User Manual

4 GMC-I Messtechnik GmbH
• Measurements under moist ambient conditions are not
permitted.
• Be absolutely certain that the measuring ranges are not
overloaded beyond their allowable capacities. Limit values
can be found in the “Measuring Ranges” table in chapter
12 “Characteristic Values”.
• All current measuring ranges are protected with fuses.
Maximum allowable voltage for the measuring current
circuit is 600 V in all “mA” and “A” ranges.
• We recommend using our KS30 measuring adapter,
available as an accessory, for hazard-free voltage
measurement in power installations with up to 1000 V. The
included internal resistor limits measuring current in the
event of excessive voltage and operator error, and
assures reliable quenching of active spark gaps. For
additional information refer to chapter 7.2 “Voltage
Measurements at Above 600 V”.
Warning!
The instrument may not be operated in explosive
atmospheres, or connected to intrinsically safe
electrical circuits.

DKD Calibration Upon Request
Repair, 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 the performance of repairs, the
replacement of parts or balancing. If balancing, maintenance
or repair 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 unintentional use.
Safe operation can no longer be relied upon:
• If the device demonstrates visible damage
• If the instrument no longer functions
• After lengthy periods of storage under unfavorable
conditions (e.g. humidity, dust, temperature), see
ambient conditions on page 15
