7.3 USING MATERIAL CALIBRATION
The gauge is calibrated using the known sound-velocity of a
material as selected by the user from a pre-defined list stored in the
gauge. This calibration method is useful if uncoated sample test
pieces of known thicknesses are not available.
1 Press the On/Off button to switch the gauge on.
2 Press Menu/Calibration/Cal Method and select ‘Material’.
4
If ‘Material’ is already selected - the calibration method currently selected
is indicated by the icon to the right of the display - simply press

Pressing ‘Escape’ at any time will exit the calibration procedure without
calibrating the gauge.
4
The sound-velocity of the material selected will be displayed to the right
of the display, below the calibration method icon.
7.4 USING VELOCITY CALIBRATION
To calibrate the gauge using this method, the user must know the
sound-velocity of the test material. This calibration method is useful
if uncoated sample test pieces of known thicknesses are not
available.
1 Press the On/Off button to switch the gauge on.
2 Press Menu/Calibration/Cal Method and select ‘Velocity’.
4
If ‘Velocity’ is already selected - the calibration method currently selected
is indicated by the icon to the right of the display - simply press
Menu/Calibration/Calibrate.
é
3 Enter the known sound-velocity using the softkeys to
ê
select 0 to 9 and the
è
softkey to move to the next digit,
followed by ‘Set’ to use the value entered.
4
Pressing ‘Escape’ at any time will exit the calibration procedure without
