1 Introduction
Thank you for purchasing a CP Instruments Coating Thickness Gauge.
This hand-held device for coating thickness measurement with a separate probe is a highly intelligent and
accurate measuring device with which layer thicknesses can be measured quickly and accurately on
almost all metal surfaces. The instrument not only displays the film thickness but also automatically
identifies the metal base (Fe stands for magnetic metals such as iron and steel, nFe denotes non-
magnetic metals such as aluminum, metal alloys and non-magnetic steel). With the device different
coatings can be measured:
non-magnetic coatings, ceramics, enamels, plastics, rubber coatings;
magnetic base materials such as iron or steel, non-ferrous metals such as nickel and
chromium;
corrosion protection coatings in the chemical and oil industries;
non-conductive paints;
plastic coatings and anodised coatings on non-magnetic conductive devices such as aircraft,
household appliances, vehicles, completely alloyed doors and windows, as well as other
aluminum products;
electrically conductive coating material.
Specifications and prices of all CP Instruments devices can be found on our website:
http://www.cp-instruments.pl. You will also find our contact details there. Our staff will gladly help you
with any questions.

4.3.2 Continuous measurement
The CO mode is the measuring mode of continuous measurement:
Press the probe vertically against the surface to be measured. The instrument will beep continuously and
display the coating thickness reading when the readings have been taken.
Note: During the measurement, do not lift the probe off the surface to be tested until the measurement is
complete. The screen will be displayed in the next picture:
4.4 Measuring range
The device measures layer thicknesses between 0 μm and 1250 μm. If the thickness is outside this range,
"---" will appear in the display. The screen will be shown in the next picture:
