Calibration and Adjustment
The PosiTector PC is factory calibrated and performs an automatic
self-check each time it calculates a measurement. For many powder
measurement applications no further adjustment is necessary. Simply
Zero at the beginning of each shift, then measure.
Sometimes gage measurement calculations can be influenced by the
composition of the coating powder. A calibration adjustment improves
accuracy in these circumstances.
Adjustment, or Calibration Adjustment, is the act of aligning the gage's
predictions to match those of a known cured sample.
Begin by performing a Verification of Accuracy (pg. 6) to determine if
there is a need for an adjustment. If the average of several thickness
results is outside the combined tolerances of the two measuring
instruments (PosiTector PC and dry film thickness instrument) then 3
adjustment techniques are available to correct the variance.
User adjustments are stored in the current Cal setting. It may be
desirable to open a new Cal setting first (pg. 10).
