The non-contact voltage tester testo745.
They are the first of their kind: voltage testers which meet
the latest standard and which can also measure current.
This means the two instruments are suitable for virtually all
daily electrical measuring tasks. Each time they are used
they automatically select the right settings and therefore
prevent dangerous incorrect settings. Both models have
all the important functions for determining voltage/de-
energization, for measuring current and resistance, as well
as for continuity tests. Their measuring tips can be changed
easily, so that the whole instrument does not need to be
replaced in the event of damage.
The non-contact voltage tester with a measuring range of
up to 1,000V is particularly well-suited to fast initial check-
ing of any suspected fault sources. When the presence
of alternating voltage is determined, the testo745 gives a
warning via a clear visual and acoustic signal. In order to in-
crease the reliability, the voltage tester has a filter for high-
frequency interference.
