Precautions for the weighing operation
Press the RE-ZERO key each time, before placing a sample on the weighing pan, to prevent
possible errors.
Place a sample in the center of the weighing pan gently.
Temperature changes during measurement may cause weighing error.
Shorten the operation time as much as possible. (
Opening and closing door, putting and removing sample)
Material with an electrostatic charge or that is magnetic may cause a weighing error.
Use a pair of tweezers to avoid a temperature change due to having your hand in the weighing
chamber.
Do not drop things on the pan, or place a weight on the pan that is beyond the weighing range.
Keep the area clean and dry.
Do not press keys with a sharp instrument (such as a pencil or ball point pen).
For precision weighing, keep the AC adapter connected to the balance.
Calibrate your balance periodically to maintain weighing accuracy. Refer to section "8. Calibration".
For BM-22 and BM-20, perform pre-weighing of tare (and container) so that precision weighing
can be performed.
Consider section "3. Precautions" for the weighing operation.
