When connected to an AC voltage source
both the + and – LED's will illuminate.
The polarity LED's will illuminate when the
voltage source is ≥ 12V AC rms or DC.
Voltage threshold indicators
The voltage threshold LED's
illuminate when the magnitude of the voltage
source is at a value approaching or greater
than the corresponding marked voltage. For
example if the voltage source is 55V AC rms
then the 24V and 50V LED's will illuminate,
if 690V AC rms all voltage threshold LED's
from 24V to 690V will illuminate.
ELV indicator
If the batteries are low or exhausted a
hazardous live voltage will not be indicated
by the polarity or voltage threshold LED's,
but an indication of a voltage above the ELV
limit (50V) will continue to be indicated by
the ELV LED
Continuity indicator
The continuity RX LED
indicate continuity of a circuit under test.
Phase Indictor
The phase LED
AC voltage when the unit is used as a single
pole phase detector.
Buzzer
The buzzer will sound when:
Voltage above the ELV threshold (50V) is
present,
or AC voltage is detected when used as a
single pole phase tester,
or circuit continuity is detected.
3.2 Low Battery Check
Before and after each use short the test
probes of the voltage tester together and
check for an audible tone.
If there is no audible tone the batteries need
to be replaced (see section 4.1 Battery
Replacement).
Do not use the unit if the batteries need
replacing.
3.3 Operating Duty Ratio
The voltage tester should be operated (ON)
for a maximum period of 30 seconds. This
should be followed by a recovery period
(OFF) of 4 minutes.
