1. Introduction

This manual describes how the balances of the GX-K series and GF-K 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.

1-2. Features

Large vacuum fluorescent display (VFD), easy to read.
Dust-tight and protected against water jets, allows washing with water. A waterproof
RS-232C cable (GX-07K) is available as an option.
Built-in calibration weight (hereinafter referred to as the internal mass) of the GX-K series,
allows easy calibration, adjustment and maintenance of the balance.
Automatic self calibration of the GX-K series, using the internal mass, adapting to changes
in temperature.
Automatic self-check function to check itself by one key operation.
The response speed of the GX-K series, adapting to drafts and vibration after self-checking
the balance.
High response speed: The time to read a displayed value after a sample is placed on the
pan has been shortened by using a super hybrid sensor (SHS).
