Total-Reset

A total reset erases data from all memories. This includes all sets of readings of all work modes plus their associated

statistics, calibration values and tolerance limits.

a) Switch off gauge.

b) Press ZERO+ simultaneously.

c) The LC display “sure to reset”, Press red-bar button for YES, or blue-bar button for NO.

d) The gauge will restart automatically.

e) If you want to cancel “NO”from the reset, press blue button.

Measurement view (menu item 5)

Via “Measurement view” in MENU, you can look through all measurement readings for current group.

Calibration (menu item 6)

There are three different methods available for calibration:

“Zero-point calibration”: recommended if measuring errors up to +-(3% of reading plus constant error of probe) are

permitted. (Example for constant of probe be error: Fe 1um; no-Fe 1.5um)

“One-point calibration” (calibrating using a calibration foil): recommended if readings to be expected will be close

to the calibration value and if the permitted error of probe will be max. +-(1%...3% of reading plus constant probe

error)

“Two-point calibration” (using a set of two calibration foils):

A ) Recommended for measurements on rough surfaces.

B) Recommended for precise measurements on smooth surface if the thickness to be expected lies between that

of the two calibration foils.
