241-010-005 Mains Tester 3.5×52 Single
Instructions For Use
The voltage indicator is suitable for testing AC Voltages from 100v – 250v against earth.
The metal part on top of the indicator must be touched to operate it and the earthing position of the user largely determines whether it lights up or not.
Failure to light up therefore does not indicate with certainty that no voltage is present.
Damaged mainstesters must not be used.
