Auxiliary Functions; Correcting The Distance Display (Span Adjustment) - Omron ZX-T Operation Manual

Correcting the Distance Display (Span Adjustment)

This setting is used to correct discrepancies between the display value and the actual amount
of displacement. Set the desired distance (units: µ m).
This correction does not change the Sensor's reference position (distance display: 0 mm).
The correction range is about 2% of the measurement distance.
Example: ZX-TDS01T
Measurement distance: 1 mm, range of correction: 20 µ m
Example: Actual displacement: 0.5 mm, display value: 0.498 mm
The displacement discrepancy ranges from 0 to 0.5 mm and is 0.002 mm here.
In a range from 0 to − 0.5 mm, a discrepancy of 0.002 mm is about what you would expect. If the total
discrepancy is 0.004 mm (4.0 µ m), then set the correction to 4.0.

Correction details are registered in the Sensor Head. This means that once done, the correction will not have
to be redone even if the Amplifier Unit is replaced.
