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:
Do NOT overload the scale. This will damage the
loadcell and void the warranty.
Do NOT leave load hung on the scale for long. This
will decrease the scale’s accuracy and shorten the
loadcell’s life.
Inspect shackle and hook before using.
When the scale runs out of power, replace the
battery with fresh ones.
Do NOT use the scale under thunder or rain.
Do NOT attempt to repair the scale yourself.

3. Operation Guide
Power On
Press for 1 second
to power up, battery tests
and initializes.
Screen shows
detection message
while scale detects
its load and
auto-zero itself.
Power Off
Press for 1 second
to power off scale.
Display shows
power-off message.

Tare
Press to store
weight as tare.
“TARE” shows
and weight turns
zero.
If weight is over
100%F.S., or less
than 0, tare is not allowed.
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).
Press to restore tare.
“TARE” hides,
and weight
resumes in gross
mode.

Hold
Press to lock the
display.
“HOLD” shows
and display is frozen.
Press again to
resume display.
“HOLD” hides
and display
resume refreshing.
Unit Switch
Press for 1 second
to switch measuring unit
between kg, lb and N.
If scale is tared, or
held, unit
switching is not
allowed.

Page 9 of 13
Zero
Press for 1 second
to zero scale.
“ZERO” shows
and weight turns
zero.
If weight is tared,
or not stable, or
held, zero is not allowed.
If weight is over Manual-Zero range, zero
is not allowed.
Setting
Press and sim
ultaneously, and hold the
two buttons for 1 second,
to enter Setting Mode.
Press to enter
Auto-Off option; and
press to change
Auto-Off option.

15 (15min), 30 (30min), 60 (60min).
Press to enter
Auto-Zero option; and
press to change
Auto-Zero option.
Auto-Zero can be set to 0 (disabled), 2
(2%F.S.), 4 (4%F.S.), 10 (10%F.S.), 20
(20%F.S.), 50 (50%F.S.).
Press to enter
Manual-Zero option; and
press to change
Manual-Zero option.
Manual-Zero can also be set to 0 (disabled),
