3. Precautions
3.1. Installing the Scale
Consider the following conditions to get the most from your scale.
Install the scale where the temperature and relative humidity are stable, there is no draft and a
stable power source is available.
Install the scale on a solid and level surface.
Do not install the scale in direct sunlight.
Do not install the scale near heaters or air conditioners.
Do not install the scale where there is flammable or corrosive gas present.
Do not install the scale near equipment that produces strong magnetic fields.
Do not install the scale where there may be static electricity. When the relative humidity is lower
than
45
%R.H., plastic and isolators are apt to be charged with static electricity.
The display unit is not water resistant. Use the display unit cover to avoid damage.

Remove the protective film from the weighing pan before use.
30
minutes before the scale is used, connect the power (the AC adapter or batteries) and press
the ON/OFF key to turn the display on.
The scale is designed for indoor use. If the scale is used outdoors, it may receive electrical
shock of thunder surge and suffer malfunction and damage.

Do not use a sharp instrument such as a pencil to press the keys. Press the keys gently using
your finger.
Pressing the

error.
Periodically confirm that the weighing value is correct.
