Measurement
• It is recommend to make measurements
on the secondary side of distribution
panels. Measuring the primary side,
where the current capacity is much
larger, could cause damage to the
instrument or panel in the event of a
short-circuit.
• Do not short the two measurement lines
with the metal portion of the tips of the
test leads. Doing so may cause arcing
or otherwise result in a serious
accident.
• To avoid short circuit or electric shock,
do not touch the metal parts of the
connecting cable clips.
• To prevent electric shock, when mea-
suring the voltage of a power line use
only the specified test lead.
• The optional test leads provided with
this instrument conform to the safety
standard EN61010. Use a test lead in
accordance with its defined measure-
ment category and rated voltage.
• To prevent an electric shock, do not
exceed the lower of the ratings shown
on the instrument and test leads.
To avoid damage to the instrument, do not
apply voltage or current to temperature
probe.
