
when measuring insulation resistance between one of the cable conductors and the cable jacket,
the effect of surface resistances (important in difficult weather conditions) is eliminated by con-
necting a piece of metal foil insulating the tested conductor with G socket of the meter;
The same shall apply when measuring the resistance between two conductors of the cable, at-
taching to G terminal other conductors that do not take part in the measurement.
