Measuring Principle
1) Magnetic method (F Probe)
Measuring Non-magnetic coatings on magnetic substrates (such as aluminum, copper, rubber coatings on steel, iron, alloy and hard magnetic steel substrates).
When the probe contact with cover,measuring probe and magnetic metal matrix form a closed magnetic circuit, as a result of the existence of a
nonmagnetic layer, make the magnetic circuit magnetic resistance change, can be derived by measuring the change the thickness of coating.
2) Eddy current method (N Probe)
Measuring Non-conductive coatings on Non-magnetic basis metals (such as enamel, plastic, rubber, paint coatings on copper, aluminum, zinc, tinsubstrates).
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.

Test
Power on the gauge. Press the probe steadily on a coating layer to be measured. The reading on the display is the thickness of the coating layer.
To take the next measurement, please lift the probe to more than 3 centimeter and then repeat the step above .
Note: Based on the testing principle of Magnetic / Eddy current ( Fe / NFe) , the speed of pressing the probe on the coating layer should be appropriate. If too slow, it will cause man-made testing errors.
Unit conversion
Switch between μm / mil : Long-press the power key (about 6 seconds) till "UNIT " showed on the display.
Test mode conversion
Switch between Single / Continuous: Long-press the power key (about 8 seconds) till SC showed on the display.
Note: Under Single test mode, the symbol 
appears only during measurement. Under Continuous test mode, the symbol appears all the time.
Power off
1, 2x1.5V AAA alkaline battery.
2, Long-press the power key for 2 seconds to turn off.
The gauge automatically turns off if no operation within 60 seconds.
3, Battery replacement
When the battery voltage less than approx. 2.3V , the battery symbol 
will appear on the display. Then, slide the Battery Cover away from the gauge and remove the batteries. Install new batteries correctly into the case.
Note: If the gauge is not to be used for any extended period, remove batteries off.
