.39)".
8.1 Turn the Power Supply ON.
For approximately 4 seconds after the power is switched ON, the input characters are indicated on the Conductivity Display and Temperature Display. See (Table. 8.1-1).
During this time, all outputs are in OFF status, and LED indicators except the PWR Indicator turn off. After that, measurement starts, indicating the item selected in [Display selection (p.34)]. This status is called Conductivity/Temperature Display Mode.
8.2 Conductivity Input Group

• Conductivity Input Error Alarm
Conductivity input error alarm is used for detecting actuator trouble. Even if Conductivity input error alarm time has elapsed – if conductivity input does not become higher than conductivity input error alarm band – the instrument assumes that actuator trouble has occurred, and sets Status flag 2. In Serial communication, status can be read by reading Status flag 2 (A1, A2 conductivity input error alarm output flag bit). Conductivity input error alarm is disabled during Conductivity Zero or Span adjustment. Conductivity input error alarm is enabled only whenよこと(Conductivity input low limit action) or E c _ H  (Conductivity input high limit action) is selected in [A11, A12, A21, A22 type (pp.22, 23)].
9. Calibration
Conductivity calibration mode, Temperature calibration mode, and Transmission output 1 and 2 adjustment modes are described below.
9.1 Conductivity Calibration Mode
Deterioration of the 4-electrode Conductivity Sensor might cause the cell constant to change. To correct the changed cell constant, conductivity calibration must be performed. Calibrate Conductivity Zero adjustment first, followed by Conductivity Span adjustment. During conductivity calibration, A□□ action is forced OFF. However, ifじるこ！ (Lock 1),じるこ(Lock 2) orじるこう(Lock 3) is selected in [Set value lock (p.31)], the unit cannot move to Conductivity calibration mode. The following outlines the procedure for conductivity calibration. ① When selecting bEFH (Last value HOLD) in [Transmission output 1 status when calibrating (p.33)] or [Transmission output 2 status when calibrating (p.33)], select it while the 4-electrode Conductivity Sensor is being immersed in the solution currently measured. ② Do not immerse the 4-electrode Conductivity Sensor in the standard solution. ③ Press and hold the   key and   key (in that order) together for 3 seconds in Conductivity/ Temperature Display Mode.
④ Set the Conductivity Zero adjustment value with the        or                 key so that the conductivity becomes 0. If conductivity is 0, this adjustment is not necessary. Setting range of the Conductivity Zero adjustment value differs depending on the measurement range. See (Table 9.1-1.). (p. 40) However, it is effective within the measurement range regardless of the Conductivity Zero adjustment value.
⑤ Press the ￼ key. Conductivity Zero adjustment value will be registered, and the unit will move to Conductivity calibration Span adjustment mode. The following is indicated in Conductivity calibration Span adjustment mode.
© Immerse the 4-electrode Conductivity Sensor in the standard solution. ⑦ Set the Conductivity Span adjustment value with the        or Conductivity multiplied by the Span adjustment value is displayed. Conductivity Span adjustment value: 0.700 to 1.300 ⑧ Press the  🌸 key. Conductivity Span adjustment value will be registered, and the unit will revert to Conductivity/ Temperature Display Mode.
9.2 Temperature Calibration Mode
To calibrate a temperature, set a temperature calibration value. If oFF[] (No temperature compensation) is selected in [Temperature compensation method (p.30)], Temperature calibration mode is not available. The unit cannot enter Temperature calibration mode in the following cases: • Whenじるこ！ (Lock 1),じること(Lock 2) orじるこう(Lock 3) is selected in [Set value lock (p.31)]. When a sensor cannot be set at the exact location where measurement is desired, the resulting measured temperature may deviate from the temperature in the desired location. In this case, the desired temperature can be set for the desired location by setting a temperature calibration value. However, it is effective within the input rated range regardless of the temperature calibration value. Temperature after calibration = Current temperature + (Temperature calibration value) (e.g.) When current temperature is 23.5°C, If temperature calibration value is set to 1.5℃: 23.5 + (1.5) = 25.0℃ If temperature calibration value is set to -1.5℃: 23.5 + (-1.5) = 22.0℃ The following outlines the procedure for temperature calibration. ① Press and hold the  ☁ key and  ☁ key (in that order) together for 3 seconds in Conductivity/ Temperature Display Mode.
