四、仪器介绍

ZAPPITEC mod.12Z利用最新的技术进步提供一种不需要特殊培训的设备，可以对非铁磁性金属的电导率进行非破坏性，快速和精确的测量，尤其是用于输变电设备金属监督项目中铜排导电率测试，用于熔断器导电片电导率的测试。

The Portable Eddy Current Conductivity Meter ZAPPITEC mod. 12Z takes advantage of thelatest technological advances to provide an equipment that does not require special training，allowing non-destructive, quick and precise measurements of electrical conductivity innon-ferromagnetic bls.

五、仪器特点

电导率测量是以非破坏性方式检查金属纯度的非常宝贵的工具。

它还用于根据其导电性或热处理对不同的合金进行分类，并且也可在航空航天系统监测铝合金在许多应用中的热处理和热损伤，它也可以用来评估金属和合金的热导率。Conductivity measurements are an invaluable tool to check in a nondestructive way the purityof bls. It is also used to sort different alloys according to its conductivity or heat treatmentand to monitor heat treatment and heat damage in aerospace aluminium alloys among manyother applications. It can also be used to buate thermal conductivity in bls and alloys.

The Conductivity Meter model 12Z has two context-sensitive buttons and a high resolution LCDdisplay. The function of each button is shown in the lower part of the display. When notmeasuring conductivity the display shows the temperature of the probe in °C.

12Z有两个上下相关按钮和一个高分辨率LCD显示器。每个按钮的功能显示在显示屏的下部。当不测量电导率时，显示屏会以°C显示探头的温度。

The leftmost button turns the instrument on and off and the central button perbs Calibration( Cal ).最左边的按钮打开和关闭仪器，中央按钮执行校准（Cal）。

六、仪器功能

The model 12Z has the following special features:

12Z具有以下特殊功能：

➔Automatic 1 point Calibration自动1键校准

The conductivity values of standards shipped with the instrument are recorded initsnon-volatile memory. To calibrate, just place the sensor against the standardand press "Cal". The 12Z will now be calibrated around that conductivity value.The instrument can only be calibrated with the standards supplied with the unit.

仪器附带的标准电导率值记录在非易失性存储器中。要进行校准，只需将传感器对准标准并按下“Cal”即可。现在12Z将在该电导率值附近进行校准。

➔Lift-off compensation and measurement提升补偿和测量

The 12Z provides the user with lift-off measurements which can be used tobuate coating thickness or surface condition. It allows to accuraby measureconductivity even in rough "as-cast" surfaces.

12Z为用户提供剥离测量，可用于评估涂层厚度或表面状况。即使在粗糙的“铸造”表面，它也可以准确测量电导率。

➔Low power operation低功耗操作

The unit is powered by four "AA" alkaline batteries which provide around 100hours of continuous measurement. The auto-shut-off system extends battery lifeby turning off the unit if it is not being used. Replace all four batteries immediabywhen the battery indicator shows an empty battery.

本装置由四节“AA”碱性电池供电，可提供大约100小时的连续测量。自动关闭系统通过关闭设备来延长电池的使用寿命。电池指示灯显示空电池时立即更换所有四块电池。

七、仪器工作原理

Principle of operation  工作原理

12Z传感器产生一个高频磁场（60kHz），它在要测试的大部分样品中感应出涡流。传感器和样品之间不需要接触，可以进行真正的非接触式测量。这样可以通过非导电涂料（如油漆或表面氧化物）进行精确测量。

A high-frequency magnetic field (60kHz) is generated by the 12Z sensor which induces eddy currents in the bulk of the sample to be tested. There is no need of contact between the sensor and the sample, allowing true non-contact measurement. This allows precise measurements through non conductive coatings such as paints or surface oxides.
