Switching On The Instrument; Phase Test; Phase Sequence Testing; Rotary Test - TESTBOY TV 411 Bedienungsanleitung

Operation

Switching on the instrument

To switch on the instrument, briefly press the ON button. The standby LED (3) stays lit once the
instrument is switched on.

Phase test

The status LEDs (1) light up when an AC voltage between 70 and 600 V is detected at the
respective connection A, B or C.
In some circumstances these light up when the test terminals are close to live conductors or
electrostatically charged parts.
This is not an instrument defect, but is due to the non-contact measurement procedure.

Phase sequence testing

To test the direction of the rotating field (right or left) in relation to the phase sequence L1, L2
and L3, connect the non-contact terminals in the sequence red, yellow and green (A, B and C) to
the respective external conductors.
The terminals can be connected directly via the insulated single conductors, with no need for any
electrical contact with the connection cable. The arrow " ▼" on the terminal should be located
above the centre of the conductor.
The direction of the rotating field is indicated via the LEDs of the rotation direction indicator (2):
L= left rotating field R= right rotating field

Rotary test

To test the direction of rotation of an invisible engine shaft (e.g. in pumps or flange-mounted
gearboxes), hold the Testboy TV 411 directly on the housing of the electric motor.
®
Ensure that the output shaft is aligned with the symbol stylized to resemble the tester.
While the engine is running, the LEDs of the rotation direction indicator (2) now indicate the
direction of rotation of the engine shaft.

Switching off the instrument

To switch off the instrument, briefly press the OFF button. The standby LED (3) goes out when
the tester is switched off.
