Checking The Ac Voltage; Phase Test; Rotating Field Test (Max. 400 V); One-Hand Test - Testboy Profi III LED+ Manuel D'utilisation

Checking the AC voltage

When placing the probes on an AC voltage within the rated voltage range, both of the lower (12 V +~-) LED's and
the LED's arranged above them illuminate according to the voltage applied. Simultaneous illumination of the lower
LED's indicates AC voltage (~).
If the threshold value of 35 V is exceeded, a signal sounds and lucid vibration can be felt. This indicates a general
hazardous voltage!

Phase test

Contact a conductor with the test probe "L2". If a phase is applied, min. 100 V~, the "<L"-LED illuminates!
For determining the phase conductor, the perceptibility of the indication can be impaired, e.g. by insulating fixtures
to protect against direct contact in adverse positions, for example on wooden ladders or insulating floor coverings,
of a voltage not earthed or also in adverse lighting conditions.

Rotating field test (max. 400 V)

Protective clothing and insulation locations can impair the function.
Hold the complete area of the handles L1 and L2
Place the tip of the probes L1 and L2 on two external conductors (phases) and check to see whether the external
conductor voltage of, e.g. 400 V is applied.
A clockwise sequence (phase L1 before phase L2) is present if the "R" LED illuminates.
An anticlockwise sequence (phase L2 before phase L1) is present if the "L" LED illuminates.
Determination of the phase sequence must always be carried out with the probes transposed. Thereby, the phase
sequence must change.
Note:
The phase sequence test is possible in earthed AC voltage mains supply from 200 V, 50/60 Hz (phase to phase).

One-hand test

Locking both hand parts is possible by the distance piece on the measurement line. The distance of the measure-
ment probes can be adjusted by simply rotating. (Schuko/CEE)

Lighting of the measurement location

Lighting of the measurement locations is switched on and off by activating the L.H button.

Continuity test

(To switch on, place the test probes on one another)
Place the test probes on the line to test, fuse or similar. For a resistance of 0 - 50 k, the green "Rx/" LED illu-
minates and an acoustic signal sounds.

FI/RCD trigger test, PE (protective earth test)

The Testboy Profi III LED+ has a load that makes it possible to trigger a FI/RCD circuit breaker using two buttons
®
(FI\RCD). The FI/RCD (max. 30 mA) is checked between the phase and circuit breaker (max. 240 V).

Replacing the battery

If the batteries are discharged, a warning signal sounds and the device automatically switches off. Immediately re-
place the batteries in order to ensure accuracy of the measurement values.
To replace the batteries, open the battery compartment on the main housing. Use a screwdriver and release the
screws. When inserting the batteries, ensure that the polarity is correct.
Close and attach the battery compartment.
