GB
The Coating Thickness Gauge Testboy
easy to carry. Although complex and advanced, it is convenient to use
and operate. Its ruggedness will allow many years of use if proper
operating techniques are followed. Please read the following
instructions carefully and always keep this manual within easy reach.
FEATURES
It meets the standards of both ISO2178 and ISO-2360 as well as DIN, ASTM
and BS. Suitable for the laboratory and for use in harsh field conditions.
The F probes measure the thickness of non- magnetic materials (e.g.
paint, plastic, porcelain enamel, copper, zinc, aluminium, chrome etc.) on
magnetic materials
thickness of galvanizing layer, lacquer layer, porcelain enamel layer,
phosphide layer, copper tile, aluminium tile, some alloy tile, paper etc.
The N probes measure the thickness of non- magnetic coatings on non-
magnetic metals. It is used on anodizing, varnish, paint, enamel, plastic
coatings, powder, etc. applied to aluminum, brass, non-magnetic
stainless steel, etc.
Automatic substrate recognition.
Manual or automatic shut down.
Two measurement mode:
Single and Continuous
Wide measuring range and high resolution.
Metric/Imperial conversion.
Digital display gives exact reading with no guessing or errors.

MEASURING PROCEDURE

Plug in the F-probe or NF-probe according to the measured body.
Press the power key to switch on the gauge and '0' displays on the Display.
The gauge will restore the state of last operation. The gauge can
recognize the probe itself with a symbol 'Fe' or 'NFe' indicating on the
Display.
Place the probe onto a coating layer to be measured. The reading on the
Display is the thickness of the coating layer. The reading can be corrected by
pressing the plus key or minus key while the probe is away from the
substrate or the measured body.
To take the next measurement, just lift the probe
to more than 1 centimeter and then repeat the step
If suspecting the accuracy of measurement, you should calibrate the gauge
before taking the measurements. For the calibration procedures, please
refer to the calibration part 5.
The gauge can be switched off by pressing the Power key. On the other
side, the gauge will power itself off about 50 seconds after the last
operation.
To change the measurement unit 'µm' or 'mil' by
depressing Power key and not releasing it till 'UNIT' on the Display and