② Set a temperature calibration value with the Setting range: -10.0 to 10.0℃ ③ Press the ￼ key. Temperature calibration is complete, and the unit reverts to Conductivity/Temperature Display Mode.
9.3 Transmission Output 1 Adjustment Mode
Fine adjustment of Transmission output 1 is performed. WIL-102-ECH is adjusted at the factory, however, differences may occur between the indication value of the connected equipment (recorders, etc.) and output value of this instrument. In this case, perform Transmission output 1 Zero and Span adjustments. Transmission output 1 adjustment mode is available when Transmission output 1 (TA option) or Transmission output 2 (TA2 option) is ordered. The unit cannot enter Transmission output 1 Zero adjustment mode in the following cases: • During Conductivity Zero or Span adjustment, or temperature calibration • Whenじるこ！ (Lock 1),じること(Lock 2) orじるこう(Lock 3) is selected in [Set value lock (p.31)] The following outlines the procedure for Transmission output 1 adjustment. ① Press and hold the  △ key and  ￼ key (in that order) together for 3 seconds in Conductivity/Temperature Display Mode. The unit enters Transmission output 1 Zero adjustment mode, and indicates the following.

Setting range:  ±5.00% of Transmission output 1 span ③ Press the 🌸🌸 key. The unit enters Transmission output 1 Span adjustment mode, and indicates the following.
④ Set a Transmission output 1 Span adjustment value with the      or         key, while viewing the value indicated on the connected equipment (recorders, etc.). Setting range:  ±5.00% of Transmission output 1 span ⑤ Press the      key. The unit reverts to Transmission output 1 Zero adjustment mode. Repeat steps  ② to  ⑤ if necessary. ⑥ To finish Transmission output 1 adjustment, press the ￼ key in Transmission output 1 Span adjustment mode. The unit reverts to Conductivity/Temperature Display Mode.
9.4 Transmission Output 2 Adjustment Mode
Fine adjustment of Transmission output 2 is performed. WIL-102-ECH is adjusted at the factory, however, differences may occur between the indication value of the connected equipment (recorders, etc.) and output value of this instrument. In this case, perform Transmission output 2 Zero and Span adjustments. Transmission output 2 adjustment mode is available only when Transmission output 2 (TA2 option) is ordered. The unit cannot enter Transmission output 2 Zero adjustment mode in the following cases: • During Conductivity Zero or Span adjustment, or temperature calibration • Whenじるこ！ (Lock 1),じること(Lock 2) orじるこう(Lock 3) is selected in [Set value lock (p.31)] The following outlines the procedure for Transmission output 2 adjustment. ① Press and hold the Conductivity/Temperature Display Mode. The unit enters Transmission output 2 Zero adjustment mode, and indicates the following.
② Set a Transmission output 2 Zero adjustment value with the       or          key, while viewing the value indicated on the connected equipment (recorders, etc.). Setting range:  ±5.00% of Transmission output 2 span ③ Press the 🌸🌸 key.
④ Set a Transmission output 2 Span adjustment value with the      or         key, while viewing the value indicated on the connected equipment (recorders, etc.). Setting range:  ±5.00% of Transmission output 2 span ⑤ Press the      key. The unit reverts to Transmission output 2 Zero adjustment mode. Repeat steps  ② to  ⑤ if necessary. ⑥ To finish Transmission output 2 adjustment, press the ￼ key in Transmission output 2 Span adjustment mode. The unit reverts to Conductivity/Temperature Display Mode.
10. Measurement
10.1 Starting Measurement After mounting to the control panel, wiring, setup and calibration are complete, turn the power to the instrument ON. For approximately 4 seconds after the power is switched ON, the input characters are indicated on the Conductivity Display and Temperature Display. See (Table 10.1-1).
(*) This input temperature specification was specified at the time of ordering. During this time, all outputs are in OFF status, and the LED indicators except PWR Indicator are unlit. Measurement will then start, indicating the item selected in [Display selection (p.34)].
