(FCC = Federal Communications Commission in the U.S.A.)6

2. UNPACKING THE BALANCE
2-1 Unpacking
 The balance is a precision instrument. Unpack the balance carefully. Keep the packing
material to be used for transporting the balance in the future.
 The packing contents depend on the balance model. See the illustrations to confirm thateverything is contained.

Standard type: GP-12K/20K/30K/32K/40K/60K/61K/100K/102K

Note
Please confirm that the AC adapter type is correct
for your local voltage and receptacle type.
7

Separate display type: GP-30KS/32KS/60KS/61KS/100KS

Note
Please confirm that the AC adapter type is correct
for your local voltage and receptacle type.

2-2 Installing the Balance
Install the balance as follows:
1. Refer to “3. PRECAUTIONS” for installing the balance.
2. Adjust the leveling feet to level the balance. Confirm it using the bubble spirit level.
3. Confirm that the adapter type is correct for the local voltage and power receptacle type.
4. Connect the AC adapter to the balance. Warm up the balance for at least 30 minutes withnothing on the weighing pan.
8

3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weighing data, note thefollowing:

3-1 Before Use
 Install the balance in an environment where thetemperature and humidity are not excessive. The best
operating temperature is about 20°C / 68°F at about
50% relative humidity.
 Install the balance where it is not exposed to direct sunlightand it is not affected by heaters or air conditioners.
 Install the balance where it is free of dust.
 Install the balance away from equipment which
produces magnetic fields.
 Install the balance in a stable place avoiding vibrationand shock. Corners of rooms on the first floor are best,
as they are less prone to vibration.
 The weighing table should be solid and free fromvibration, drafts and as level as possible.
 Level the balance by adjusting the leveling feet andconfirm it using the bubble spirit level.
 Ensure a stable power source when using the AC adapter.
 Plug in the AC adapter and warm up the balance for atleast 30 minutes.
 Calibrate the balance periodically for accurate weighing.
 When the balance is installed for the first time or has been
moved, warm up the balance for at least 12 hours to allow
the balance to reach equilibrium with the ambient
temperature, and then perform calibration before use.

CautionPlease confirm that the AC adapter type is correct for your local voltage and receptacle type.
Do not install the balance where flammable or corrosive gas is present.

3-2 During Use
 Discharge static electricity from the material to beweighed (hereinafter referred to as sample). When asample could have a static charge, the weighing data
is influenced. Try to keep the ambient humidity above
45%RH or use the metal shield case.

9 This balance uses a strong magnet as part of thebalance assembly, so please use caution whenweighing magnetic materials such as iron. If there is aproblem, use the underhook on the bottom of thebalance to suspend the material away from theinfluence of the magnet.
 Cancel the temperature difference between a sample
and the environment. When a sample is warmer(cooler) than the ambient temperature, the sample will
be lighter (heavier) than the true weight. This error isdue to a rising (falling) draft around the sample.
 Make each weighing gently and quickly to avoid errors
due to changes in the environmental conditions.
 Do not drop things upon the weighing pan, or place asample on the pan that is beyond the balance weighing
capacity. Place a sample in the center of the weighing pan.
 Do not use a sharp instrument such as a pencil topress the keys. Use your finger only.
 Press the RE-ZERO key before each weighing toprevent possible errors.
 Calibrate the balance periodically so as to cancel
possible errors.
 Take into consideration the affect of air buoyancy on asample when more accuracy is required.
 Keep the balance interior free of dust and foreignmaterials.

3-3 After Use Avoid mechanical shock to the balance.
 Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair.
 Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth thatis moistened with warm water and a mild detergent.
 Do not allow the balance to be immersed in water. Even though the balance complies with
IP65 (Dust-tight and Protected Against Water Jets), the balance will not withstand being
completely immersed in water.

3-4 Power Supply
 Do not remove the AC adapter while the internal mass is in motion, for example, right after the
AC adapter is connected, or during calibration using the internal mass.
If the AC adapter is removed under the conditions described above, the internal mass will beleft unsecured, that may cause mechanical damage when the balance is moved.
Before removing the AC adapter, press the ON:OFF key and confirm that zero is displayed.
 When the AC adapter is connected, the balance is in the standby mode if the standby indicatoris on (refer to “3-5 Display Symbols and Key Operation”). This is a normal state and does notharm the balance. For accurate weighing, keep the AC adapter connected to the balance and AC
power unless the balance is not to be used for a long period of time.
10

3-5 Display Symbols and Key Operation

3-6 Smart Range Function
The GP-32K, GP-32KS and GP-102K are equipped with two ranges. The precision range has ahigher resolution. The standard range has normal resolution.
The range is switched automatically, depending on the value displayed. Pressing the RE-ZERO key
allows weighing in the precision range, regardless of the tare value. (Smart range function)
The range can be fixed to the standard range, by pressing the SAMPLE key.
Note
Once the range is switched to the standard range, it will not switch to the precision range
automatically even when the displayed value becomes within the precision range value. Use
the RE-ZERO or SAMPLE key to activate the precision range again.

