• Before using the device, check the
housing and the measurement
cables for any damage.
• Do not conduct measurements in
a damp environment. Workplace,
hands, shoes and floor must be dry.
• Before opening the housing all
measurement leads are discon-
nected from the device.
2. Description, technical data
Passive analog multimeter with a
rotary switch for selecting the mea-
surement ranges and a scale with
mirrored background for parallax-
free readings. The device is extreme-
ly robust in terms of load capacity
and is equipped with excellent over-
load protection due to its two anti-
parallel diodes as well as moving coil
movement, which is not sensitive to
external electromagnetic fields. The
safety connection sockets offer pro-
tection against accidental touch con-
tact. The robust plastic housing and
the spring-connected bearing jewels
of the movement guarantee protec-
tion against damage caused by me-
chanical stress.
