ensure continued safe operation of the instrument.
Earth Resistance; 25 VDC applied between case and protective earth, bonding resistance should be < 0.1 Ohm.
Insulation Resistance; 500Vdc applied between the earth terminal, and the live and neutral terminal shorted together,
insulation resistance to be >2.0 MOhm. (Mega Ohm, NOT milli Ohm)
Failure to comply with these instructions could result in death or serious injury
