This analytical balance works on electromagnetic force compensation
technology and micro processor which implements high speed stabilization
and high reliability. It can be widely used in industry, agriculture, commerce,
schools, scientific research and other institutions to quickly weighing the quality
and quantity of objects.
Safety Precautions
Verify that the AC Adapter input voltage matches the local AC power supply.
Use the scale only in dry locations.
For best results, use the scale in the specified optimum operating temperature.
Use your scale with care, gently loading items to be weighed onto the center of
the pan. Avoiding rough treatment will aid in the life of your scale.
Do not suggest to use in below environment.

weighing mode.
When the operating temperature changes, put the balance in the new place
for 2 hours under the “power on” state to adapt the balance to the new
temperature.
Attention: If the number on display is not stable at the first usage, it is
caused by the temperature difference of the environment, you can
press ”TARE”button repeatedly and let it stand for 30 minutes.
In order to get accurate weighing result, balance should be
calibrated
before the below usage scenarios.
Before first use
Balance power off for long time or power error.
After changing the operating environment.
Regularly in weighing procedure.

Problem Cause Solution
No power supply;
Fuse damaged;
Power transformer is damaged;
Bad working conditions; Air flow
Something between the scale pan
and working table.
The power exceeds its permissible
value and is unstable;
Static electricity
Improper calibration
The weight of the recipient has
not been tared
Big temperature difference
The balance is not horizontal
Plug in adapter; Change the
fuse;
Change the power transformer;
If problem persists, send the
balance to the Technical
Service for repair.
Improve the working condition,
Close the windshield;
