3.0 LOCATING THE SCALE
•Place the scale on a stable surface. A soft and uneven floor (e.g. carpet,
linoleum) could cause an erroneous weight reading.
•The ambient temperature of the scale should be kept as constant as possible. Do
not place the scale where it may be subjected to draughts or heater and direct
sunlight. It is advisable not to place the scale near windows, air conditioning vents
or radiators.
•The scale should be placed in a location where it is not likely to be damaged by
accidentally dropping heavy weights or moisture on to the scale. The weighing
area should be kept clean.
•Clean the scale with a damp cloth whenever necessary. The bottom of the scale
should be cleaned with a dry cloth only. Never use chemical or abrasive products.
•It is a precision scale and all care should be taken to protect the scale from
vibration, humidity, temperature variations and dust.
4.0 SETTING UP THE SCALE

unit. After connecting the battery, it is to be inserted in the socket provided at the
back of the battery cover and then place the cover back in its original position.
