A signal tone is emitted when exceeding the threshold value of 35 V. This tone
signals that a dangerous, life-threatening voltage is present!
Phase testing
Bring one of the probe tips into contact with a conductor, while touching the finger
contact located at the back. When a phase of min. 100V~ is connected, the "<L"
LED lights on.
When using finger contact to determine the phase wire, the perceptibility of the
display can be effected by several factors, including insulated mechanisms that
protect against direct touch, poor positioning (for example, on wooden ladders or on
insulated floor surfaces), an unearthed voltage, or unfavourable lighting conditions.
Rotating field testing (max. 400 V)
Determine which wires are the phase conductors, as described in the "Phase testing"
section. Then place two phase conductors on the test leads and touch the finger
contact. "<L" appears to indicate a counter-clockwise field or "R>" for a clockwise
field. The voltage indicator should give a reading of approx. 400 V. If "<L" appears
only approx. 230 V is displayed, then only one phase conductor is active
Continuity test and diode test
(Hold the test leads together in order to switch on.)
Bring the probe tips into contact with the conductor, fuse, etc. being tested. With
resistances of 0-500 k or a semiconductor diode in the conducting direction (the+
probe tip is applied to the anode!) the "Rx/" LED lights up and an acoustic signal
sounds.
FI/RCD trigger test, PE (PE conductor test)
The ELORA-Testboy
FI/RCD circuit breaker by means of two buttons (FI\RCD). The FI/RCD (max. 30 mA)
is tested between the phase and the PE conductor (max. 240 V).
Battery replacement
To replace the batteries, release battery compartment cover by turning it 90° and pull
downward to remove. Observe the correct polarity when inserting the new batteries.
The positive terminals of the batteries have to show to the centre of the device. The
instrument may not be operated without the cover over the battery compartment.
