High insulation
For very high insulation values, connect the small blue high-voltage lead between the earth pick-up of the black lead and the
G terminal of the instrument in order to avoid leakage current and capacitive current effects or to eliminate the influence of the
surface leakage current.
This reduces the influence of the operator’s hands and gives a more stable measurement.