10.2 A🇮🇳🇳 Output
When Ec L (Conductivity input low limit action), Ec L H (Conductivity input high limit action), Г元Р ៤ (Temperature input low limit action), or Г元Р Н (Temperature input high limit action) is selected in [A11, A12, A21, A22 type (pp. 22, 23)], the A□□ output is turned ON if the measured value exceeds or drops below the A🌸🌸 value. When EcHL (Conductivity input High/Low limits independent action), 「三HL (Temperature input High/Low limits independent action) is selected in [A11, A12, A21, A22 type (pp. 22, 23)], the A□□ output is turned ON if the measured value exceeds the A□□ High/Low limits independent action upper side span, or drops below the lower side span. A1 or A2 output is turned ON depending on the selection in [A1/A2 output allocation (p.35)] and in [Output ON time/OFF time when A1/A2 output is ON (pp. 35, 36)]. If Output ON time and OFF time are set, A1 or A2 output can be turned ON/OFF in a configured cycle when A1 or A2 output is ON. (Fig. 10.2-1) A□□ output status can be read by reading Status flag 1 (A11, A12, A21, A22 output flag bit) in Serial communication. A□□□ output status, when input errors occur, differs depending on the selection in [A□□] output when input errors occur (p.29)]. • If oFF[] (Disabled) is selected, A[[] output and A[[] output status will be turned OFF when input errors occur. • If on […] (Enabled) is selected, A […] output and A […] output status will be maintained when input errors occur.
10.3 Conductivity Input Error Alarm
Conductivity input error alarm is used for detecting actuator trouble. Even if conductivity input error alarm time (pp. 37, 38) has elapsed, and if conductivity input does not become higher than conductivity input error alarm band (pp. 37, 38), the unit assumes that actuator trouble has occurred, and writes Status flag 2. In Serial communication, status can be read by reading Status flag 2 (A1, A2 conductivity input error alarm output flag bit). Conductivity input error alarm is disabled during Conductivity Zero or Span adjustment. Conductivity input error alarm is enabled only whenよっこ(Conductivity input low limit action) or E c _ H  (Conductivity input high limit action) is selected in [A11, A12, A21, A22 type (pp.22, 23)].

11.3 Communication Procedure
Communication starts with command transmission from the host computer (hereafter Master) and ends with the response of the WIL-102-ECH (hereafter Slave). • Response with Data When the master sends the reading command, the slave responds with the corresponding set value or current status. • Acknowledgement When the master sends the setting command, the slave responds by sending acknowledgement after the processing is terminated. • Negative Acknowledgement When the master sends a non-existent command or value out of the setting range, the slave returns a negative acknowledgement. • No Response The slave will not respond to the master in the following cases: • Global address (Shinko protocol) is set. • Broadcast address (MODBUS protocol) is set. • Communication error (framing error, parity error) • Checksum error (Shinko protocol), LRC discrepancy (MODBUS ASCII mode), CRC-16 discrepancy (MODBUS RTU mode) Master Side (Take note while programming) When the master starts transmission through the RS-485 communication line, the master is arranged so as to provide an idle status (mark status) transmission period of 1 or more characters before sending the command to ensure synchronization on the receiving side. Set the program so that the master can disconnect the transmitter from the communication line within a 1-character transmission period after sending the command in preparation for reception of the response from the slave. To avoid collision of transmissions between the master and the slave, send the next command after carefully checking that the master has received the response. If a response to the command is not returned due to communication errors, set the Retry Processing to send the command again. (It is recommended to execute Retry twice or more.) When the slave starts transmission through the RS-485 communication line, the slave is arranged so as to provide an idle status (mark status) transmission period of 1 or more characters before sending the response to ensure synchronization on the receiving side. The slave is arranged so as to disconnect the transmitter from the communication line within a 1-character transmission period after sending the response. Shinko protocol is composed of ASCII. Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters. Start bit:   1 bit Data format Data bit:   7 bits Parity: Even Stop bit:   1 bit Error detection: Checksum All commands are composed of ASCII. The data (set value, decimal number) is represented by hexadecimal numbers. The negative numbers are represented in 2's complement. Numerals written below the command represent number of characters.

