Repairs, Parts Replacement and Balancing
When the instrument is opened, voltage conducting parts may be
exposed. The instrument must be disconnected from the measuring
circuit before repair, replacement of parts or balancing. If repair or bal-
ancing of a live, open instrument is required, this may only be carried
out by trained personnel who are familiar with the dangers involved.
Defects and Extraordinary Strains
If it may be assumed that the instrument can no longer be operated
safely, it must be removed from service and secured against uninten-
tional use. Safe operation can no longer be relied upon:
•
If the instrument demonstrates visible damage
•
If the instrument no longer functions
•
After long periods of storage under unfavorable conditions, e.g.
humidity, dust, excessive temperature.

Application
The multimeter is an analog multimeter with an electronic amplifier. It
offers a great number of applications in the field of the electrotechnical
practice, e.g. in research and development, manufacture, operation,
test room and service as well as in the field of training and further edu-
cation.

Description
The multimeter features 46 measuring ranges for DC and AC voltages
up to 1000 V, AC voltage levels from –40 to +62 dB, DC and AC cur-
rents up to 10 A and resistances up to 20 M
. It has a constant input
resistance of 10 M
on all voltage measuring ranges.
All measuring ranges are selected with a central range switch. They
are clearly arranged in the turning area of the switch.
Measuring unit and indicating unit are housed in two different case
halves which are connected with each other across a joint with a
stepped stop device. An optimum reading angle can thus be set in all
positions of use for easy reading.
