6.3.5
Insulation resistance (supply circuit to accessible surfaces of
class II equipment)
The insulation resistance test checks the resistance between primary supply circuit and
the isolated accessible conductive parts of the welding machine.
The instrument measures the insulation resistance between:
-
mains test socket‘s live terminals on 3-phase instrument and the S/C1 terminal
on MultiservicerXA.
