4. PRECAUTIONS 4.1. Installing the scale
Caution
• Ground the scale so that the user will not be subject to an electric shock.
• Do not handle the AC power cable with wet hands.
• The AC plug is not water-resistant. Use an electrical outlet located at a place
where the plug will not get wet.
• Do not handle the cables carelessly.
• Do not install the scale where flammable or corrosive gas is present.
Consider the following conditions to get the most from your scale.
Install the scale where the temperature and relative humidity are stable, with no drafts
or vibration.
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 near equipment which produces magnetic fields.
Do not install the scale in a place where it is possible to be charged with static
electricity, or where the relative humidity is lower than 45% RH. Insulators such as
plastic are often charged with static electricity.
Use a stable power source.
Calibrate the scale before use or after having moved it to another location.
In addition, calibrate it periodically to maintain the accuracy.
(Refer to “11. CALIBRATION”).
4.2. Operating the scale
Periodically ensure that the scale weighs correctly.
Calibrate the scale periodically to maintain the weighing accuracy (Refer to “11.
CALIBRATION”).
Do not place anything on the pan that is beyond the weighing capacity.
Do not apply a shock load to the scale.
Touch the switches only with a finger.
Confirm zero before each weighing to prevent possible error.
4.3. Cleaning the scale
Do not disassemble the scale.
Do not use solvents to clean the scale.
The scale can be washed with water completely.
