PRECAUTIONS
Place the scale on a flat and stable surface.
Verify that the input voltage and the plug type matches the local AC power supply.
Warm up the scale for 15 minutes before using it for the first time.
Keep the scale away from EMI noise, strong wind and vibration, which might
cause incorrect reading.
Avoid sudden temperature changes (suitable operating temperature is between 0~40℃)
Disconnect the power supply when cleaning the scale.
Do not immerse the scale in water or other liquids.
Service should be performed by authorized personnel only.
BEFORE USING THE BALANCE
Unpacking and Checking
Open the package and check the instrument for transport damage.
Immediately inform your dealer if you have complaints or if parts are missing.
The package should contain:
1. Scale body 2. User manual

Leveling the Scale
To compensate for small irregularities or inclinations at the location, the
scale can be leveled. The scale is equipped with a level indicator at the front
panel .Adjust the leveling feet until the air bubble in the indicator is centered
as shown.
Note: The scale should be leveled each time once its location is changed.
