7.) Rotating field testing:
Identify a phase conducting wire as described in point 6. Now connect two phase conductors to the probe tips and touch the
finger contact. If the phase connected to probe tip L2 follows the phase connected to probe tip L1, the phase sequence is
right-handed. The small display indicates "L1". If this is not the case, there is a left-handed field. The voltage indicator
should give a reading of approx. 400V. If "L1"appears in the small LCD screen and the only reading is 230V, only one
phase conductor is connected.
8.) Continuity testing:
Bring the probe tips into contact with the conductor, fuse, etc. that is being tested. With resistances of 0-2 kΩ  t he resistance
reading appears on the display and an acoustic signal sounds. If the reading is >2kΩ, the excess indicator "1" appears on
the display.
9.) FI/RCD trigger test, PE (zero conductor test):
®
The Testboy
Profi er LCD is equipped with an automatic load, which permits the throughput testing of FI/RCD-safety
switches without triggering. The initial task is to carry out testing between L (phase conductor) and N (zero conductor)
(approx. 5s). With immediate connection, L can be tested against PE (earth/ground). The network voltage is indicated. If
this is not so, the FI/RCD safety switch is triggered (max. 30mA).
10.) 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.
11.) Battery replacement:
To replace the batteries, release the screw under the main casing and pull the battery compartment cover downward to
remove. Observe the correct polarity when inserting the new batteries.
Note: Batteries should not be disposed of as normal household waste. Take them to an approved collection point.
