Basic Calibration Correction
Basic calibration in the following cases, the change is necessary:
-The probe frayed at the top.
-Replace a new probe.
-Special purpose.
In measuring, if error is clearly beyond the scope, should be made
for the
properties of the probe to the calibration is called basic
calibration.
By entering the six calibration values (a thickness of zero and
five values), can realign the measuring head.
Steps of basic calibration;
Step 1: Under normal condition, continuous press “Clear” three
times;
Step 2: Press“Menu”and up & down key to
select“Calibrate”,press“Menu”to into the correct Zero;
Step 3: Place the probe vertically in the middle of the matrix and
hold still; after completion of shows such as 5 seconds away
again.To the next.
Step 4: When show the“S1”(The first specimens),put the minimum
value (48.5 μm)specimens on the standard substrate,probe vertically
on the S1 hold still,
such as display again after 5 seconds.Display real thickness“Real
thickness(0049.4μm)”,press“Menu”and up & down key to select to
enter the value
from“(0049.4 μm)”to the real one“(0048.5 μm)” and go to the next;
Step 5: Display“S2”,remove“S1”,put ( 99.8μm)piece on the standard
substrate,probe vertically on the S2 hold still, such as display
again after 5 seconds,display“real
thickness(0096.7μm)”,press“Menu”and up & down key to select to
enter the value from“(0096.7 μm)”to the real one“(0099.8um)”and go
to the next;
Step 6: Use“Step 5”to complete the real value calibration
of“S3(249μm),S4(513μm),S5(1024μm)”
Step 7: After calibrate S5will display“Loading...”,about 2 seconds
later it will come back to boot interface.Measured again after 5
seconds, such as standard substrate(Or you will enter the
continuous mode),correct Zero to ensure that the display value to 0
after the test piece (or measured values are not accurate). The
basic calibration complete.
Note:Specimens with other basic calibration, on the specimens of each
thickness should be at least 1.6 times the thickness of a
specimen.Such as:20,50, 100,250,500μm.
After the calibration, the instrument will work according to the
new calibration value.
