3. OPERATING INSTRUCTIONS
3.1 Hold the tester and make sure that it is at least 20cm away from the object to be tested and
other objects. Then press the 'TEST' button to turn on the tester. '- -' appears on the display
and flashes, then 'mm' appears.
3.2 Press the 'UNIT' button to select the desired unit - 'mm' or 'mil'.
3.3 Place the tester's probe perpendicular to the surface to be tested, the display will show the
coating thickness.
● If the display shows '- -', it means the tester does not detect any iron, steel or aluminium
substrate.
● If the display shows 'OL', it means that the coating thickness exceeds the tester's
measuring range.
● If the display shows ' - O', it means that the probe has wear or substrate under the coatings
or it may be of a metal other than iron, steel or aluminium.
3.4 When you measure, the reading will remain on the display, move the tester away and press
'TEST' to delete the reading, the display will show '- -'.
3.5 If it does not detect the presence of iron, steel or aluminium in about thirty seconds, it will turn
itself off automatically. To turn the tester off manually, press and hold down the 'TEST' button
for one second.
NOTE: If the temperature changes during measurement turn off the tester and turn it on again and
then make the measurement immediately. This will ensure measurement accuracy.
Different kinds of steel have different magnetic suceptibilities and conductivities, so the
measurement results of coatings on different kinds of steel (substrate) may be different, even
if these coating thicknesses are the same. For coatings on steel, measurement results can
only be used for non-critical reference.
4. BATTERY REPLACEMENT
When the low battery indicator appears on the display, the battery must be replaced immediately.
4.1 Make sure the tester has turned off, then rotate the battery cover in the direction indicated by
the arrows on the battery cover.
4.2 Tap the tester on your palm to remove the battery cover and the battery will fall out.
4.3 Install a new cell of the same type (3V button cell, CR2032 or equivalent), make sure the
positive terminal of the button cell will face the battery cover when the cover is installed.
