Measuring Principle
This instrument adopts  eddy current thickness methods(NFe Probe):

Measuring Non-conductive coatings on Non-magnetic basis metals (such as enamel, plastic, rubber, paint coatings on copper, aluminum, zinc, tin substrates).
By using high frequency alternating current in the coil produces an electromagnetic field,when the probe contact with cover,Metal substrate eddy current is produced,and feedback to a coil in a probe,Derived by measuring the size of the feedback effect of the coating thickness.



1, Environment Requirement
Strictly avoid collisions, heavy dust, humidity, strong magnetic field, oil, etc.
2, Battery Replacement
2 AA batteries are installed in the tester.WhenLeeb211 NFe Probeand Coating Thickness Tester Switch Off Automatically 0 sign appears, please replace the batteries.
3, How to replace battery:
Open the cover of the battery compartment when the tester is off, take out the empty batteries and fill in the new ones.
Date and time and measuring conditions need to be reset after replacing the batteries.
4, If you do not show the error code and don't work properly, such as:
a)  Does not automatically power off
b)  Can't measure;
c)  Button doesn't work;
d)  Measured values capricious.
     Appear this kind of failure, when the user through the above method is still can't rule out failure, the user, please do not dismantle machine repair themselves.Fill in the warranty card, please deliver instrument maintenance department, perform the warranty regulations.
If the error can be simple to describe, sent out together, we will thank you very much.

Five calibration specimens (48.5μm,99.8μm,249μm,513μm,1024μm)
