7 CALIBRATING YOUR GAUGE (continued)
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'.
If 'Material' is already selected - the calibration method currently selected

is indicated by the icon to the right of the display - simply press
Menu/Calibration/Calibrate.

3 Use the
by 'Select'.
Pressing 'Escape' at any time will exit the calibration procedure without

calibrating the gauge.
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'.
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.
3 Enter the known sound-velocity using the
select 0 to 9 and the  softkey to move to the next digit,
followed by 'Set' to use the value entered.
Pressing 'Escape' at any time will exit the calibration procedure without

calibrating the gauge.
The sound-velocity entered will be displayed to the right of the display,

below the calibration method icon.
