5. INSTRUCTION FOR USE
5.1 BEFORE WEIGHING
Make sure that:
a. The scale is placed on a level and strong
surface.
b. The plastic platter is placed correctly on top
of load receptor and the stainless steel
platter cover is placed on the plastic platter.
c. The scale is turned on.
d. The ZERO INDICATOR is on. If not, press ON/ZERO
to set display to zero.
5.2 WEIGHING
a. Always place an object onto the platter gently.
Excessive force applied to platter may cause
damages to sensor inside scale.
b. The weight of the object would be displayed
automatically.
c. It is a good practice to remove all loads from
platter after weighing. It would prolong the
lifetime of scale.
5.3 SELECT WEIGHT UNIT
Press MODE to shift among various weight units
(gram, lb/oz and Taiwanese) with or without
backlight if required. Refer to 4.2.2 for internal
setting procedures.

The weight unit (used before power off) would be
employed when the scale is turned on again.
5.4 SET DISPLAYED VALUE TO ZERO WHEN UNLOADED
Press ON/ZERO to set weight displayed to zero when
unloaded. Refer to SPECIFICATIONS for maximum zero
range.
5.5 TARE OFF THE WEIGHT OF A CONTAINER
When a container is used, follow the below steps to
tare off the weight of it and get a net weight
result.
a. Remove all loads away from platter
b. Make sure that zero weight and the ZERO
INDICATOR appear. If not, refer to 5.4 to set
display value to zero.
c. Place the container on the platter.
d. Press TARE.
After TARE is pressed, NET INDICATOR and then a
zero weight value would be displayed. In this case,
the ZERO INDICATOR will not appear even though a
zero weight is displayed.
Refer to 5.2 for weighing procedures. Weight
displayed is the net weight of the subject matter.
Refer to SPECIFICATIONS for maximum tare range.

5.6 CLEAR THE TARE FUNCTION
a. Remove all loads from platter.
b. The scale will appear a negative value, which
is the weight of the container, and the ZERO
INDICATOR appears.
c. Press TARE.
d. After TARE is pressed, a zero weight will be
displayed while the ZERO INDICATOR remains.
5.7 LO-BAT INDICATOR
When the LO-BAT INDICATOR appears, it means that
the battery is faded out. Replace all battery with
new ones, or apply the external power adaptor
immediately.
CAUTION:
When the power adaptor is being used, take out all
battery from the battery pack. Failure to do so may
cause battery leak/ explosion or damages to the
scale.

apply the power adaptor immediately.
CAUTION: when the power adaptor is
being used, take out the battery from
the battery pack. Failure to do so may
cause battery leak/explosion or damages
to the scale.
Syndrome Weighing result is not accurate
Check: Is the scale placed in a level
condition?
Action: Relocate the scale to obtain a level
condition.
Check: Is the scale affected by airflow,