Setting command, Reading command: STX (02H) fixed Response with data, Acknowledgement: ACK (06H) fixed Negative acknowledgement: NAK (15H) fixed Instrument Number (Address): Numbers by which the master discerns each slave. Instrument numbers 0 to 94 and Global address 95. ASCII codes (20H to 7FH) are used by adding 20H to instrument numbers 0 to 95 (00H to 5FH). 95 (7FH) is called Global address, which is used when the same command is sent to all the slaves connected. However, the response is not returned. Sub Address: 20H fixed Command Type : Code to discern Setting command (50H) and Reading command (20H).
Checksum is used to detect receiving errors in the command or data. Set the program for the master side as well to calculate the checksum of the response data from the slaves so that communication errors can be checked. The ASCII code (hexadecimal) corresponding to the characters which range from the address to that before the checksum is converted to binary notation, and the total value is calculated. The lower one byte of the total value is converted to 2's complement, and then to hexadecimal numbers, that is, ASCII code for the checksum. • 1’s complement: Reverse each binary bit. 0 will become 1 and vice versa. • 2’s complement: Add 1 to 1’s complement. A11 value: 1.00 (0064H) Address (instrument number) : 0 (20H) 11.5.1 Transmission Mode There are 2 transmission modes (ASCII and RTU) in MODBUS protocol. Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters. Start bit:  1 bit Data format Data bit:  7 bits (8 bits) (Selectable) Parity: Even (No parity, Odd) (Selectable) Stop bit:   1 bit (2 bits) (Selectable) Error detection : LRC (Longitudinal Redundancy Check) 8-bit binary data in command is transmitted as it is. Data format   Start bit:  1 bit Data bit:  8 bits Parity: No parity (Even, Odd) (Selectable) Stop bit:  1 bit (2 bits) (Selectable) Error detection: CRC-16 (Cyclic Redundancy Check) Max.1 second of interval between ASCII mode characters Communication speed 9600 bps, 19200 bps: To transmit continuously, an interval between characters which consist of one message, must be within 1.5-character transmission times. Communication speed 38400 bps: To transmit continuously, an interval between characters which consist of one message, must be within 750  μs. If an interval lasts longer than 1.5-character transmission times or 750 µs, the WIL-102-ECH assumes that transmission from the master is finished, which results in a communication error, and will not return a response. ASCII mode message is configured to start by Header [: (colon)(3AH)] and end by Delimiter [CR
Communication speed 9600 bps, 19200 bps: RTU mode is configured to start after idle time is processed for more than 3.5-character transmissions, and end after idle time is processed for more than 3.5-character transmissions. Communication speed 38400 bps: RTU mode is configured to start after idle time is processed for
Slave address is an individual instrument number on the slave side, and is set within the range 0 to 95 (00H to 5FH). The master identifies slaves by the slave address of the requested message. The slave informs the master which slave is responding to the master by placing its own address in the response message. Slave address 00H (Broadcast address) can identify all the slaves connected. However, slaves do not respond. The function code is the command code for the slave to undertake the following action types.
Function code is used to discern whether the response is normal (acknowledgement) or if any error (negative acknowledgement) has occurred when the slave returns the response message to the master. When acknowledgement is returned, the slave simply returns the original function code. When negative acknowledgement is returned, the MSB of the original function code is set as 1 for the response. (For example, when the master sends request message setting 10H to the function code by mistake, slave returns 90H by setting the MSB to 1, because the former is an illegal function.) For negative acknowledgement, the exception codes below (Table 11.5.3-2) are set to the data of the response message, and returned to the master in order to inform it of what kind of error has occurred.
