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.
