I try to check the three phase voltage in multimeter, in
125A isolator switch incommer. first i touch R phase, and
then i touch Y phase using multimeter, the moment i touched,
it blasts and that moment i got blindness. multimeter
selector position is correct(750V AC MODE AND RED PROBE WASS
IN v AND BLACK PROBE WASS IN COM. MODE. COULD ANYBODY GIVE
ANSWER FOR THIS TO AVOID FURTHER ACCIDENTS PLEASE?
