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.
"<L" LED lights up. The voltage indicator should give a reading of approx. 400V. If the only reading is 230 V, only
one phase conductor is connected.
8. Continuity / diode testing
Bring the probe tips into contact with the conductor, fuse or resistance that is being tested. From 0 ... 500 kΩ or
with the "+" probe tip at a the anode of a diode, the "Rx/Ω" LED lights up and you will hear an acoustic signal
sounds.
9. Voltage test with RCD trip test
The Tester 2550LED is equipped with a switchable load, which permits the testing of FI/RCD-safety switches. The
FI/RCD safety switch (max. 30 mA) is triggered.( max. 240V)
10. Battery replacement:
To replace the batteries, release the screw under the main casing and pull the battery compartment cover down-
ward 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.
