1 Pt Adjust
A 1-Pt Cal Adjustment, also known as an offset or correction
value, can be performed in five ways:
(i) Simple Zero Adjustment- Measure the uncoated part. Lift the
probe and adjust to "0" using the
NOTE:
A Simple Zero Adjustment cannot be performed when
Calibration Lock is enabled (default). Disable Calibration
Lock (pg. 5) to perform this adjustment.
(ii) Average Zero Adjustment
to (i) is to average 3 to 10 measurements on the uncoated part.
(iii) Simple Adjustment to a Known Thickness- Measure a shim
of known thickness placed on the uncoated part. Lift the probe
and adjust to the shim thickness using the
NOTE:
A Simple Adjustment to a Known Thickness cannot
be performed when Calibration Lock is enabled (default).
Disable Calibration Lock (pg. 5) to perform this adjustment.
(iv) Average Adjustment to a Known Thickness
A preferred method to (iii) is to average 3 to 10 measurements
of a shim of known thickness placed on the uncoated part.
(v) Zero Offset- Useful when measuring coating thickness over
rough or blasted substrates without access to the uncoated
representative substrate. Predefined Zero Offset values can be
selected according to the blast profile height in accordance with
ISO 19840. Alternatively, a custom Zero Offset can be entered.
The Zero Offset value is subtracted from each reading.
NOTE:
If the uncoated representative substrate is available,
performing an Average Adjustment to a Known Thickness
(above) is recommended for best accuracy.
2 Pt Adjust
Provides greater accuracy within a limited, defined range.
Measure known coating thicknesses that are thinner (often zero)
and thicker than the expected thickness range.
