Because misoperation "▲"key or "▼"key causes the gauge not normally to measure.C. Measurement accuracy is degraded caused by environmental conditions changed greatly.10.2 How to restore?10.2.1 Press the um/mil key not release and then press the ON key, when the "8888" appear on the display, press ON key.The factory setting is restored.(10) Notes It is strongly recommened that no changes should be made to the value of Ln. Generally, the larger the value of Ln, the smaller the reading on a same thickness. A little variation of value of Ln will cause a great change in reading at high end (e.g. at 515um). The rules to adjust the value of Ln are as follow:A. Reading at low end can be adjusted to the exact value by the plus or minus key.B. To enlarge the Ln if readings at low end (e.g.at 50 um) is ok but reading at high end (e.g.at 388um) is too large. On the contrary, to decrease the Ln if reading at low end (e.g. at 51 um ) is ok but reading at high end (e.g. at 388um) is too small.C. Repeat procedures from A to B till the readings on the every standard foil are satifying the accuracy.(11) ServicesThis instrument has one-year quality guarantee, maintenance for all life. If there are any problem of this product, please contact the dealer in time. 8 一、概述本仪器采用磁性测厚方法，可无损伤地检测磁性金属基铁（如：铁、钢、合金和硬磁性钢等）上非磁性覆层的厚度（如：锌、铝、铬、铜、橡胶、油漆等）。

本仪器广泛地应用于制造业、金属加工业、化工业、商检等检测领域是材料保护专业必备的仪器1）本仪器符合以下标准GB/T 4956-1985 磁性金属基体上非磁性覆层厚度的测量（磁性方法）2）特点便携设计，手掌大小采用高速的DSP芯片，具有快速的测量能力人性化设计，简单操作在双用探头时自动识别铁基和非铁基材质，无需手动转换两种校准方式，零点校准和二点校准宽角度LCD液晶显示公制和英制单位转换具有电源欠电压提示操作过程有蜂鸣声提示具有自动关机功能3)测量原理磁性法当测头与覆层接触时，测头与磁性金属基体构成一闭合磁路，由于非磁性覆层的存在，使磁路磁阻发生变化，通过测量其变化量，可测得其覆层的厚度二、显示说明1 ● μm/mil 测量单位● CAL 校准提示● Fe 表示磁性基体测量状态NFe 表示非磁性基体测量状态● 8.8.8.8 测量厚度显示区● 电源欠电压提示三、使用说明1）开机按下ON键后仪器听到一声鸣响，屏幕上显示仪器测头模式自动恢复上次关机前的参数设置后，将显示0，仪器进入待测状态，可测量工件了经过一段时间不使用仪器将自动关机2）测量仪器会自动感应被测基体：感应到是磁性基体时仪器显示Fe；感应到是非磁性金属是仪器显示NFe。

测量时请始终保持仪器处于垂直状态！3）零位校准在待测状态下将探头垂直压在基准块上，之后屏幕上会显示<╳.╳μm>，然后按下“ZERO”键进行零位校准在上述过程中探头一直压在基体上，直到屏幕显示（0 CAL）后才能提起探头重复零校准可获得更为精确的零点注：因我们提供的Fe片和Al片的材质与贵司的基材不完全相同即零位并不一样，因此最科学的方法是在贵司实际工件光洁底材上做零位校准！ 2 Take the iron substrate if 'Fe' on the Display and take the aluminium substrate if 'Nfe' on the Display. Place the probe on the substrate steadily. Press the ZERO key and "0 CAL" will be on the Display before lifting the probe. If pressing the ZERO key but the probe is not placed on the substrate or an uncoated standard, the zero adjustment is invalid.6.2 Select an appropriate calibration foil according to your measurement range. 6.3 Place the standard foil selected onto the substrate or the uncoated standard. 6.4 Place the probe mildly onto the standard foil and lift. The reading on the display is the value measured. The displayed reading can be corrected by pressing the plus key or minus key while the probe is away from the substrate or the measure body. 6.5 Repeat step 6.4 until the result is correct.(7) BATTERY REPLACEMENT8.1 When it is necessary to replace the battery, the battery voltage is lower than 1.8V or The display reading changes darkly.8.2 Slide the Battery Cover away from the gauge and remove the batteries.8.3 Install two batteries (1.5V) correctly into the case.8.4 If the gauge will not to be used for a long time, remove batteries.(8) Considerations9.1 In order to weaken the influence of the measured material on the accuracy of measurement, it is recommended that the calibrations should be done on the uncoated material to be measured.9.2 Probe will eventually wear. Probe life will depend on the number of measureme。
