    7. Various settings When the [SET] key is pressed on the measurement screen, the following menu screen will be displayed. For each function and operation method, refer to the reference page described as (P. ○○). * Once each function is set, the setting content will be kept intact even after the power is turned off until it is changed.
  • Page 15 1 Substrate calibration At the time of measurement, even if the type of coating is the same, the measurement value may be affected by the material and shape of the substrate (the same as the one to be measured, with no coating such as plating or painting on the surface). Perform a substrate calibration to correct the effect of the substrate before measurement. Once the substrate calibration is registered, it will be stored in the application (→P.20).
  • Page 16 2 Foil calibration Foil calibration is always required before measurement to obtain correct measurement values with the coating thickness tester. First, prepare a "substrate" that has the same material, shape and thickness as the object to be measured, and to which no coating such as plating or painting is applied.
