By selection of three push buttons the
voltmeter can be used to measure
external voltages in the range 0 to
39.99 volts via 2mm front panel
sockets. Suitable plugs type Vero
63-1864C or similar
1MQapproximately
Input sockets to voltmeter are fully
isolated from power supply output
terminals
when
operated
in
external
mode.
The
input
terminals
must
