Calibration
The REFSCALE-S is calibrated at the factory to provide high
accuracy. While recalibration should seldom, if ever, be
necessary, a field calibration is performed easily without sending
the product to the manufacturer for service. A known, stable
calibration weight (in kilograms) is required to perform the field
calibration of the scale, and can be any value between 10 kg and
100 kg. Best accuracy is obtained by using the largest weight
available.
The calibration must be carried out using standardized weights.
The REFSCALE-S must be placed on a firm, flat, level surface.
