2.3.4 Working in «CALIBRATION» mode
To ensure that the measurement error meet the value in the datasheet during the testing of coating,
user should set the device according to properties of substrate and coating.
Warning!
The factory settings of the device correspond to the following:
– for inductive probes F and parametric probes M – dielectric coatings on Page 3 (P. 10. P.20. P.
30. P45);
– for parametric probes NF – dielectric coating on aluminum D16T (D16, AmG6, AK6).
Note – It is recommended to create a backup copy of the calibrations before calibration to resume
proper calibration in the event of incorrect settings. (c. 2.3.7).
When entering the «Calibration» section, the table like on fig. 2.12 will be displayed, where each
cell corresponds to the base material of calibration (Ferromagnetic base, Non-ferromagnetic base, Base
1, Base 2) for a specific material of coating (Dielectric coating, Coating 1, Coating 2, Coating 3, Coating
4).
The calibration cells have three conditions:
– Calibration;
– Custom graduation;
– Empty cell.
Figure 2.12 – «CALIBRATION» section
Using the buttons «
» and «
»,
select the cell for calibration, then by pressing «
»
enter «menu» of calibration (fig. 2.13), and press «EDIT».
Figure 2.13 – Calibration menu
Prepare a sample for calibration, for which on the base firmly lay a coating measure with a nominal
value. Set the probe on the prepared sample and make at least 5 measurements. The device receives
nominal codes making measurements and the purpose of the calibration is to find the correlation between
the nominal code and the value of the coating thickness.
When the measurements are done, enter the nominal value by pressing «EDIT», and enter the actual
value of thickness by pressing «
» and «
» (fig. 2.14). To enter the next value, use «
