The device consists of the processing unit (4) and probe (10) connected via socket (7). The socket
for probes (7) is located on the top part of the body. The keyboard (3) is located on the front panel, as
well as the graphic display (2). The battery compartment (5) is located in the back lower part of the
device, and the batteries themselves.

– navigation up in the device menu/selection of the measuring unit;
– navigation down in the device menu/selection of dimensions of the measuring unit;
– selection of operating mode;
– the probe zeroing.
1.6 Design and functioning
The device functioning depends on the probe used.
When the parametric probe is used (NF, M, DSH), the functioning is based on the measurement of
the generator that includes the coil of eddy current parametric probe. The generation frequency depends
on the coating thickness. The measured frequency is converted into the thickness value and shown on
the graphic display.
When the induction probe is used (F), the current impulse is generated in the primary coil of the
probe by the command from the controller. The electromotive force (EMF) is generated on the secondary

RDC.OD.TP-2020.000 OM
Operation manual
Coating Thickness Gauge NOVOTEST TP-2020
Page 10
coil. The generated EMF (the function of thickness) goes to the controller and is converted into the
thickness value. The coating thickness shows on the display.
Measurement accuracy
The measurement accuracy depends on the right consideration of the physical properties of the test
object and its homogeneity, temperature, roughness, surface geometry, and other parameters. The error
is specified for each probe in the tab. 1.2.
Operating mode
The device has a specific operating mode for each probe, and two modes common for all probes:
single measurement, and measurement with averaging.
1.7 Measuring units, tools, and accessories
The performance of the device is assessed by checking the modes of its operation and checking the
possibility of measuring the thickness by the thickness blocks (reference blocks). The discrepancy
between the readings of the device should not exceed the permissible error (tab. 1.2). If a permissible
error is exceeded, the device should be calibrated under c. 2.3.8.
The adjustment and setting of the device in case of malfunction shall be performed by the
manufacturer.
1.8 Marking and sealing
The device has the sealing established by the manufacturer.
The symbol of the device with the trademark of the manufacturer is applied to the front panel of the
device. The serial number is printed on the back panel.
1.9 Packaging
The electronic unit and the probe are delivered in a package (case), excluding their damage during
transportation.
To avoid mechanical damage to the cable and connectors of the device, disconnect the probe from
the device before placing it in the packaging container.

2.3.3 Zeroing of the probe
If operating conditions change (the ambient temperature changes considerably), the electrical
conductivity of the base material changes, or if the probe is switched on for the first time, the probe
should be zeroed. To do that, do the following steps:
1. Prepare an uncoated sample of the test object or structure, similar or close by geometric and
electrical properties, type of machining, or design of the tested part.
2. Then, set the probe on the prepared sample or object without coating upright, and push it down
(fig. 2.11) without wiggling.
Figure 2.11 – Setting of the probe on the uncoated object
Warning!
Do not move the probe along the test object (scan) during the measurement.
3. When the device will make measurement and the sound signal will be generated, remove the
probe from the test object. The display will show the measurement result.
4. Then, press the button « », and the display will show the message: 0.000 (00.00; 000.0; or
0, depending on the type of probe and selected value).
5. Check the accuracy of the zero setting, by re-testing the product without coating. The readings
should be in the range from 0 to 2 µm.
6. Then, make a measurement on the reference block from the kit. The device readings shall
correspond to the thickness of the used block, with consideration of the permissible error. If the
device reading, calibrate the device according to c. 2.3.3.

To enter the working mode with the automatic averaging of the measurement results, set the
«AVERAGE» mode in «SETTINGS» section. Now, the necessary number of measurements can be
done, and after each measurement, the device will calculate the average value and show the readings on
the display.
To remove the current measured value, press « », and the menu of selection of actions will be
opened (fig. 2.27), where you should choose «DELETE» parameter. The latest measurement will be
removed from the measurement series.

To completely remove the average value and start the new measurement series, press « » and
select «DEL ALL». Now, you can start the new measurement cycle with the average value.
To exit the measurement mode with averaging, set «CURRENT» in the «SETTINGS» section.
2.3.12 Measurement of the depth of cavities and roughness
The DSH probe works by the principle of a profile gauge. The measurement value displayed is the
distance between the measurement needle and the basic surface of the probe.
By setting the probe needle into cavities, pits, etc. their depth can be measured.
By making at least ten measurements along the line on the surface in the averaging mode (c. 2.3.11),
user can evaluate the roughness of this surface by Rz parameter.
To match the readings of the device with the actual ones when evaluating the surface roughness or
measuring the depth of the grooves, calibrate the probe on a polished base. The surface roughness must
be Ra 0.32 µm. The probe calibration provides for the zero setting, (c. 2.3.3).
To make measurement, do the following step:
1. Connect the DSH probe to the device (2.2.3).
2. Turn the device on (2.3.1).
3. Set the base material in the device settings – «Non-ferromagnetic base», and set the coating
material to «Dielectric coating».
4. Set zero on the polished base (Ra≤0.32 µm), under c. 2.3.3.
Measurement of the depth of cavity:
5. Set the probe on the prepared block or part upright and push it down without wiggling.
When the device makes a measurement, the sound signal will be generated, and the display will
show the measurement result (fig. 2.28).

6. To start a new measurement, lift the probe into the air, and another single signal will sound,
then the device is ready for a new measurement. The indicator shows the last measurement
result which changes only during the next measurement.
7. To turn the device off, press and hold « ».
Evaluation of roughness:
1. Enter the mode with averaging (c. 2.3.10).
2. Set the probe on the prepared block or part upright and push it down without wiggling.
3. When the device makes measurement, the signal will sound, and the display will show the
measurement result.
4. To start the new measurement, put the probe into the air. The display will show the latest
measurement result, changing only with the next measurement.
5. Make at least ten measurements along the line on the surface, and the averaged value will
indicate the roughness Rz.

2.3.13 Measurement of the air temperature, humidity, and dew point
The air temperature, air humidity, and dew point should be measured with the STMD probe.
To measure the air temperature, humidity, and dew point, do the following steps:
1. Connect the STMD probe to the device (c. 2.3.3).
2. Holding the probe by the handle (where parameters should be measured), make measurement
before turning the device on and holding « » button until the screensaver appears.
3. After turning on, the device will start measurements automatically.
4. The display will show the measurement results (fig. 2.29).

2.4 Connection of the device to PC
2.4.1 Software installation
Connecting the device to a PC, user can transfer the information stored on the memory card to a PC.
To connect the device to a PC:
1. Copy the driver «CP210x_VCP_Windows» and the program «AWP TP1M» (archives of .zip
and .rar format) to the hard drive of the PC or download the current versions from the official
website.
2. After downloading, unzip the data, and two folders will be obtained: driver and program (fig.
2.30).
Figure 2.30 – The downloaded software
3. Install the driver to PC.
Note – After notice about successful driver installation, it is advisable to restart a PC.
4. Now, user can connect the device to a PC by using the USB cable from the delivery set. After
connection, the computer will detect the new device and install the driver to use it.
5. Install the program to use the device, to do that, launch the program installation file (setup.exe)
from the folder «AWP TP1M», and press «INSTALL» (fig. 2.31).
