4. Measurement procedure
4.1 Press the power button lightly, and 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在确认校准正确的前提下，就可开始测量。若对以前的校准有所怀疑的话，应再进行一次校准。校准的具体方法详见仪器的校准部分。仪器一旦校准，校准结果将自动存贮在仪器中，下次开机测量时，可不必再次进行校准，除非对测量的准确性有怀疑。
4.3将测量传感器压紧到被测涂层上，显示器上的值即为待测涂层的测量值。
注意：由于所有的磁性涂层测厚仪都是采用电磁感应原理；非磁性涂层测厚仪采用电涡流的原理，因此一定要注意探头压上被测体的速度不能太慢。 否则会造成人为测量误差。
4.4要进行下次测量，需要将测量传感器提起到一厘米以上,然后再重复4.3。
4.5如有必要，测量值可通过加一键或减一键来修正。需要注意的是按加一键否或减一键修正时，测量探头一定提起，则按加一键或减一键无效。
4.6要更换测量单位，实现mm和mil的转换，只要轻按一下单位转换键即可。
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 After the measurement is completed, lightly press the power button to turn off the power of the whole machine. And apply a little grease on the contact of the measuring head and the reference block to prevent rust.
6.4 The instrument has an automatic shutdown function, if no operation is performed 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 of the probe.
7. Battery Replacement
7.1 When the battery voltage is about 2.5V, the battery symbol will appear on the display, 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 period of 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, use the optional "USB data line output", "RS232C data line output" and "Bluetooth Bluetooth data line output" to communicate with the computer to realize data collection, processing, analysis and printing and other functions. Please refer to the online instructions for specific operations, and install the battery correctly.
