Using Factory Calibration; Testing & Validating The Gauge Calibration - Elcometer 500 Guia Del Usuario

10 CALIBRATING YOUR GAUGE (continued)
1 Press Menu/Calibration/Cal Method and select 'Coating Material'
followed by 'User Materials' or 'Generic Materials'. If the coating
material required is already selected, simply press
Menu/Calibration/Calibrate.
The calibration method currently selected is

indicated by the icon to the right of the display.

2 Use the

required coating material followed by
'Select' (Figure 19).
The gauge is calibrated using the
sound-velocity of the coating material
selected which is then displayed to the right
of the measurement screen, below the
calibration method icon, with the coating
material list index number above (Figure 20).
Pressing 'Escape' at any time will exit the
calibration procedure without calibrating the
gauge.

10.6 USING FACTORY CALIBRATION

Press Menu/Calibration/Factory Calibration to restore the default
factory calibration sound-velocity setting of 2390m/s (approximately
0.0941in/µs), the sound-velocity of a typical epoxy coating.
10.7 TESTING & VALIDATING THE GAUGE CALIBRATION
This feature allows the user to test and validate the gauge calibration
by taking a reading on a sample with a coating of known thickness,
without the reading being saved.
To test and validate the calibration:
1 Press Menu/Calibration/Test Calibration.
2 When prompted, apply couplant to the coated sample.
If a sample with a coating of known thickness is not readily available, one can

be created using the Elcometer 500 Coating Calibration Mould (CCM), see
Section 11 on page en-22.
