Check the insulation resistance and dielectric strength; the measurement of the independent electrical circuits and circuit-to-ground insulation resistance should be greater than between 2Ω, should be less than before the surge in debugging.

Insulation resistance and dielectric strength inspection; surveying the various independent electric wire loop to loop and the insulation resistance should be greater than 2 And less than should be the debug Ω former inter alia tide.

Dielectric resistance and insulation strength inspection; Surveys each independent electrical return route should be bigger than to the place and the return route dielectric resistance 2Ω, when insufficiency should eliminate the tide before the debugging.

Check insulation resistance and insulation strength; measuring the electrical circuit to ground and independent circuit insulation resistance test should be greater than 2 ω, runs out in front of the debug subject to tides.
