VII. Calibration
Calibration and adjustment are performed at the factory.
However, the weighing range can shift slightly during
shipping. Also, due to changes in local acceleration of gravity
around the world, adjustment is recommended when moving
the scale from one location to another. To check calibration:
1. Place the required calibration weight on the scale
and note the displayed value.
2. If the displayed value is not within acceptable
tolerance (see chart below), adjustment is required.