Data differs depending on the function code. A request message from the master is composed of data item, amount of data and setting data. A response message from the slave is composed of the byte count, data and exception codes in negative acknowledgements, corresponding to the request message. Effective range of data is -32768 to 32767 (8000H to 7FFFH). After calculating LRC (Longitudinal Redundancy Check) from the slave address to the end of data, the calculated 8-bit data is converted to two ASCII characters, and are appended to the end of message. ① Create a message in RTU mode. ② Add all the values from the slave address to the end of data. This is assumed as X. ③ Make a complement for X (bit reverse). This is assumed as X. ④ Add a value of 1 to X. This is assumed as X. ⑤ Set X as an LRC to the end of the message. ⑥ Convert the whole message to ASCII characters. After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of the data, the calculated 16-bit data is appended to the end of message in sequence from low order to high order. In the CRC-16 system, the information is divided by the polynomial series. The remainder is added to the end of the information and transmitted. The generation of a polynomial series is as follows. (Generation of polynomial series: X 16 + X 15 + X 2 + 1) ① Initialize the CRC-16 data (assumed as X) (FFFH). ② Calculate exclusive OR (XOR) with the 1st data and X. This is assumed as X. ③ Shift X one bit to the right. This is assumed as X. ④ When a carry is generated as a result of the shift, XOR is calculated by X of  ③  and the fixed value (A001H). This is assumed as X. If a carry is not generated, go to step ⑤. ⑤ Repeat steps  ③ and  ④ until shifting 8 times. ⑥ XOR is calculated with the next data and X. This is assumed as X. ⑦ Repeat steps  ③ to  ⑤. ⑧ Repeat steps  ③ to  ⑤ up to the final data. ⑨  Set X as CRC-16 to the end of message in sequence from low order to high order. Numerals written below the command represent the number of characters. ① Reading [Slave address 1, Data item 0080H (Conductivity)] • A request message from the master
• Response message from the slave in normal status [1.00 mS/cm (0064H)] The response byte count means the byte count of the data which has been read. It is fixed as (30H 32H).
• Response message from the slave in exception (error) status (When a data item is incorrect) The function code MSB is set to 1 for the response message in exception (error) status (83H).
• A request message from the master [When A11 value is set to 1.00 (0064H)]
• Response message from the slave in normal status
• Response message from the slave in exception (error) status (When a value out of the setting range is set)
The function code MSB is set to 1 for the response message in exception (error) status (86H). Numerals written below the command represent the number of characters. ① Reading [Slave address 1, Data item 0080H (Conductivity)] • A request message from the master
• Response message from the slave in normal status [1.00 mS/cm (0064H)] The response byte count means the byte count of the data which has been read.
• Response message from the slave in exception (error) status (When data item is incorrect). The function code MSB is set to 1 for the response message in exception (error) status (83H). The exception code (02H: Non-existent data address) is returned (error).
② Setting [Slave address 1, Data item 0006H (A11 value)] • A request message from the master [When A11 value is set to 1.00 (0064H)]
• Response message from the slave in exception (error) status (When a value out of the setting range is set) The function code MSB is set to 1 for the response message in exception (error) status (86H). The exception code (03H: Value out of the setting range) is returned (error).
11.6.1 Notes about Setting/Reading Command • The data (set value, decimal) is converted to hexadecimal numbers. A negative number is represented in 2's complement. • When connecting multiple slaves, the address (instrument number) must not be duplicated. • Data item 0200H to 0209H (User save area 1 to 10) can be read or set in 1 word units. Effective range of data is -32768 to 32767 (8000H to 7FFFH). • MODBUS protocol uses Holding Register addresses. The Holding Register addresses are created as follows. A Shinko command data item is converted to decimal number, and the offset of 40001 is added. The result is the Holding Register address. Using Data item 0001H (Sensor cell constant) as an example: Data item in the sending message is 0001H, however, MODBUS protocol Holding Register address is 40002 (1 + 40001). • Even if options are not ordered, setting or reading via software communication will be possible. Command contents of the A11, A12, A21, A22 will function, however, Transmission output 1 and 2 command contents will not function. • Up to 1,000,000 (one million) entries can be stored in non-volatile IC memory. If the number of settings exceeds the limit, the data will not be saved. So, ensure the set values are not frequently changed via software communication. (If a value set via software communication is the same as the value before the setting, the value will not be written in non-volatile IC memory.) • Be sure to select Lock 3 when changing the set value frequently via software communication. If Lock 3 is selected, all set values – except Sensor cell constant, Measurement unit, Measurement range, Conductivity Zero and Span adjustment values, Temperature calibration value, Transmission output 1 Zero and Span adjustment values, Transmission output 2 Zero and Span adjustment values – can be temporarily changed. However, they revert to their previous value after the power is turned off because they are not saved in the non-volatile IC memory. Do not change setting items (A11, A12, A21 and A22 types). If they are changed, they will affect other setting items. • Setting range of each item is the same as that of keypad operation. • When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used. • If A11, A12, A21 or A22 type is changed at Data item 0005H (A11 type), 0050H (A12 type), 0051H (A21 type) or 052H (A22 type), the A11, A12, A21 or A22 value will default to 0.00 or 0.0. The output status of A11, A12, A21 or A22 will also be initialized. • Settings via software communication are possible while in Set value lock status. • Communication parameters such as Instrument Number, Communication Speed of the slave cannot be set by software communication. They can only be set via the keypad. (p.47) • When sending a command by Global address [95 (7FH), Shinko protocol] or Broadcast address [00H, MODBUS protocol], the same command is sent to all the slaves connected. However, the response is not returned. • When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used for a response.
