F Probe Description
Measures the thickness of non-magnetic materials (example: paint,
plastic, porcelain enamel, copper, zinc, aluminum, chrome, ect.) on
magnetic materials (example: iron, nickel, ect.). Common uses include
measuring thickness of galvanizing layer, lacquer layer, porcelain layer,
phosphide layer, copper tile, aluminum tile, some alloy tile, and paper.
N Probe Description
Measures the thickness of non-magnetic coatings on non-magnetic
metals. Common uses include measuring the layer of varnish, paint,
enamel, plastic coatings, or powder applied to aluminum, brass,
non-magnetic stainless steel.

LCD screen.
Select the measurement unit by pressing µm/mil button, which
will appear on the LCD screen.
Place the probe on a coating layer to be measured.
The LCD screen will display the thickness of the coating layer.
The reading can be corrected by removing the probe from the
layer and by pressing the plus or minus button.
To take another measurement, lift the probe to more than 1
centimeter and then repeat steps 5-7.
Turn the meter off by pressing the Power button. The meter will
also turn off after 2 minutes of inactivity.
