1. Introduction
Notice
Before you use the scale, please read this manual
through carefully, and keep it properly for future use.

Safety Guide
For good performance and precise measurement, be
careful with daily operation and maintenance. Note the
following instructions:

Â

Do NOT overload the scale. This will damage the
loadcell and void the warranty.

Â

Do NOT leave load hung on the scale for long. This
will decrease the scale’s accuracy and shorten the
loadcell’s life.

Â
Â

Inspect shackle and hook before using.
When the scale runs out of power, replace the
battery with full ones.

Â
Â

Do NOT use the scale under thunder or rain.
Do NOT attempt to repair the scale yourself.
Contact your local representative.

If weight is not stable or held, tare is not
allowed.

‡

Taring will reduce scale’s apparent
overloading range. E.g., if a 10kg container
is tared and scale’s maximum capacity is
50kg, scale will overload at a new weight of
40.18kg (5000 – 1000 + additional 9

)

divisions).