• Shinko protocol: Error code 4 (34H) • Modbus: Exception code 17 (11H)
data at the time of input short-circuit will be the fixed value 3000 (30.00 %). Also, if 0003H [NaCI salinity (%)] is selected, the response data at the time of input short-circuit will be the fixed value 2500 (25.00 %). 11.7 Conductivity & Temperature Calibrations, Transmission Output 1 & 2 Adjustments via Communication Command 11.7.1 Conductivity Calibration Cell constant may vary due to deterioration of the 4-electrode Conductivity Sensor. To correct the varied cell constant, calibration must be performed. Calibrate Conductivity Zero adjustment first, followed by Conductivity Span adjustment. The following outlines the procedure for conductivity calibration. ① When selecting Last value HOLD (0000H) at Data item 010FH (Transmission output 1 status when calibrating) or 014DH (Transmission output 2 status when calibrating), select it while the 4-elctrode Conductivity Sensor is being immersed in the solution currently measured. ② At this stage, do not immerse the 4-elctrode Conductivity Sensor in the standard solution. ③ Set Data item 0042H (Conductivity calibration mode) to 0001H. The unit moves to Conductivity calibration Zero adjustment mode. If 2 13 , 2 12 digits are read at Data item 0081H (Status flag 1), 01 (During Conductivity calibration Zero adjustment mode) will be returned. ④ Set the Conductivity Zero adjustment value at Data item 0043H (Conductivity Zero adjustment value) so that conductivity becomes 0 (zero). When conductivity is 0 (zero), it is not necessary to adjust. ⑤ Set Data item 0042H (Conductivity calibration mode) to 0000H. Conductivity Zero adjustment is complete, and the unit will revert to Conductivity/Temperature Display Mode. ① Immerse the 4-elctrode Conductivity Sensor in the standard solution. ② Set Data item 0042H (Conductivity calibration mode) to 0002H. The unit moves to Conductivity calibration Span adjustment mode. If 2 13 , 2 12 digits are read at Data item 0081H (Status flag 1), 10 (During Conductivity calibration Span adjustment mode) will be returned. ③ Set the Conductivity Span adjustment value at Data item 0044H (Conductivity Span adjustment value), while checking the conductivity. ④ Set Data item 0042H (Conductivity calibration mode) to 0000H. Conductivity Span adjustment is complete, and the unit will revert to Conductivity/Temperature Display Mode. If Conductivity calibration cannot be performed while calibrating conductivity due to temperature compensation error, Conductivity measurement value error, etc., Error code 1 (Burnout, Short- circuited, etc.) will be returned after 20 to 25 digits are read at Data item 0081H (Status flag 1). To cancel the error code, set Data item 0042H (Conductivity calibration mode) to 0000H. The unit will revert to Conductivity/Temperature Display Mode. If Conductivity Zero/Span adjustment value is set at Data item 0043H (Conductivity Zero adjustment value) or 0044H (Conductivity Span adjustment value) in Conductivity/Temperature Display Mode, the following error code will be returned. • Shinko protocol: Error code 34H • MODBUS protocol: Exception code 11H Temperature calibration is performed by setting temperature calibration value. The following outlines the procedure for Temperature calibration. ①  Set Data item 0040H (Temperature calibration mode) to 0001H. The unit moves to Temperature calibration mode. If 2 13 , 2 12 digits are read at Data item 0091H (Status Flag 2), 01 (During temperature calibration) will be returned. ② Set the Temperature calibration value at Data item 0041H (Temperature calibration value), while checking the temperature. ③  Set Data item 0040H (Temperature calibration mode) to 0000H. Temperature calibration is complete, and the unit will revert to Conductivity/Temperature Display Mode. If Temperature calibration cannot be performed while calibrating temperature due to input error, calibration value error, etc., Error code 1 (Burnout, Short-circuited, etc.) will be returned after 2° to 2° digits are read at Data item 0081H. To