Precautions for the weighing operation

Press the RE-ZEROkey 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)

Use a pair of tweezers to avoid a temperature change due to having your hand in the weighing chamber.

Material with an electrostatic charge or that is magnetic may cause a weighing error. Do not press keys with a sharp instrument (such as a pencil or ball point pen).

Do not drop things on the pan, or place a weight on the pan that is beyond the weighing range of the balance.

Calibrate your balance periodically to maintain weighing accuracy. Refer to section "8. Calibration".

Keep the area clean and dry.

Consider section "3. Precautions" for the weighing operation.

For precision weighing, keep the AC adapter connected to the balance.
