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.

Wear-proof ruby probe tip for long-term use.
The device can identify the ferrous putty as well as the galvanized iron substrate.
Dual-use probe for both iron and aluminum. The gauge can automatically identify the substrate and switch measurement mode rapidly.
“Fe”, “NFe”, “Fe/NFe” three measurement modes can be set.
The gauge can measure the non-magnetic coating thickness on metal substrates and non-conductive coating thickness on non-magnetic substrates.
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.

Operation

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.
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.

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

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
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.
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.
Hold the probe still, long press the button for 3s, the gauge will display “zero reference place probe” (as shown in below picture).
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.
The zero adjustment completed when there is the buzzer sound again, and the LCD screen displays
0.0.
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.
Measurement
Use fingers to hold gauge where there is non-slip groove.
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.
To continue measuring, lift the gauge away from the object. Repeat the operation of step 2).
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”.
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.

APP Operation

The coating thickness gauge is equipped with built-in Bluetooth communication, which can be connected to the gauge through the mobile app

Mobile APP installation and use
Mobile APP installation: Scan the QR code on the cover with your cell phone’s browser or the system’s own scanning function, and follow the instructions to download and install coating thickness gauge software; iPhones can be installed by searching for ” Coating Thickness Gauge” in the App Store. After installation, the icon of “Coating Thickness Gauge” will appear on the desktop of your cell pho ne as shown in the picture below.
Connect the device: Open the APP. If there is no bound Bluetooth device, then enter the Bluetooth setting interface. Click “Start Searching”, prompt “Searching for device… ” and list the available Bluetooth devices that are searched; click the “Stop Searching” button to stop searching for Bluetooth devices. Selecting gauge serial number will bind the selected gauge (prompt: each gauge has a unique serial number). After the connection is successful, it will automatically enter into the main measurement interface and Bluetooth icon will be displayed at the bottom right of the gauge screen. If the APP has a bound Bluetooth device, automatically search and connect the bound Bluetooth device. When the connection is successful, it will automatically enter the “Measure” interface.

Precaution

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.
Some car bodies may be misjudged as iron-zinc car bodies due to the base material.
Do not slide the probe on the car surface, which will result in damage to the paint and the gauge.
Please keep the car paint surface clean, the dust and dirt on the paint surface will affect the measurement accuracy.
When the gauge displays low battery, the battery needs to be replaced.
