Performing a THRU-COAT Calibration

The calibration procedure for a THRU-COAT probe is similar to the procedure for
other probes. As for a normal calibration, you need two uncoated samples with
accurately known thin and thick thicknesses in order to perform the calibration
procedure below. The difference is that towards the end of the procedure, you can
press [CAL VEL] a second time to calibrate the coating thickness measurement on a
sample with an accurately known coating thickness.
To perform a THRU-COAT calibration
1. Ensure that the THRU-COAT function is enabled (see "Enabling the THRU-
COAT Function" on page 76).
2. Couple the transducer to the thick sample.
3. Press [CAL VEL].
4. Once the reading is stable, press [ENTER].
5. Using the arrow keys, edit the thickness value to match the known thickness of
the sample.
6. Couple the transducer to the thin sample.
7. Press [CAL ZERO].
8. Once the reading is stable, press [ENTER].
