Only handle test leads and probes on the grips provided. Avoid
touching the probes under any circumstances.
4.3.1 DC voltage measurements
4
Turn selector switch (3) to “ “.
4
Plug the black test lead into the “COM“ socket and the red lead
into the “+“ socket.
4
Connect the probes to the UUT and read the display.
4
The optimum range is set automatically.
To change the range manually press the “ “ button one or
more times, until the desired range is displayed.
If the display is not visible during measurement, press the
“ “ button (2) to retain the display. The probes can then
be removed from the conductor and the stored value read.

4.4 Frequency measurements
Never measure currents in uninsulated conductors carrying
more than 250 V !
Do not connect more than 600 V AC or 600 V DC to the input
sockets. Exceeding these values can endanger the operator,
and may result in damage to the instrument.
