Rotating Field Testing (Max. 400 V); Continuity Testing; Fi/Rcd Trigger Test, Pe (Pe Conductor Test); Backlighting - TESTBOY Profi LCD Plus Bedienungsanleitung

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 on the display 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 on the LCD and only
approx. 230 V is displayed, then only one phase conductor is active!

Continuity testing

Bring the probe tips into contact with the conductor, fuse, etc. that is being
tested. With resistances of 0-2 kΩ the resistance reading appears on the
display and an acoustic signal sounds. If the reading is >2 kΩ, the excess
indicator "OL" appears on the display.

FI/RCD trigger test, PE (PE conductor test)

The 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).

Backlighting

For operation in low-light conditions, the BL (backlight) sensor activates
automatically to ensure that the screen can be read even in total darkness.

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 de-
vice. Do not use without battery cap!
Batteries should not be disposed of as normal household waste.
Take them to an approved collection point!
