How to test the insulation resistance of metal braided cables? Zc-90 series of resistance meter high voltage output, low voltage input respectively in which position?
When the zc-90 series insulation resistance instrument is used, the high voltage output end is connected with a metal shielding layer. This method is to reduce the environmental interference, so that the reading is more stable.
Series resistance meterMulti core and measuring method for insulation resistance of cable metal sheath: measuring the input (red) and the measured core wire connected to the other core and the outer contact in the high-pressure connecting together with the instrument, the shield (black) no vacancy.
