4. Measurement procedure

4.1 Press the power button lightly, after turning on the power of the whole machine, the instrument will automatically enter the measurement state, and automatically restore the parameter settings before the last shutdown.

4.2 After confirming that the calibration is correct, the measurement can be started. If there is any doubt about the previous calibration, another calibration should be performed. The specific method of calibration is detailed in the calibration part of the instrument . Once the instrument is calibrated, the calibration results will be automatically stored in the instrument, and the next time the instrument is turned on for measurement, it is not necessary to calibrate again unless there is doubt about the accuracy .

4.3 Press the measurement sensor onto the coating to be tested, and the value on the display is the measured value of the coating to be tested.

Note: Since all magnetic coating Thickness Gauges use the principle of electromagnetic induction; non-magnetic coating Thickness Gauges use the principle of eddy current, so it must be noted that the speed of the probe pressing on the measured object should not be too slow. Otherwise, it will cause artificial measurement error.

4.4 For the next measurement, you need to lift the measurement sensor to more than one centimeter, and then repeat 4.3.

4.5 If necessary, the measured value can be corrected by adding or subtracting one key. It should be noted that when the plus or minus key is pressed to correct, the measuring probe must be lifted, and the plus or minus key is invalid.

4.6 To change the measurement unit and realize the conversion , just press the unit conversion button lightly.

4.7 要更换测量模式，实现单次测量和连续测量的转换，只要轻按电源键不放，直到显示器上出现“SC”才松开按键（从按下电源键到出现“SC”大约需要9秒钟）。然后，再按一下 ZERO 键即可。若显示器上有符号 ，表示测量模式为连续测量，测量时蜂鸣器不响。否则为单次测量模式，每测量一次蜂鸣器都响一下。

4.8 测量完毕, 轻按电源键关断电源。本仪器设有两种关机方式，即手动关机和自动关机。在任何时侯，只要轻按一下电源键，就可手动关断整机电源；另一方面，若在50秒钟的时间内，未按动任何按键，则会自动关机，以实现省电功能。

5. 仪器校准

将测量探头压在基准块上（或不带涂层的测量体上），再轻按一下电源 / 校零键进行校零。在按电源/校零键时， 测量探头在基准块上不要晃动。同时要注意，只有在按完电源 / 校零键后，才能提起探头，否则，校零不正确。

6. 注意事项

6.1 基准块的选择原则：基准块的选择要与所选择的探头一致。当选择铁基 NF 探头时，基准块要用铝基.

6.２为了减少测量体材质对测量精度的影响 ， 建议采用不带涂层的测量体或与测量体材质相同的标准试块作为校准用基准块。

6.３测量完毕，轻按一下电源键，关断整机电源。并在测量头的触头及基准块上涂少许油脂以防生锈。

6.4 The instrument has an automatic shutdown function, if no for about 50 seconds, it will automatically shut down.

6.5 The instrument should be protected from severe vibration and impact. After use , wipe off the oil on the surface of the instrument and put it in the instrument box for safekeeping .

6.6 It is strictly forbidden to knock or collide with the probe so as not to affect the performance .

7. Battery Replacement

7.1 When the battery voltage is about 2.5V, the battery symbol will appear , and the battery needs to be replaced.

7.2 Open the battery cover and take out the battery.

7.3 Install the battery correctly according to the label on the battery box .

7.4 If the meter will not be used for a long time , please take out the battery to prevent the battery from rot and damage the meter .

8. Computer connection

8.1 According to the label on the battery box, the optional "USB data line output", "RS232C data line output" and "Bluetooth data line output" can be used to communicate with the computer to realize data collection, processing , analysis and Printing and other functions. For details, please refer to the

According to the instructions of the machine, install the battery correctly.
