（４）Zeroing in special cases (Multi-layers)
Measuring the thickness of the 4
th
layer
by zeroing at the 3
rd
layer.
Coating films
In case of being painted as shown with multi-layers on the substrate there may be needs to measure thicknesses of
each layer. For example, measuring only the thickness of the 4
th
layer please zero as an assumed ZERO at the surface
of the 3
rd
layer stacked on the substrate.
◆ Releasing of special-case zeroing
When zeroing again on the substrate after having finished the above measurements and if the combined thickness of
3 coating layers from 1st to 3rd exceeds 50 μm, please zero the meter on the following procedures.
If the thickness of 3 combined layers is bellow 50μm, take the same procedure as usual zeroing to release.
● Prepare the identical material quality, plate size to a measuring object.
（This is a designated as a Zero Plate）
Press
ZERO key.
The buzzer emits a beeping sound. It stopes the LOCK function of LOCK/DELETE key
and changes to one data “DELETE ” function.
Press probe on the above ｢Zero Plate｣
while the message is indicated on the screen.
(for about 20 seconds )
The buzzer beeps, beeps, beeps.
