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:

4.10 Accuracy measurement
The user can control the accuracy of the device according to the given reference standards. The device is
supplied with standard plastic films. These can be used to test the measurement accuracy of the
instrument with the help of supplied calibration blocks. They can also be used to protect the sensor on
rough or hot surfaces. The measured value should be within the accuracy range specified in the operating
instructions. For example, if the accuracy is specified as ± 2% + 2 μm, the measurement result should be
between 47 and 53 μm when the Coating Thickness Gauge is used to measure a 50 μm film thickness
plastic film. Otherwise, the device must be calibrated.

USER MANUAL

4.11 Calibration
The instrument has been factory calibrated and a built-in self-test function performed before the
measurement. Therefore, it usually only needs to be tested before the measurement if the measured
value is 0 when measuring an uncoated metal. If this is not the case, a zero point calibration should be
performed.
4.11.1 Zero-point calibration
Press the and select "Zero Point Calibration" by briefly pressing and "000" will flash on the
screen. Then measure an uncoated substrate. When "0" is displayed on the screen, the zero calibration
is successful. After this process, the instrument can usually be reused for accurate coating thickness
measurements. Nevertheless, due to abnormal base materials or extreme environmental conditions,
additive errors may occur. If this is the case, you can use the standard plastic films to perform a multipoint
calibration.
4.11.2 Multipoint calibration
Use the instrument to place standard plastic films on a calibration block if the value found is outside the
accuracy limits of this manual. Lift the probe ("Pt1 ~ μm" flashes in the screen to "), press or
for fast scrolling) to set the value of the actual thickness. Repeat this with other plastic films. The use of
two of these standard plastic films is better for calibration than just one. For example, you can use a thin
and, alternatively, a thick foil. If the coatings to be measured are relatively close to the thickness of the
other, it is sufficient to use only a film of similar thickness for the calibration.

USER MANUAL

4.12 Factory settings
If zeroing with standard plastic films does not work, it may be necessary to reinitialize the device. First
press briefly select "Reset", then "Complete Reset" and confirm with
"Complete reset" will flash in the display and indicate together with a beep that the initialization is
completed. To ensure high measurement accuracy, it is recommended to perform a zero point calibration
after initialization. All previously saved values and settings are deleted after initialization and the device is
reset to factory settings.
Note: When measuring the coating thickness of alloys such as aluminum or stainless steel alloy, the
instrument must be calibrated as follows:
1. Turn on the coating thickness gauge, initialize it to factory settings, and turn it off.
2. Turn it back on and calibrate it to 6 standard slides (if accuracy was affected, keep the unit away
from any material during the entire calibration process).
