Product introduction

The coating thickness gauge is used for measuring the thickness of automobile paint. The gauge transmits the measurement data to the mobile phone APP in time through  Bluetooth. The mobile APP can record the paint thickness of different parts of the car and the corresponding shell material and can generate test reports. Test reports can be stored in image format and can be shared via QQ and We Chat.

Product advantages

1. No calibration, just zero adjustment.
2. One hand operation, only one button.
3. Fast measurement, 0.5s measuring interval.
4. Wear-proof ruby probe tip for long-term use.
5. The device can identify the ferrous putty as well as the galvanized iron substrate.
6. The gauge automatically identify the substrate and switch measurement mode rapidly.
7. “Fe”, “NE”, “Fe/NE” three measurement modes can be set.
8. Measuring non-magnetic coatings on steel or iron and measure Non-conductive coatings on nonmagnetic metal substrates  in one gauge.
9. Thanks to the use of the most-advanced digital probe technology, these sensors are unsusceptible to interference and provide an excellent measuring accuracy. Even  variations in temperature will not affect measurement and readings remain stable to ensure a very good reproducibility over the complete measuring range.
10. Built-in Bluetooth function, it can connect to the mobile APP and realize the whole automobile measurement data recording and generate the test report.

Operation

1. Power on/off
   Power on:
   Short press the button to turn on the gauge. Version number and serial number will be displayed and the gauge enter the last recorded historical data interface.
   Power off: Long press the button to shut down the gauge, or the gauge will automatically shut down in 3 minutes without any operation. When Bluetooth is connected,  the gauge will automatically shut down in 10 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 shut down. Short 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
   onfirm 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 with in the case, there are Fe plate and NE 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. 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 “Fez”.

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 won’t loss after powering off.
