Safety Notes
• The multimeter is EMC-tested and corresponds to the following EG-standard:
89/336/EWG
• This unit is constructed and checked according to DIN 57 41 Part 1/VDE 0411 Part 1,
Safety Requirement for Electronic Measuring Units and Over-voltage Category II (IEC-
1010-2).
• This multimeter may only be used in fuse lines which are protected to 15A. The voltage
must not exceed 250 VDC/VAC and the maximum load must not exceed 4000 VA.
Installations in the overload range III according to ICE 664 are not permitted. The unit
and the measuring cables are not protected against arcing (IEC 1010-2-031, section
13.101).
• If covers are opened, voltage-carrying components may be accessible. Terminals can
also carry voltage. If it is necessary to open the unit for adjustment, maintenance,
repairing or exchange of parts or modules, the measuring unit has to be removed from
all voltage sources
• Capacitors can still carry voltage, even if the unit has been removed from all voltage
sources.
• Please make sure to use new fuses of the proper rating. Do not use repaired fuses and
do not bridge the fuse holders.
• Use special caution when working with voltages above 25V (AC) and 35 V(DC). Such
voltage may cause a hazardous electrical shock if electrical conductors are physically
touched.
• Make sure before each voltage measurement that the unit is not set to the ampere
range.
• Before changing the measurement range, remove the probe tips from the object to be
measured.
• Before each measurement, check the meter and test leads to make sure they are not
damaged.
• Do not use the meter in areas with adverse environmental conditions or where
flammable gas, steam or dust may exist. For your own safety, avoid getting the meter
and test leads damp or wet.
• To avoid an electrical shock, don’t touch directly or indirectly the test probes and the test
points during measurement.
• To avoid serious electrical shock and/or instrument damage, do not apply more than 500
VDC/VAC rms between any meter input terminal and earth ground.
• Do not use meter near strong magnetic fields (loudspeakers, magnets), electromagnetic
fields (transformers, motors, coils, relays, contactors, electromagnets etc.), electrostatic
fields (charge/discharge), and Transmission antennas or HF-generators.
• Don’t switch on the measuring unit immediately after bringing it in from a cold to warm
room. Condensed water might impair or destroy your unit. Give the unit time to warm up
to room temperature before switching it on.
• Safe meter operation is questionable if the unit shows visible damage, the unit does not
appear to work properly, or long-term storage under unfavorable conditions has taken
place.
• For measurements, use only test-leads which are supplied with the meter or equivalent
types. The supplied test-leads are rated for a maximum of 1200V. The maximum rating
of the multimeter is 1000 VDC max or 750 VAC rms. Use special caution when working
with voltage above 25 V AC and above 35 V DC.
