Calibration and Adjustment
Background During calibration, a calibration weight is used to determine how much the
displayed value deviates from the actual measurement value . This deviation is
compared against a preset target value . The subsequent
adjustment corrects
this deviation or reduces the permissible error limits .
Calibration and adjustment are combined in one process in the moisture analyzer .
After each calibration the analyzer is automatically adjusted .
When and How Often The moisture analyzer must be calibrated and adjusted, for example:
– When the ambient conditions have changed (temperature, humidity, or air
pressure)
– When the moisture analyzer is set up in a different location or moved in its
current location .
An external calibration weight is required for calibration and adjustment (100 g) .
Please note the tolerance of the calibration weight being used .
