Safety Rules
l Use the Meter only as specified in this
manual, otherwise the protection provided
by the Meter may be impaired.
l Do not operate the Meter before the cabinet
has been closed and screwed safely as
terminal can carry voltage.
l Make sure before each measurement the
Meter is set to the suitable range.
l Before using the Meter, please inspect
the cabinet and test leads for damaged
insulation or exposed metal.
l Connect the red and black test lead to the
correct measuring input jack properly.
l Do not input values over the maximum range
of each measurement to avoid damages of
the Meter.
l Do not turn the rotary function switch during
Voltage and Current measurement, otherwise
the Meter could be destroyed .
l Make sure to use new fuses with proper
rating in stead of bad fuses.
l To avoid electric shock or damages, do not
apply more than 1000V between the"COM"
terminals and " " earth ground.
l Use caution when working with Voltages
above 60V (DC) or 30Vrms (AC). These
Voltages pose shock hazard.
