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
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.
