It adopts whole shield (including test line) in order to get rid of the influence of disorder current on the test result, and adopt over-current protection, with advantages of simple operation, high reliability, strong anti-interference and impact current capacity, convenient for maintenance and visual reading etc.
III. Description of use
1. Put in the meter bottom with rotation directly into DC generator or the output bolt rod of DC voltage at the top of the light test transformer.
2. Aim one end of measurement shielded wire with aviation plug onto the aviation socket at the top of the instrument, at this time the meter head indicates 0000, showing instrument is in measurement state.
3. Connect another end of measurement wire to the test sample (note: do not drag the measurement wire).
4. After all wires are connected well, man leaves the test area, now can do DC leakage current test for the test sample, the indicated value of the instrument head is the measured leakage current value.
5. When the instrument head indicates 1, it indicates that the measured value exceeds the measurement scope.
6. Users if wants to increase the test scope or decrease the measurement scope, our corporation can design and manufacture according to users requirement.
