2 Safety Features and Precautions
The MERISO PRIME+ test instrument, and the
PROFITEST204HP/2.5kV and PROFITEST204HV/5.4kV high
voltage modules have been manufactured and tested in accor-
dance with the following safety regulations:
Standard DIN EN 61557-1:2007
DIN EN 61557-2:1998-05
IEC 61010-1:2004
EN 61010-1:2002
VDE regulation VDE 0413 Part 1:2007
VDE 0413 Part 2:1998-05
VDE 0411 Part 1:2002
If used for its intended purpose, safety of the user, the instrument
and the device under test is assured.
Read the operating instructions completely and carefully before using the
device, and follow all instructions included therein.
The operating instructions should be made available to all users.
Observe the following safety precautions:
• The instrument may only be connected to a 230 V or 120 V
electrical system (depending on the country-specific design)
which is protected with a fuse or circuit breaker with a maxi-
mum nominal current rating of 16 A.
• Be prepared for the occurrence of unexpected voltages at de-
vices under test (for example, capacitors may be dangerously
charged).
• Make sure that connector, measurement and test cables are
not damaged (i.e. broken insulation, kinks, interruptions etc.).
• The instrument may only be used indoors.
• Impulse withstand voltage of up to 2.5 kV may occur in
measurement category II systems with 230/400 V.
• If only the batteries are to be charged (instrument is ready for
operation in SETUP position), please ensure that the test in-
strument cannot be used by unauthorized personnel during
the charging process.
• Measurement may only be performed on voltage-free equip-
ment and devices.
• Measurements may not be performed under moist ambient
conditions, where condensation has occurred, or in explosive
atmospheres.
• Do not disconnect the measurement cables until the device
under test has been fully discharged.
• Observe accident prevention regulation BGV A3, “Electrical
Systems and Equipment”.
• Do not perform measurements alone: always have a second
person help if possible.
• Make sure that measurement cables are connected correctly.
• Do not touch the test probes at any point beyond the finger
guard.
The MERISO PRIME+ may not be used:
• If visible damage is apparent
• With damaged connector, measuring or test cables (test ca-
bles may not, under any circumstances, be mechanically dam-
aged or kinked, because impaired insulation characteristics
may otherwise result)
• If these no longer function flawlessly
• If the signal lamps on the PROFITEST204HP/2.5kV
(feature B1) and PROFITEST204HV/5.4kV (feature B2) high-
voltage modules are defective
In such cases, the devices must be removed from service and
secured against any possible inadvertent use.
Send the instrument to our Repair and Replacement Parts service
department in such cases (see chapter 12 on page 67).
