Exclusion of Liability
When testing systems with RCCBs, the latter may switch off. This
may occur even though the test does not normally provide for it.
Leakage currents may be present which, in combination with the
test current of the test instrument, exceed the shutdown thresh-
old value of the RCCB. PCs which are operated in proximity to
such RCCB systems may switch off as a consequence. This may
result in inadvertent loss of data. Before conducting the test, pre-
cautions should therefore be taken to ensure that all data and
programs are adequately saved and the computer should be
switched off, if necessary. The manufacturer of the test instru-
ment assumes no liability for any direct or indirect damage to
equipment, computers, peripheral equipment or data bases when
performing the tests.
• Use original accessories only.
• Maximum permissible voltage between test probe and ground
is 300 V!
• Maximum permissible (externally applied) voltage between the
test probes is 600 V!
Opening of Equipment / Repair
The equipment may be opened only by authorized service per-
sonnel to ensure the safe and correct operation of the equipment
and to keep the warranty valid.
Even original spare parts may be installed only by authorized ser-
vice personnel.
In case the equipment was opened by unauthorized personnel,
no warranty regarding personal safety, measurement accuracy,
conformity with applicable safety measures or any consequential
damage is granted by the manufacturer.
1.4 Applications
The test instrument is enclosed in a compact housing with a pat-
ented means of retaining the test probes.
The high-contrast, four-color OLED display assures excellent legi-
bility. When performing measurements under unfavorable light
conditions, measuring point illumination can be switched on –
white LED at the front.
The RCD test instrument is capable of the following measure-
ments:
– RCD disconnection time
– RCD breaking current
–Touch voltage
– Loop impedance without tripping the RCD
– Phase detection

2 Device Description
2.1 Housing
Figure 2.1: Top View
For transport purposes, the movable test probe can be attached
to the housing and retained by a magnet such that both metal tips
are simultaneously recessed and protected.
In order to charge batteries which have been inserted into the
instrument, the flexible test probe’s connector plug must be
removed and the slide must be pushed to the left, so that the
socket at the right is made accessible and the charger can be
plugged into it.
