• Keep measuring instruments and accessories out of reach of
children
• In commercial and industrial facilities the regulations for the pre-
vention of accidents as laid down by the professional trade asso-
ciation for electrical equipment and devices need to be observed
• In schools, training facilities, do-it-yourself and hobby workshops
the measuring instruments are to be used under the responsible
supervision of trained personnel.
• The utmost caution is advised when you are dealing with voltages
that exceed 25 VAC or 35 VDC. Even at these voltages you may
get an electric shock that is dangerous to life if you touch the
electrical conductors.
After making sure that the voltage source is idle, connect the
measuring instrument to the terminals of the voltage source that
is to be measured, set the required voltage measuring range at
the measuring instrument and make the voltage source alive.
After completing the measurement, make the voltage source idle
and remove the instrument leads from the terminals of the voltage
source.
• Make sure before each voltage measurement that the measuring
instrument is not in the current measuring range
• Always remove the test probes from the test object before you
are changing the measuring range
• Make sure before each measuring that neither your measuring
instrument nor your instrument leads are damaged
• Make only use of the supplied instrument leads. These are the
only admissible instrument leads
