I. Product introduction
The coating thickness gauge is professionally used for measuring the
thickness of car paint. The car body shell material is generally metal
materials such as iron, aluminum and non-metallic materials such as
carbon fiber, plastic, etc. This coating thickness gauge can measure the
thickness of car paint on iron and aluminum materials. Moreover, it can
identify not only non-metal car bodies, but also the ferrous putty layer as
well as the galvanized iron. The gauge uses two low temperature
resistant OLED screens as display devices to ensure that the display is
still normal in a low temperature environment of -40°C. The measured
data will be displayed on the front and top of the gauge. When measuring
various positions of the car body at different measurement angles, it is
convenient to view the test data.

using different measurement angles.
6. Wear-proof ruby probe tip for long-term use.
7. The device can identify the ferrous putty as well as the galvanized iron substrate.
8. Dual-use probe for both iron and aluminum. The gauge can automatically identify the substrate and
switch measurement mode rapidly.
9. "Fe", "NFe", "Fe/NFe" three measurement modes can be set.
10. The gauge can measure the non-magnetic coating thickness on metal substrates and non-conductive
coating thickness on non-magnetic substrates.
11. Use advanced digital probe technology, these sensors are unsusceptible to interference and provide
an excellent measuring accuracy. Even temperature change will not affect measurement and data
remain stable to ensure a very good reproducibility over the complete measuring range.

IV. Operation
1. Power on/off
Power on:
Short press the power button to turn on the gauge. Display the version number and serial number, then
the recorded data of last measurement are displayed after the gauge is turned on.
Power off:
Long press the button to shut down the gauge, or the gauge will automatically shut down in 3 minutes
without any operation.
2. Device setting
In the off state, long press the button for 3 s to enter the setting interface. After entering the setting interface,
if there is no operation for more than 20 s, the instrument will automatically Shortly press the button can
select the settings; Long press the button for 3 s and less than 5 s to confirm the settings; Long press the
button for 5 s, the instrument exits the setting and shuts down and the setting is invalid.
Language settings
The instrument is available in Chinese, English, Russian, Turkish.
Setting method: In the main setting interface, short press power button to select "Language" option, long
press the button for 3 seconds to confirm the selection, short press the button again to select the desired
language, long press the button for 3 seconds to confirm the selection, and return to the main setting
interface.
Setting interface Language selection
Measurement modes selection
There are three measurement modes: Ferrous substrate measurement (Fe), Aluminum substrate
measurement (Al), and Auto identification (Fe/Al). Under normal circumstances, it is enough to use Fe/Al
auto identification mode. This mode features identification of the ferrous putty and galvanized iron
substrate. When the measurement substrate is settled, you can select Fe or Al as the fixed
measurement mode.
Setting method: In the main setting interface, select "mode" option by short pressing power button, and
long press the button for 3 seconds to confirm the selection. Shortly press the button to select the
measurement mode. And long press the button for 3s to confirm the selection and back to the main

setting interface.
Unit setting
The device can be set to the metric or imperial unit, and the factory default is metric.
Setting method: In the main setting interface, shortly press the button to select “Unit”. Long press the
button for 3s to confirm and then enter the unit selection interface. Shortly press the button to select your
unit and long press the button for 3s to confirm and back to the main setting interface.

Exit
In the main setting interface, short press power button to select "Exit", long press the button for 3
seconds to confirm and enter the measurement interface
3. Zero adjustment
A zero-adjustment is required when using the gauge for the first time, after inserting new batteries, working
with different materials or ambient temperature changes. Using iron-base and aluminum - base adjustment
plates respectively to carry out zero adjustment. We strictly recommend carrying out the reference check
on the uncoated original substrate, due to the difference of magnetic and conductive properties of the
material, some measurement deviation will be caused. If this is not possible, please use the zero reference
plates supplied by Linshang technology, there are Fe plate and NFe plate, please choose correctly
according to the measuring materials.
3.1 Measuring the plate or uncoated original substrate, a measured value will be displayed on the gauge,
please make sure the probe tip is placed perpendicularly and evenly on the surface.
3.2 Hold the probe still, long press the button for 3s, the gauge will display “zero reference place probe”
(as shown in below picture).

3.3 After hearing a buzzer sound, the gauge will display “Lift off probe at least 15 cm” (as shown in below
picture), release the button and lift the probe away from the plate (substrate) for at least 15 cm.
3.4 The zero adjustment completed when there is the buzzer sound again, and the LCD screen displays
0.0.
3.5 After the zero adjustment is completed, place the standard film on the plate (substrate), if the
measurement value is stable and deviation from standard value within ±3μm, the gauge can be used
normally.
Note: After the zero adjustment completed，when repeating measurement on the same spot, the
reading may not always be 0μm, since surface roughness, dirt, scratches etc. It might cause
variances. The operation of the gauge should be correct and proficient; otherwise, it will lead to
instability of the measured values.
4. Measurement
1) Use fingers to hold gauge where there is non-slip groove.
2) Press the gauge vertically on the surface of the object to be measured. Keep the gauge steady and
do not tilt or shake it. The result will be shown on the screen, and there will be a buzzer.
3) To continue measuring, lift the gauge away from the object. Repeat the operation of step 2).

4) When the device identifies the ferrous putty, the buzzer alerts for two times. And the interface of the
device will prompt: “Ferrous putty”. When the device identifies the galvanized iron, it will turn on the
green backlight. The substrate is displayed as “FeZn”.
5. Check measurement records
In measurement mode, short press the button to check historical data. The gauge stores 9 sets of data.
When more than 9 sets of data are stored, the earliest recorded value is automatically deleted, and No.1
is the last test data. Recorded data will not loss after powering off.
V. Precaution
1. The device must be zero adjusted respectively with the iron-base and aluminum-base zero adjustment
plates. Otherwise, there may be abnormal identifications of the ferrous putty and galvanized iron
substrate.
2. Do not slide the probe on the car surface, which will result in damage to the paint and the gauge.
3. Please keep the car paint surface clean, the dust and dirt on the paint surface will affect the
measurement accuracy.
4. When the gauge displays low battery, the battery needs to be replaced.