Below is a description of how the Smart Range actually functions, using the GP-102K(Precision range=61 kg×1 g, Standard range=101 kg×10 g)

1 Press the RE-ZERO key.
The balance will start weighing, using the
precision range.
2 Place a container, on the weighing pan, to be
used as a tare.
The value displayed exceeds the precision
range value. So, the range will be switched tothe standard range.
3 Press the RE-ZERO key.
The balance will be switched to the precision
range.
4 Place a sample on the pan.
The value displayed is within the precision
range value. So, the balance will perform aweighing, using the precision range.

7. CALIBRATION
7-1 Calibration GroupThe GP series balance has the following modes as a calibration group.
Calibration
 Automatic self calibration (calibration due to changes in temperature) Calibration using the internal mass (one-touch calibration)
 Calibration using an external weight
Calibration test
 Calibration test using an external weight (Calibration test does not
perform calibration.)
Correction of the internal mass value

Terms
The following terms are defined as follows:
Internal mass
= Built-in calibration weight
External weight= A weight that you have. Referred to as a calibration weight when used for calibration.
Calibration weight = A weight used for calibration
Target weight= An external weight used for calibration test

Caution Calibration adjusts the balance for accurate weighing.
Besides periodic calibration and before each use, perform calibration when:• the balance is installed for the first time.
• the balance has been moved.
• the ambient environment has changed.
 Do not allow vibration or drafts to affect the balance during calibration.
 To output the data for GLP using the RS-232C interface, set “GLP output (info)” of “Dataoutput (dout)”. For details, refer to “9. FUNCTION TABLE”. Time and date are added to the
GLP report. If the time or date is not correct, adjust them. For details, refer to “9-9 Clock andCalendar Function”.
 Calibration test is available only when “GLP output (info)” of “Data output (dout)” is set to “1” or “2”, The calibration and calibration test data can be stored in memory. To store them, set “Datamemory (data)” to “3”. For details, refer to “11. DATA MEMORY”.

Display This indicator means “the balance is measuring calibration data”.

Do not allow vibration or drafts to affect the balance while thisindicator is displayed.

7-2 Automatic Self Calibration (Calibration due to changes in temperature)
This function automatically calibrates the balance when the balance detects an ambient temperaturechange. If GLP output is selected in the function table, the balance outputs the calibration report orstores the data in memory. Automatic self calibration functions even if the display is turned off(standby state).

CautionIf something is on the weighing pan, the balance judges that it is in use and does not perform
automatic self calibration. To maintain the calibrated state, keep the weighing pan clear while
not in use.
The displays shown below are related to the automatic self calibration.
Indicates that the balance detects a change in ambient
temperature and automatic self calibration will start. If the balance
is not used for a few minutes with this indicator blinking, thebalance performs automatic self calibration. The blinking duration
depends on the environment.
Indicates that the balance is measuring calibration data. Do notallow vibration or drafts to affect the balance while this indicator isdisplayed. After calibration, the balance returns to indicate theprevious display.

The GP series balance is of the DCE type (Data Communication Equipment), which can beconnected to a personal computer using the RS-232C interface.
Before connection, read the personal computer manual thoroughly.
Use a standard DCE cable for connection (cable type: straight-through).
When the personal computer type is a DOS/V with a 9-pin port, use a straight-through cable witha 25-pin male connector and a 9-pin female connector.

15-3 Using Windows Communication Tools (WinCT)
When Windows is used as an operating system in a personal computer, the WinCT software can beused to transmit the weighing data to the personal computer.
The WinCT software has two communication methods: “RsCom”, “RsKey” and “RsWeight”. For
details on WinCT, refer to the WinCT instruction manual.

RsCom Can transmit commands to control the balance.
 Can make bi-directional communication between the balance and a personal computer using
the RS-232C interface.
 Can display or store the data using a text file format. Can also print the data using a printerconnected to the personal computer.
 When several ports of a personal computer have balances connected, can communicate witheach balance simultaneously.
 Can share a personal computer with other application software.
 Can receive the balance GLP report.

RsKey Can transmit the weighing data output from the balance directly to other application software
such as Microsoft Excel.
 Can be used with most application software.
 Can receive the balance GLP report.

RsWeight
 The weighing data transmitted from the balance can be displayed in graph from on the monitor
in real-time.
 The axis scale of a graph automatically alters according to the data. It can be also changed
manually.
 The graph can be printed out using a printer.
 The recorded data can be saved in CSV format.
 Maximum, minimum, average, standard deviation and coefficient of variation values can becalculated and displayed on the monitor.

