ZERO SETTING
The following instructions allow you to
set the zero on the instrument:
1) Switch the level on and select the lo-
wer scale (A). Then with the potentiome-
ter on the right, look for the zero. Then
verify the zero on the higher scale (E).
2) Turn the level of 180°, read the value
on the display and adjust the potentio-
meter untill when you reach the half of
the read value. (Example: if you read 26
µm in the position (a), adjust the poten-
tiometer to 13 µm on position (b)).
3) Repeat the same steps (1+2) by tur-
ning the level of 90°, as shown hereun-
der.
The instrument is now ready for use.

MEASURE SCALES
The instrument allows you to work with
five different measure scales, as follows:
Scale A
= 1 div 250 µm/m
Scale B
= 1 div 50 µm/m
Scale C
= 1 div 10 µm/m
Scale D
= 1 div 5 µm/m
Scale E
= 1 div 1 µm/m
div = division
