5.3 Voltage measurements
Do not connect more than 600 V AC / DC to the input
sockets. Exceeding these values can endanger the op-
erator, and may result in damage to the instrument.
Before switching to a new function, disconnect the
probes from the UUT.
Only handle test leads and probes on the grips pro-
vided. Avoid touching the probes under any circum-
stances.
Turn selector switch (2) to 400V
Plug the black test lead into the "COM" socket and the
red lead into the "V
Ω
" socket
Connect the probes to the UUT and read the display
If the display is not visible during measurement, press
the "HOLD" button (3) to retain the display. The probes
can then be removed from the conductor and the
stored value read.
5.4 Resistance measurements
Disconnect the UUT from all sources of supply and
check that it is at zero voltage.
Turn selector switch (2) to "V
Ω
"
Plug the black test lead into the "COM" socket and the
red lead into the "+" socket
Connect the probes to the UUT and read the display
If the display is not visible during measurement, press
the "HOLD" button (3) to retain the display. The probes
can then be removed from the conductor and the
stored value read.
