4 Caution
4.1 Precautions for Installing the Scale
Consider the following conditions to get the most from your scale.
The best operation is where the temperature and relative humidity are stable, the
scale is installed on a solid floor or bench and there is no draft.
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 which produces magnetic fields.
Do not install the scale where there is likely to be static electricity discharges in a
place where the relative humidity is lower than 45%RH. Plastic and isolators are
likely to be charged with static electricity.
The display unit is not water resistant. Use the display unit cover to avoid
damage.
Do not use an unstable power source.
4.2 Precautions for Operating the Scale
Periodically check the scale with a known weight.
Calibrate the scale before using it and after moving it to another location.
Do not place anything on the pan which is heavier than the weighing capacity
Do not drop anything onto the pan.
Do not use a sharp instrument such as a pencil or ball-point pen to press the
switches. Press the switches gently using only your finger.
We recommend pressing the ZERO or TARE switch before each weighing to
prevent possible error.
Replace used dry cells with six new ones when the BATT symbol is displayed.
Dry cell (battery) is size D.
4.3 Precautions for Storing the Scale
Do not disassemble the scale.
Do not use solvents to clean the scale.
For best cleaning of the display unit, wipe with a dry lint free cloth or a lint free
cloth which is moistened with warm water and a mild detergent.
The base unit can be cleaned with gentle water jets while brushing the base unit.
Weigh only after the unit is dry.
Protect the display unit from dust and water by using the vinyl cover.
Remove batteries from display unit when the scale is not in use for a long time. If
you leave the batteries installed they may leak and damage the scale.
