once, it will conduct tare function to return the LCD to zero. Then place new additional
object to the plate, LCD will weigh and indicate only the net weight of the added object.

object from platter, LCD will show the negative (-ve) value of the object being removed.
Note: Allowance for tare function = 0.8% of full capacity without reconciliation.

Maintaining and Cleaning (Proper Usage)
1. As the unit is a high precision device, it is very delicate and extremely sensitive.
Avoid dropping the unit or subject it to high impact which will greatly damage its
function and accuracy.
2. When operating the unit, please press the button slightly to activate function. Do
not exert too much force when pressing the button, or use sharp pointed object to
press the button.
3. Use a dry, soft fabric or a lightly damp soft fabric with mild detergent to clean the
device. Do not use strong chemical solution such as alcohol or benzene for
cleaning.
4. Avoid exposing the unit to high ambience temperature like near a cooking stove
or burning flame as it will cause the unit to degrade faster.
5. Do not expose the unit to high electro-magnetic field like cordless portable phone,
computer, transformer, etc. as this will interfere with the proper function of
electronics and accuracy of the scale.
6. Always weigh/use the scale on a hard flat surface. Do not use on carpets or mats.
7. Do not insert any exterior objects into any openings on the unit.
8. Remove the battery from the unit if not in use for a long time. Store in cool and
dry place.
