4 CALIBRATION - BASE AND CAL
1. Press [BASE] for low end calibration on a zero plate or low value foil and [CAL] for higher foil.
If the password mode has been enabled (see “Password function” on page 20) then ‘- -’ is displayed
and the password will have to be entered.
2. Take a number of readings on the required calibration thickness. (Uncoated material for zero or base,
a thin foil for rough surface or unusual materials and a thick foil for cal).
(A wide range of foils is available - see “Foils” on page 38.)
The foil value shown on the label applies to a measurement position
as indicated:
The display will show an average value - indicated by the [ ]
symbol.
3. When the base or cal value shown on the display is stable, then
adjust the display to the required value e.g. ‘0’ or the foil value; enter
the required number using the keypad and then press [ENTER].
The ‘base’ or ‘cal’ symbols and [ ] will now be removed from the display.
If a base value greater than zero is entered, the rough surface symbol will be displayed.
This symbol will disappear from the display if the base is reset to zero (0).
