6-3 CHECKING PROCEDURE
The measurement acquisition may be checked
with the test-block :
1- Dampen the probe extremity with water and
place it perpendicular on the Pocket-II
test block like indicated below.
2- Press “MEAS”.
The acquisition should be fast : if necessary,
change slightly the position of the probe to
obtain an acquisition. You ear a repetitive
sound while the position of the probe
is incorrect.
You must be perpendicular
like the opposite diagram.
Note : Make a series of
measurments to have
a representative Standard Deviation (SD).

3- Results of the test :
if the procedure has been succesfull and the
position of the probe is correct, the readings
of the series of measurements must be
repetitive to ± 20 µm.
As some microns represent a very thin
thickness, some parameters influencing the
test-block itself :
- the variation of the thickness with the
ambiant temperature.
- possible dust.
- Incorrect positioning.
If you suspect any problem, please call for
Service.
