The principle of this meter is the Faraday cage equipotential shielding method. All
measuring parts are inside the shield of the metal sphere.
3.Instructions For Use
1. It is recommended to adopt good insulation (such as nylon tube, ABS tube, etc.)
of the same height as HZZGF DC high voltage tester to support the high voltage
microammeter.
2.HZZGF DC high voltage tester high voltage output end is connected to the high
voltage microammeter through the high voltage current limiting resistance, and then
through the special plug of the high voltage microammeter, the shielded wire is connected
to the subject.
3. In order to reduce the influence of corona ion current on the sample current when
the high-voltage cable head of the subject is exposed, it is suggested to wrap the
