GMC-I Messtechnik GmbH 3
• 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!
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.

2 START key:
– Switch on:
Press and hold until the display
lights up.
– Start measurement:
Press and hold until measurement

tion:
Press briefly to switch illumination
on and off.
– Switch off:
Press twice briefly to switch the
instrument off.
