Applications
The test instrument consists of a compact housing with a pat-
ented means of retaining the second test probe.
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 test instrument is capable of the following measurements:
–
Insulation resistance with test voltages of 50 to 1000 V
–
Surge protection devices with test voltages of 50 to 1000 V
–
Direct and alternating voltages

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.
