1. Introduction
This manual describes how the balances of HR-i 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.
1.2. Features
