Operation

Power on/off

1. 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.

2. 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.

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, there are Fe plate and NFe plate, please choose correctly according to the measuring materials.

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.
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. 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.
4. The zero adjustment completed when there is the buzzer sound again, and the LCD screen displays 0.0.
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.

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: “Ferro us 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

Attentions

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. Some car bodies may be misjudged as iron zinc car bodies due to the base material.
3. Do not slide the probe on the car surface, which will result in damage to the paint and the gau get
4. Please keep the car paint surface clean, the dust and dirt on the paint surface will affect the measuremen t accuracy.
5. When the gau ge displays low battery, the battery needs to be replaced.
