Using the scale with batteries
Using the scale with the power adapter
What is the purpose of the TARE/ZERO key?
Weighing an item
You require a 9V new alkaline battery.
Remove the battery compartment cover underneath the scale, and insert the
battery as indicated. Ensure that they are inserted the correct way around.
Replace the battery compartment cover.
Place the container onto the platform, and then touch the key. The display
will show
Place the item to be weighed into the container, on the weigh platform. The scale
will now show the weight of the item, excluding the weight of the container.
Connect the supplied power adapter to the input socket at the rear of the scale,
and plug it into the power supply. It is advisable to remove the battery when using
power adapter.
You can tare (set to zero) any article used as a container for small items, in the
following way.
If the scale is switched off, touch the key and wait for to be
displayed.
Touch the key. A sign will appear on the display for a short
while, during such time the scale performs a self-check/zeroing routine, and then
displays on the LCD.
Your scale is now ready to weigh. After placing an item onto the platform, there is
a delay of approximately one second before the weight display appears.

Unpacking and Assembling your scale
Unpack the scale and take out the pieces of shock protector inserted in between
the platform and the scale.
Be sure that the scale is operated on a flat surface
In order to operate correctly, the scale must be installed on a firm, flat surface. It
advisable to keep the scale on for about 1~2 minutes before use.
Scale calibration
In case the scale loses it’s accuracy then the re-calibration of the scale may be
needed.
Unpack scale and if the scale did come from a colder or warmer
environment let it first stay for sometime to be at the same temperature as
your current environment.
Plug in the DC power supply at the back of the scale.
Press the ON key and hold it for about 6~ 8 seconds, the scale will enter the
calibration mode (model select mode first). “E0” will be displayed on the LCD.
Press the ON key to change the scale model (within 5 seconds the E0 is
displayed), the display will change from “E0” to “E1”. Press the ON key again to
change the display to E.2 and again until you see E4 displayed on the LCD. Once
the “E4” is displayed on the LCD, wait until the scale displays the base frequency.
The base frequency (without anything on the platform) should be around 120.
The scale should show the ZERO value nominal (base frequency) about 120
If shows below 100 or over 140 it must be adjusted at the internal potentiometer.
(To access this adjustment the scale must be opened and this should only be done
by qualified technicians)
If the base frequency (0kg frequency)is not in the range of 100~140 the scale
doesn’t proceed the calibration.
A “1” will be displayed, put 1.5kg on the platform and wait. A “2” will be displayed.
Remove the weight and place 3 kg on the platform and wait. A “3” appears on the
display. Remove the weight on the platform and place 4.5kg on the platform.
A “E” appears on the display indicating the end of the calibration.
Turn Scale Off.
Calibration is Completed.
This calibration procedure can be repeated anytime in case the scale was severely
overloaded. The load cell of this precision scale is normally protected against
overloaded applied slowly, but overload caused by dropping the scale or dropping
something heavy on the scale may require re-calibration or re-adjustment of the
ZERO potentiometer in case the Zero is not in the range of 100-140.
It is recommended to calibrate the scale at first once you receive it.. If you have the
