Dc Voltage Measurements; Ac Voltage Measurements; Frequency Measurements - BEHA UNITEST CHB 7 Mode D'emploi

Only handle test leads and probes on the grips provided. Avoid
touching the probes under any circumstances.

4.3.1 DC voltage measurements

4Turn selector switch (3) to "
4Plug the black test lead into the "COM" socket and the red lead
into the "+" socket.
4Connect the probes to the UUT and read the display.
4The optimum range is set automatically.
To change the range manually press the "
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.
