• Procedure for calibration
An application channel must be selected before calibrating. (Refer to p. 16 for setting)
• Once an application number has been set, the settings remain in memory until the procedure is
performed again, even if the unit’s power is turned off.
Select the method of calibration (Simplified or Multipoint) referring to p. 25. The Coating Thickness Tester is
preset to Simplified when sold.
• Examples of Zero Base and Calibration Foil Combinations
*

For 2000 µm calibration foil, use 500 µm and 1500 µm foils together.
* The furnished substrate is simply used to test the precision of the unit.
* The calibration foils’ values are not always those listed in the table above, but are closest to their actual measured
values. For calibration foils of other thicknesses, other than those furnished, please contact customer service.
