Setup should be done before using this instrument according to the user’s conditions:
Setting the Resistivity input, Temperature input, EVT1, EVT2, EVT3 (EVT3 option) and
EVT4 (EVT3 option) types, Serial communication (C5 option), Transmission output 1,
Transmission output 2 (TA2 option), and Indication settings (Backlight selection,
Resistivity color, etc.)
Setup can be conducted in the Resistivity Input Group, Temperature Input Group, EVT1,
EVT2, EVT3, EVT4 Action Groups and Basic Function Group.
If the user’s specification is the same as the factory default of the AER-102-SE, or if setup
has already been complete, it is not necessary to set up the instrument. Proceed to
Section “8. Calibration (p.42)”.
7.1 Turn the Power Supply to the AER-102-SE ON.
For approx. 4 seconds after the power is switched ON, the following characters

Resistivity input sensor correction
0.00 M •cm• Sets resistivity input sensor correction value.
This corrects the input value from the resistivity sensor. When asensor cannot be set at the exact location where measurement isdesired, sensor-measured resistivity may deviate from the resistivity
in the measured location. In this case, desired resistivity can beobtained by adding a sensor correction value.
However, it is effective within the measurement range regardless ofthe sensor correction value.

• Setting range: 1 to 120• Resistivity (Temperature) Filter Time Constant
Even when resistivity (temperature) measured value before filter process changes asshown in (Fig. 7.3-1), if the filter time constant “T” is set, the resistivity (temperature)measured value changes as shown in (Fig. 7.3-2) so that resistivity (temperature)measured value after finishing filter process can reach 63% (of the desired value)
after T seconds have passed. If the filter time constant is set too large, it affects EVT
action due to the delay of response.
(e.g.) In case the LSD (least significant digit) of the resistivity (temperature) measured
value prior to filter process is fluctuating, it can be suppressed by using the filter
time constant.

8. Calibration
The Resistivity calibration Span adjustment mode, Temperature calibration mode, andTransmission output 1 and 2 adjustment modes are described below.
8.1 Resistivity Calibration Span Adjustment Mode
Cell constant sometimes varies due to deterioration of 2-electrode Resistivity Sensor.
To correct this cell constant, calibration is required.
Adjust the correction value so that resistivity input value matches the reference
resistivity meter.
The following outlines the procedure for Resistivity calibration span adjustment.

8.2 Temperature Calibration ModeTo calibrate a temperature, set a temperature calibration value.
If(No temperature compensation) is selected in [Temperaturecompensation method (p.25)], and if(Unlit) or(Reference
temperature) is selected in [Temperature Display when no temperature compensation(p.41)], Temperature calibration mode is not available.
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 ,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

For Resistivity calibration Span adjustment, adjust so that

When a sensor cannot be set at the exact location where
measurement is desired, the resulting measured
temperature may deviate from the temperature in thedesired 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.

Error Alarm

Detects actuator trouble.
Even if resistivity input error alarm time has elapsed, and if
resistivity input does not become higher than resistivity
input error alarm band, the unit assumes that actuator
trouble has occurred, and sets Status flag 2 (EVT1, EVT2,
EVT3, EVT4 output flag bit).
In Serial communication, status can be read by reading
Status flag 2 (EVT1, EVT2, EVT3, EVT4 output flag bit).
When(Resistivity input error alarm output) is

However, they revert to their previous value after the

This corrects the input value from the resistivity sensor. Whensensor-measured resistivity may deviate from the resistivity
in the measured location, the desired resistivity can beobtained by adding a sensor correction value.
However, it is effective within the measurement range

12. Temperature Compensation Method12.1 How to Input Temperature Coefficient
Temperature compensation is conducted using temperature coefficient (%/ ) and arandomly selected reference temperature.
Conductivity of the solution varies depending on the temperature.
If solution 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 %/ can be used for most of solutions.
If temperature coefficient of solution is already-known, enter the value.
If the conductivity at an arbitrary temperature T is already-known, and if reference
temperature is ST , conductivity C(ST) at 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(T): Conductivity of the solution at T
α: Temperature coefficient of conductivity (%)
T:
Arbitrary temperature T
ST: Reference temperature ST
12.2 Temperature Compensation Based on the Temperature Characteristics ofDeionized Water
Conductivity of deionized water is calculated by adding conductivity of deionized water
to conductivity caused by ionic impurities.
C(T) = F(T) + G(T)
C(T): Conductivity of solution at T
F(T): Conductivity of deionized water at T
G(T): Conductivity caused by ionic impurities at T
Conductivity of Deionized Water
Conductivity of deionized water is caused by dissociation of water molecules.
The dissociation of water molecules is greatly affected by the change oftemperature.
Conductivity of deionized water is measured based on the characteristics in (Table
12.2-1) (ASTM D 1125-91, JISK0130-1995).
