Independent source
When used as an independent source, voltage is available at the V-SOURCE HI and LO terminals on
the rear panel (see the figure below). In this configuration, the V-source functions as a stand-alone
voltage source. The V-source is isolated (>1 G
) from the measurement circuits of the Model 6517B
when V-source LO is not internally connected to ammeter LO (refer to
Ammeter LO to V-source LO
connection
(on page 5-4) for more information).

FVMI source
When used to force voltage measure current (FVMI), V-source LO is connected to ammeter LO as
shown in the figure below. Notice that the V-SOURCE HI and INPUT HI terminals are used for this
configuration. The V-source LO to ammeter LO connection can be controlled from the
METER
CONNECT
option of the
CONF
igure
V-SOURCE
menu (refer to
Ammeter LO to V-source LO
connection
(on page 5-4) for more information).