cancel the error code, set Data item 0040H (Temperature calibration mode) to 0000H. The unit will revert to Conductivity/Temperature Display Mode. If Temperature calibration value is set at Data item 0041H (Temperature calibration value) in Conductivity/Temperature Display Mode, the following error code will be returned. Shinko protocol: Error code 34H MODBUS protocol: Exception code 11H Fine adjustment of Transmission output 1 is performed. This instrument is adjusted at the factory, however, differences may occur between the indication value of the connected equipment (recorders, etc.) and output value of this instrument. In this case, perform Transmission output 1 Zero and Span adjustments. The following outlines the procedure for Transmission output 1 adjustment. ① Set Data item 0126H (Transmission output 1 adjustment mode) to 0001H. The unit moves to Transmission output 1 Zero adjustment mode. If 2 5 , 2 4 digits are read at Data item 0091H (Status flag 2), 01 (During Transmission output 1 Zero adjustment in Transmission output 1 adjustment mode) will be returned. ② Set the Transmission output 1 Zero adjustment value at Data item 0127H (Transmission output 1 Zero adjustment value), while viewing the value indicated on the connected equipment (recorders, etc.). Setting range:  ±5.00% of Transmission output 1 span ③ Set Data item 0126H (Transmission output 1 adjustment mode) to 0002H. The unit moves to Transmission output 1 Span adjustment mode. If 2 5 , 2 4 digits are read at Data item 0091H (Status flag 2), 10 (During Transmission output 1 Span adjustment in Transmission output 1 adjustment mode) will be returned. ④ Set Transmission output 1 Span adjustment value at Data item 0128H (Transmission output 1 Span adjustment value), while viewing the value indicated on the connected equipment (recorders, etc.). Setting range:  ±5.00% of Transmission output 1 span ⑤ Repeat steps  ① to  ④ if necessary. ⑥ To finish Transmission output 1 adjustment, set Data item 0126H (Transmission output 1 adjustment mode) to 000H. The unit reverts to Conductivity/Temperature Display Mode. Fine adjustment of Transmission output 2 is performed. This instrument is adjusted at the factory, however, differences may occur between the indication value of the connected equipment (recorders, etc.) and output value of this instrument. In this case, perform Transmission output 2 Zero and Span adjustments. The following outlines the procedure for Transmission output 2 adjustment. ① Set Data item 014AH (Transmission output 2 adjustment mode) to 0001H. The unit moves to Transmission output 2 Zero adjustment mode. If 2 °, 2 8 digits are read at Data item 0091H (Status flag 2), 01 (During Transmission output 2 Zero adjustment in Transmission output 2 adjustment mode) will be returned. ② Set the Transmission output 2 Zero adjustment value at Data item 014BH (Transmission output 2 Zero adjustment value), while viewing the value indicated on the connected equipment (recorders, etc.). Setting range:  ±5.00% of Transmission output 2 span ③  Set Data item 014AH (Transmission output 2 adjustment mode) to 0002H. The unit moves to Transmission output 2 Span adjustment mode. If 2°, 2 8 digits are read at Data item 0091H (Status flag 2), 10 (During Transmission output 2 Span adjustment in Transmission output 2 adjustment mode) will be returned. ④ Set Transmission output 2 Span adjustment value at Data item 014CH (Transmission output 2 Span adjustment value), while viewing the value indicated on the connected equipment (recorders, etc.). Setting range:  ±5.00% of Transmission output 2 span 5 Repeat steps ① to ④ if necessary. ⑥ To finish Transmission output 2 adjustment, set Data item 014AH (Transmission output 2 adjustment mode) to 000H. The unit reverts to Conductivity/Temperature Display Mode. When monitoring multiple units of the WIL-102-ECH, set the program so that the requisite minimum pieces of data such as Data item 0080H (Conductivity), Data item 0090H (Temperature), Data item 0081H (Status flag 1), Data item 0091H (Status flag 2) can be