1. INTRODUCTION
This manual describes how the GP series balance works and how to get the most out of it in terms
of performance.
Read this manual thoroughly before using the balance and keep it at hand for future reference.
1-1 About This Manual
This manual consists of the following five parts:
Basic operation .............................. Describes precautions on handling the balance, balance
construction and basic balance operation.
Adapting to the environment .......... Describes response adjustment, calibration and calibration
test.
Functions ....................................... Describes various functions of the balance.
RS-232C serial interface................... Describes RS-232C serial interface output and external contact
input. The RS-232C serial interface outputs weighing data and
controls the balance. The external contact input commands the
balance re-zeroing and data output.
Maintenance................................... Describes maintenance, error codes, troubleshooting,
specifications and options.
1-2 Features
Large Vacuum Fluorescent Display, easy to read.
Dust-tight and Protected Against Water Jets (Complying with IP65), allows washing with water.
Built-in Calibration Weight (hereinafter referred to as internal mass), allows easy calibration,
adjustment and maintenance of the balance.
Automatic Self Calibration, using the internal mass, adapting to changes in temperature.
Self Check Function, provided to self-check the balance using the internal mass.
Automatic Response Adjustment, adapting to vibration and drafts in the environment.
High Response Speed, the time to read a displayed value after a sample is placed on the pan
has been shortened by using the Super Hybrid Sensor (SHS). (Approx. 1.5 seconds when
FAST is selected for the response rate.)
Data Memory Function, storing weighing data, calibration data or unit mass in the counting
mode. It can also store tare values or upper and lower limit values for the comparator function.
Interval Memory Mode is provided to store the weighing data periodically.
Good Laboratory Practice (GLP) data output using the standard RS-232C serial interface.
Clock and Calendar Function, adding the time and date to the output data.
Comparator Indicators, displaying the comparison results, H I, OK or LO.
Capacity Indicator, displaying the weight value in percentage relative to the weighing capacity.
4
Hold Function, provided for weighing a moving object such as an animal.
Multiple Weighing Units, with most of the common units used around the world.
Density Mode, for calculating the density of a solid.
Accumulation Function, adding the weight values and outputting the sum.
Adjustable Display Position, the standard type balance has a swing-arm to adjust the display
position for optimum viewing.
Separate display type balances (GP-30KS/32KS/60KS/61KS/100KS) are also available.
Windows Communication Tools (WinCT), allows easy communication with Windows.
Windows is a registered trademark of Microsoft Corporation.
Reference Card, provided for a quick reference to the balance operation.
Underhook, available as an option, for measuring density and weighing magnetic materials.
Comparator Output (OP-04) and Analog Voltage Output (OP-06) are available as options.

1-3 Compliance
Compliance with FCC Rules
Please note that this equipment generates, uses and can radiate radio frequency energy. This
equipment has been tested and has been found to comply with the limits of a Class A
computing device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed to
provide reasonable protection against interference when equipment is operated in a
commercial environment. If this unit is operated in a residential area, it may cause some
interference and under these circumstances the user would be required to take, at his own
expense, whatever measures are necessary to eliminate the interference.
(FCC = Federal Communications Commission in the U.S.A.)
Compliance with EMC Directives
This device features radio interference suppression in compliance with valid
EC Regulation 89/336/EEC.

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.
8
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.
