Calibration

Calibration is a necessary step to assure the analytical balance will

accurately weigh the sample.

Perform calibration operations in the following situations:

•

Changes in the location of use (including moving in the same room).

•

Changes in ambient conditions.

•

Prior to each use.

The balance must be fully warmed up for one hour to stabilize the

weighing before calibration.

Procedure:

1. Press

“

TARE

”

to zero the balance in the weighing state.

2. Press the

“

CAL

”

button and the

“

CAL-200

”

flashing displayed.

3. Place the 200g calibration weight on the weighing pan.

4. Then

“

200.0000g

”

will be displayed. External calibration is completed.
