changing the current measuring ranges. When making current and
voltage measurements, take care that the range switch is
first set to the
highest measuring range
. Then work down to lower measuring ranges
until optimum display is obtained.
Attention!
!
When the measuring voltage, e.g. 250 V , is applied, do not
switch to the resistance measuring ranges. From the range
x 100 on there is danger of damaging the contacts of the
range switch.
Eye for fastening of the carrying strap
The carrying strap can be fastened at the eyes. It allows for the instru-
ment to be carried around the neck. Both hands are free for measur-
ing.

for setting of the mechanical zero.
Analog indication
Indication of the measured value is effected by a moving-coil core
magnet movement withspring-loaded jewel bearings on a mirror-
backed scale of a maximum length of 101 mm.
Connection sockets
The instrument has four connection sockets which are protected
against accidental contact. They have the following functions:
Socket „10 A“
connector for the highest current meas. range 10 A .
Socket „A|
“
connector for current measuring range up to max.
1 A and for all resistance measuring ranges.
Socket „V“
connector for all voltage meas. ranges (high potential).
Socket „
“
common connector for all measuring ranges to
which earth potential of the measured variable has
to be applied. This input is connected with the
shielding within the instrument.
