Operation
DC voltage testing:
When the probe tips are connected to a DC voltage that lies within the rated voltage range, one of
the lower (6 V + -) or bottom LED indicators lights up to indicate the corresponding voltage. The
upper LED indicators show the voltage, whereby the reference pole is connected to the large
hand element.
AC voltage testing:
When the probe tips are connected to an AC voltage that lies within the rated voltage range, both
of the upper (6 V + -) and the lower LED indicators light up to indicate the corresponding voltage.
Simultaneous lighting up of the upper LEDs indicates the presence of an AC voltage.
Phase search:
Hold one test tip against the earth (ground) lead and use the other tip to check the remaining
leads. The Testboy 40 Plus indicates the AC voltage for the phase in question. FI/RCD is not trig-
gered.
