5 Calibration and Maintenance
5.1 Calibration
For ensuring measurement accuracy, you may need
calibrate to correct the error caused by wear and tear or
changes in environment etc..
Press to enter the menu and select Measure, press
to select Calibration, you can enter the instrument
calibration interface.
Three calibration methods are provided: Zero calibration
(Zero), One-point calibration (1st) and Two-point
calibration (2nd).
NOTE: Before One-point calibration zero calibration must be
carried out. Before the Two-point calibration, the
Zero-calibration and One-point calibration must be carried out.
12
Fig 5-1
5.1.1 Zero Calibration
Zero calibration may be in two ways: Zeroing and Menu
zero calibration.
1) Zeroing
a) In single mode, measure on the substrate directly,
display the results "xx μm";
b) Press to clear display as "0.0 μm".
NOTE:
i) If "xx μm" is greater than 80μm, ou cannot zero it directl ,
Menu zero calibration is needed.
ii) Repeating the above a), b) as a few times ma increase the
accurac of the calibration.
2) Menu Zero Calibration (Fig.
5-1)
a) Enter Menu and select
Calibration, then select Zero (zero
calibration), press , wait for
showing Acting;
b) Measure on the substrate
directly, measuring 3 to 5 times or
more can ensure accuracy;
c) Press to save the
calibration values and remain in the calibration interface.
Then press can finish the Zero calibration and return;
d) If press only, will be not save the calibration and
return.

5.1.2 One-point calibration
Before One-point calibration
perform, must first do
Zero-calibration.(Fig. 5-2)
a) Press to select the 1st
(One-point calibration), "0000.0"
will be shown;
b) Press to enter the standard
value of foil;
c) Press to adjust the value,
press to move to the next
digit, Input the standard thickness
value of the foil, (press to
return to the initial setting value).
Then, press and waiting for
showing Acting;
d) Measuring on the standard thickness foil for 3 to 5
times;
e) Press to save the calibration values and remain in
the calibration interface, you can proceed to the next one
calibration;
f) Or press to not save the calibration and return.
5.1.3 Two-point calibration
Before Two-point calibration, first the Zero-point
calibration and the Two-point calibration must be done.
And thickness of the standard foil must be greater than in
14
Fig 5-3
the One-point calibration.(Figure 5-3)
a) Press to select the 2nd (Two-point calibration),
"0000.0" will be shown;
b) Press to enter the standard value of foil;
c) Press to adjust the value, press to move to
the next digit, Input the standard thickness value of the
foil, (press to return to the initial setting value). Then,
press and waiting for showing Acting;
d) Measuring on the standard
thickness foil for 3 to 5 times;
e) Press to save the
calibration values and remain in
the calibration interface, you can
proceed to the next one
calibration;
f) Or press to not save the
calibration and return.
5.2 Maintenance
1) Avoid dirt, dust, humidity,
corrosive substances of chemical
environments. Prevent the
instrument has been dropped!
2) After use, place the instrument back into the protective
device.
15
3) Avoid strong sunlight and temperature fluctuations,
which would adversely affect the measurement results.
4) The instrument enclosure resistant to most chemical
cleaners, use a soft cloth to clean the instrument.
5) Only keep it clean probe to measure the accurate results,
so the probe regularly inspect and clean them paint, iron
and other residues.
6) Standard thickness foil is very important in the calibration.
So if the standard pieces appear worn, bent or damaged,
contact your dealer to replace.
) If the gauge is not working, please do not disassemble it.
Should send it to the professionals or back to the factory for
repair.
