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 that everything 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 with nothing on the weighing pan.

8

3. PRECAUTIONS

To get the optimum performance from the balance and acquire accurate weighing data, note the following:

3-1 Before Use

Install the balance in an environment where the temperature 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 sunlight and 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 vibration and 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 from vibration, drafts and as level as possible.

Level the balance by adjusting the leveling feet and confirm 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 at least 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.

Caution

Please 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 be weighed (hereinafter referred to as sample). When a sample 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 the balance assembly, so please use caution when weighing magnetic materials such as iron. If there is a problem, use the underhook on the bottom of the balance to suspend the material away from the influence 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 is due 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 a sample 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 to press the keys. Use your finger only.

Press the RE-ZERO key before each weighing to prevent possible errors.

Calibrate the balance periodically so as to cancel possible errors.

Take into consideration the affect of air buoyancy on a sample when more accuracy is required.

Keep the balance interior free of dust and foreign materials.

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 that is 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 be left 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 indicator is on (refer to “3-5 Display Symbols and Key Operation”). This is a normal state and does not harm 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 a higher 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 to the 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 a weighing, using the precision range.

Note

Up to 50 unit masses can be stored in memory for the multiple sample. For details, refer to

“11. DATA MEMORY”.

Counting mode using the ACAI function

The ACAI is a function that improves the accuracy of the unit mass automatically by increasing the number of samples as the counting process proceeds.

8 If a few more samples are added, the processing indicator turns on. To prevent an error, add three or more. The processing indicator does not turn on if overloaded. Try to add the same number of samples as displayed.

9 The balance re-calculates the unit mass while the processing indicator is blinking. Do not touch the balance or samples on the pan until the processing indicator turns off.

10 Counting accuracy is improved when the processing indicator turns off.

Each time the above operation is performed, a more accurate unit mass will be obtained.

There is no definite upper limit of ACAI range for the number of samples exceeding 100. Try to add the same number of samples as displayed.

7. CALIBRATION

7-1 Calibration Group

The GP series balance has the following modes as a calibration group.

Calibration Automatic self calibration (calibration due to changes in temperature)

Calibration test

Calibration using the internal mass (one-touch calibration)

Calibration using an external weight

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 “Data output (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 and

15-3 Using Windows Communication Tools (WinCT)

When Windows is used as an operating system in a personal computer, the provided WinCT software can be used to transmit the weighing data to the personal computer.

The WinCT software has two communication methods: “RsCom” and “RsKey”. 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 printer connected to the personal computer.

When several ports of a personal computer have balances connected, can communicate with each 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.

Note

Windows and Excel are registered trademarks of Microsoft Corporation.

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 the data 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 “send weighing data” to the balance and controls the balance.

3 Printing the balance GLP report using your printer

The 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 and calibration 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 weight indicator for the balance. (To do this, set the balance data output mode to stream mode.)

P command (Display ON/OFF command)

ON command (Display ON 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 command again.

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.

82

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 that is 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.

18. TROUBLESHOOTING

18-1 Checking the Balance Performance and Environment

The balance is a precision instrument. When the operating environment or the operating method is inadequate, correct weighing can not be performed. Place a sample on the pan and remove it, and repeat this several times. If the balance seems to have a problem with repeatability or to perform improperly, check as described below. If improper performance persists after checking, contact the local A&D dealer for repair.

Checking that the balance performs properly

Check the balance performance using the self-check function as described in “6-1 Automatic

Response Adjustment / Self Check Function”.

An error display appears when a malfunction is found.

Check the balance repeatability using an external weight. Be sure to place the weight in the center of the weighing pan.

Check the balance repeatability, linearity and calibrated value using external weights with a known value.

Checking that the operating environment or weighing method is proper

Operating environment

Is the weighing table solid enough?

Is the balance level? Refer to “3-1 Before Use”.

Is the operating environment free from vibration and drafts?

Is there a strong electrical or magnetic noise source such as a motor near the balance?

Weighing method

Is the weighing pan installed correctly?

Is the RE-ZERO key pressed before placing a sample on the weighing pan?

Is the sample placed in the center of the weighing pan?

Has the balance been calibrated using the internal mass (one-touch calibration)?

Has the balance been warmed up for 30 minutes before weighing?

83

Sample and container

Has the sample absorbed or lost moisture due to the ambient conditions such as temperature and humidity?

Has the temperature of the container been allowed to equalize to the ambient temperature?

Refer to “3-2 During Use”.

Is the sample charged with static electricity? Refer to “3-2 During Use”.

Is the sample of magnetic material such as iron? Caution is required for weighing magnetic materials. Refer to “3-2 During Use”.

Good Laboratory Practice.

Variation in measured values obtained when the same mass is placed and removed 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 digit

Stabilization time

Sensitivity drift in the frequency of about 68%.

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

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 the temperature 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 temperature changes, a temperature change of 10 °C will make the value displayed

20.0006 kg.
