1.Introduction

This manual describes how the balances of GH series work and how to get the most out of them 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, the balance's construction and basic
	operation.
Adapting to the environment ....	Describes response (and stability) adjustment to adapt to the
	environment where there is vibration or drafts, the way to
	maintain weighing precision in a variation of ambient
	temperature, calibration and calibration test.
Selecting functions	Describes functions of the balance.

Interface and communication ... Describes the serial interface used for communicating with a computer that requests weighing data and controls the balance, and for use with a printer

Maintenance	Describes maintenance, error codes, troubleshooting,
	specifications and options.