read. For other data, set the program so that they can be read only when their set value has been changed. This will speed up the scan time. If any set value is changed by keypad operation, the instrument sets [0081H (Status flag 1) 2¹5: Change in key operation] to 1 (Yes). There are 2 methods of reading the set value changes made by the front keypad. ① On the monitoring software side, check that [0081H (Status flag 1) 2¹⁵: Change in key operation] has been set to 1 (Yes), then read all set values. ② Clear [0081H (Status flag 1) 2¹⁵: Change in key operation], by setting Data item 007FH (Key operation change flag clearing) to 0001H (Clear change flag). If 007FH (Key operation change flag clearing) is set to 0001H (Clear change flag) during the setting mode of the instrument, Error code 5 (35H, Shinko protocol) or Exception Code 18 (12H, MODBUS protocol) will be returned as a negative acknowledgement. And [0081H (Status flag 1) 2¹5: Change in key operation] cannot be cleared. Set a program so that all set values can be read when a negative acknowledgement is returned. ③ Read all set values again after acknowledgement is returned. ① On the monitoring software side, check that [0081H (Status flag 1) 2¹⁵: Change in key operation] has been set to 1 (Yes), then set 007FH (Key operation change flag clearing) to 0001H (Clear change flag). ② Set the program depending on the acknowledgement or negative acknowledgement as follows. When acknowledgement is returned: Consider it as settings completed, and read all set values. When Error code 5 (35H, Shinko protocol) or Exception code 18 (12H, MODBUS protocol) is returned as a negative acknowledgement: Consider it as still in setting mode, and read the requisite minimum pieces of data such as 0080H (Conductivity), 0090H (Temperature), 0081H (Status flag 1), 0091H (Status flag 2), then return to step  ①. Thus, programs which do not affect the scan time can be created using the methods described above, even if set values on the monitoring software will not be updated until settings are complete. • If A□□ type is changed at Data item 0005H (A11 type), 0050H (A12 type), 0051H (A21 type) or 0052H (A22 type), the A11, A12, A21 or A22 value will default to 0.00 or 0.0. Output status of A11, A12, A21 or A22 will also be initialized. First, send the A11, A12, A21, A22 type, then send the A11, A12, A21, A22 value set at Data item 0006H (A11 value), 0053H (A12 value), 0054H (A21 value) and 0055H (A22 value).

14.1 Temperature Compensation Based on the Temperature Characteristics of NaCl When the main ingredient of the salt contained in a sample is NaCl, use temperature compensation method based on the temperature characteristics of NaCI. Conductivity of NaCI solution varies with the ratio based on the conductivity at 25℃  as shown below. The conductivity at 25℃ is calculated on the basis of the conductivity ratio at each temperature in (Table 14.1-1).
14.2 How to Input Temperature Coefficient Temperature compensation is conducted using temperature coefficient (% ⁰ C) and a randomly selected reference temperature. Conductivity of the solution varies depending on the temperature. If temperature rises by 1 ℃, the conductivity rises by 2% at 25 ℃  basis in general. Temperature coefficient differs depending on the solution type and its concentration, which ranges from 0.50  to 2.50. By inputting the temperature coefficient, temperature compensation can be calculated to find the conductivity at 25℃. Temperature coefficient 2.00 %/°C  can be used for most of solutions. If temperature coefficient of solution is already-known, enter the value. (Table 14.2-1) If the conductivity at an arbitrary temperature T ʿ C  is already-known, and if reference temperature is ST'C, conductivity Cודst the reference temperature can be obtained according to the following formula. C(T) C(ST) = (1+0.01×α×(T – ST)) C(sT): Conductivity of the solution at ST°C C(π):   Conductivity of the solution at T°C Temperature coefficient of conductivity (%) α : Arbitrary temperature T°C T: ST: Reference temperature ST°C
