CAL - Two-Point Calibration

Use the uncoated substrate and the 1006 μm reference film or use two reference films (one
thinner than the other) of known thickness.
Remove the protective plastic coating from the metal reference standards before use.
Note: To clear previously set calibration points, while in the measuring mode, press and hold
ZERO/CLEAR for at least 2 seconds. The LCD will display "0000".
The maximum possible calibration value is 1006 μm (39.6 mils)

2. Press MENU to access the Two-point Calibration mode. 'CAL' will be flashing in the upper
right corner of the display.
3. Press MENU again and the LCD will display Lo in the upper right hand corner.
Use the up and down arrow buttons to set the value to '0' for an uncoated substrate or
to the thickness value of the thinner reference film being used for the calibration.
4. Press MENU/ENTER to confirm the value. The display will flash 'PUSH'.
5. Press the tip of the gauge to the uncoated substrate for '0' or to the substrate with the
thinner reference film. The gauge will beep once. The low value calibration point is now
set.
6. The LCD will display Hi in the upper right hand corner.
Use the up and down arrow buttons to adjust the display to the value of the thicker
reference film. Use the standard coating plate (1006μm/39.6mils) or a known reference
film that is thicker than the first calibration film.
7. Press MENU/ENTER to confirm the reading. The display will flash 'PUSH'.
