安全注意事項

4.1 使用前務必詳閱此說明書，并遵照指示步驟，依次操作。

4.2 請勿使用非原廠提供之附件，以免發(fā)生危險。

4.3 進行測試時，本儀器測量端高壓輸出端上有直流高壓輸出，嚴禁人體接觸 ，以免觸電。

4.4 為避免測試棒本身絕緣泄漏造成誤差，接儀器測量端輸入的測試棒應盡可 能懸空，不與外界物體相碰。

4.5 當被測物絕緣電阻值高，且測量出現指針不穩(wěn)現象時，可將儀器測量線屏 蔽端夾子接上。 例如：對電纜測纜芯與纜殼的絕緣時，除將被測物兩 端分 別接于輸入端與高壓 端，再將電纜殼 ，芯之間的內層絕緣物接儀器 “G”，以消 除因 表面漏電而 引起的測量誤差。也可用加屏蔽盒的方法， 即將被測物置于金屬屏蔽盒內，接上測量線。

Safety precautions for the insulation volume surface resistivity tester
4.1 read the instructions before use, and follow the instructions step in operation.
4.2 do not use the accessories provided by the non original factory in order to avoid the danger.
4.3 when the test is carried out, the high voltage output of the high voltage output end of the instrument is on the end of the instrument, and the human contact is strictly forbidden, so as to avoid the electric shock.
4.4 in order to avoid the error caused by the insulation leakage test bar itself, the instrument for measuring input test bar should be suspended, do not collide with the external object.
4.5 when the insulation resistance of the measured object is high and the indicator is unstable, the clamp of the instrument measurement line can be attached. For example, for the insulation of cable core and cable shell, the two ends of the tested object are connected to the input terminal and the high voltage terminal respectively. Then the inner insulation of the cable core and the core is connected to the instrument "G" to eliminate the measurement error caused by the leakage of the surface. It can also be used with a shielding box, which is placed in a metal shield box and attached to the measuring line.