15-4 Using the WinCT software, the balance can do the following:
1 Analyzing the weighing data and the statistics with “RsKey”
The weighing data can be input directly into an Excel worksheet. Then, Excel can analyze thedata to obtain total, average, standard deviation, maximum and minimum value, and display
them in a graph.
2 Controlling the balance using commands from a personal computer
By using “RsCom”, the personal computer sends commands such as “re-zero” or “sendweighing data” to the balance and controls the balance.
3 Printing the balance GLP report using your printerThe balance GLP report can be printed using a printer connected to the personal computer.
4 Receiving weighing data at a certain interval
The weighing data can be received at a certain interval and data characteristic with elapsed
time can be obtained.
5 Using the GP series balance memory function
The data can be stored in the balance’s memory. Of the data stored, the weighing data andcalibration data can be transmitted to a personal computer at one time.
6 Using a personal computer as an external indicator
With the “RsKey” test mode function, a personal computer can be used as an external weightindicator for the balance. (To do this, set the balance data output mode to stream mode.)8116. COMMANDS

8216-2 Acknowledge Code and Error Codes
When the “Serial interface function (5if)” parameter is set to “erCd 1”, the balance outputs <AK>code or error code to each command as follows:<AK> (06h)Acknowledge in ASCII code.

 When the balance receives a command to request data and can not process it, the balancetransmits an error code (EC, Exx).
When the balance receives a command to request data and can process it, the balance
outputs the data.
 When the balance receives a command to control the balance and can not process it, thebalance transmits an error code (EC, Exx).
When the balance receives a command to control the balance and can process it, the balancetransmits the acknowledge code.
Among commands to control the balance, the following transmit the acknowledge code bothwhen the balance receives the command and when the balance has accomplished thecommand. If the command can not be processed properly, the balance transmits an error code
(EC, Exx). This error can be released using the CAL command.
CAL command (Calibration command)

ON command (Display ON command)

P command (Display ON/OFF command)

R command (RE-ZERO command) When a communication error has occurred due to external noise, or a parity error has occurred
due to transmission error, the balance transmits an error code. In this case, send the commandagain.

16-3 Control Using CTS and RTS
Depending on the “Ct5” parameter of “Serial interface (5if)”, the balance performs as follows:

Ct5 0
Regardless of whether the balance can receive a command or not, the balance keeps the CTS line
HI. The balance outputs data regardless of the condition of the RTS line.

Ct5 1
The CTS line is kept Hi normally. When the balance can not receive the next command (e.g. while
the balance is processing last command), the balance sets the CTS line to Lo. The balance confirms
the level of the RTS line before outputting a set of data. If the RTS level is Hi, the balance outputs
data. If the RTS level is Lo, data is not output (The data is canceled).

16-4 Settings Related to RS-232C
Concerning the RS-232C, the balance has two functions: “Data output (dout)” and “Serial interface(5if)”. Set each function as necessary.

8317. MAINTENANCE
 Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair.
 Use the original packing material for transportation.
 Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth thatis moistened with warm water and a mild detergent.
 The mass of the internal mass may change due to corrosion or other damage caused by the operating
environment, or due to aging. Check the internal mass using an external weight periodically.

Stable value

The stable weight data, indicated by the illuminated stabilization indicator.

Environment

Ambient conditions such as vibration, drafts, temperature, static electricity
and magnetic fields which affect the weighing operation.

Store

To save the weighing data, unit mass or calibration data using the data
memory function.

Calibration

Adjustment of the balance so that it can weigh accurately.

OutputTo output the weighing data using the RS-232C interface.

Zero point

A weighing reference point. Usually refers to the value displayed whennothing is on the weighing pan.

Smart range function Allows weighing in the precision range, even if a heavy tare is used.
Data number

Numbers assigned sequentially when weighing data or unit weight is stored.

Digit

The minimum weighing value available. Used for the balance, 1 digit is thesmallest displayable mass.

Tare

To cancel the weight of a container which is not to be included in theweighing data. Normally, refers to an operation of placing a container andsetting the display to zero.

Mode

Balance operational function.

Re-zeroTo set the display to zero.

GLP

Good Laboratory Practice.

Repeatability

Variation in measured values obtained when the same mass is placed andremoved repetitively. Usually expressed as a standard deviation.
e.g. Standard deviation=1 digit: This means that measured values, obtained
when the same sample is placed and removed repetitively, fall within ±1 digitin the frequency of about 68%.

Stabilization time

Time required after a sample being placed, until the stabilization indicatorilluminates and the weighing data is displayed.

Sensitivity drift

An affect that a change in temperature causes to the weighing data.
Expressed as temperature coefficient.
e.g. Temperature coefficient = 3 ppm/°C : If a load is 20 kg and thetemperature changes by 10°C, the value displayed changes by the following
value.
0.0003%/°C x 10°C x 20 kg = 0.6 g
In this example, if the value displayed is 20.0000 kg before temperaturechanges, a temperature change of 10°C will make the value displayed
20.0006 kg.
