四、儀器介紹

ZAPPITEC mod.12Z利用最新的技術進步提供一種不需要特殊培訓的設備，可以對非鐵磁性金屬的電導率進行非破壞性，快速和精確的測量，尤其是用于輸變電設備金屬監督項目中銅排導電率測試，用于熔斷器導電片電導率的測試。

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 metals.

五、儀器特點

電導率測量是以非破壞性方式檢查金屬純度的非常寶貴的工具。

它還用于根據其導電性或熱處理對不同的合金進行分類，并且也可在航空航天系統監測鋁合金在許多應用中的熱處理和熱損傷，它也可以用來評估金屬和合金的熱導率。Conductivity measurements are an invaluable tool to check in a nondestructive way the purityof metals. 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 evaluate thermal conductivity in metals and alloys.

Conductivity of selected pure metals

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有兩個上下相關按鈕和一個高分辨率LCD顯示器。每個按鈕的功能顯示在顯示屏的下部。當不測量電導率時，顯示屏會以°C顯示探頭的溫度。

The leftmost button turns the instrument on and off and the central button performs Calibration( Cal ).最左邊的按鈕打開和關閉儀器，中央按鈕執行校準（Cal）。

六、儀器功能

The model 12Z has the following special features:

12Z具有以下特殊功能：

?Automatic 1 point Calibration自動1鍵校準

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.

儀器附帶的標準電導率值記錄在非易失性存儲器中。要進行校準，只需將傳感器對準標準并按下“Cal”即可。現在12Z將在該電導率值附近進行校準。

?Lift-off compensation and measurement提升補償和測量

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

12Z為用戶提供剝離測量，可用于評估涂層厚度或表面狀況。即使在粗糙的“鑄造”表面，它也可以準確測量電導率。

?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 immediatelywhen the battery indicator shows an empty battery.

本裝置由四節“AA”堿性電池供電，可提供大約100小時的連續測量。自動關閉系統通過關閉設備來延長電池的使用壽命。電池指示燈顯示空電池時立即更換所有四塊電池。

七、儀器工作原理

Principle of operation  工作原理

12Z傳感器產生一個高頻磁場（60kHz），它在要測試的大部分樣品中感應出渦流。傳感器和樣品之間不需要接觸，可以進行真正的非接觸式測量。這樣可以通過非導電涂料（如油漆或表面氧化物）進行精確測量。

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.
