Ammeter LO to V-Source LO connection
The METER CONNECT option of the CONFIG V-SOURCE
menu (see Table 2-15) is used to make or break the internal
connection between V-Source LO and ammeter LO and is
summarized as follows:
1. From the CONFIG V-SOURCE menu, select METER
CONNECT to display the connection options (on or off).
2. To connect meter LO to V-Source LO, place the cursor on
the ON option and press ENTER. Conversely, to discon-
nect meter LO from V-Source LO, place the cursor on
OFF and press ENTER.
3. Use the EXIT key to back out of the menu structure.

Note: Ammeter LO internally connected to V-Source LO

When the voltage source is connected to a
capacitor, the inherent noise of the preamplifier
is amplified. This is expected performance. Adding
a series resistance will not decrease the noise.
However shunting the output of the V SOURCE
(HI to LO) with a 0.1
µ
F capacitor will recude this
noise.

2.9.2 Setting voltage source value
The following information covers the V-Source display, and
explains how to select range and set the voltage value.
Displaying voltage source value
With the instrument in the normal measurement display
state, the programmed voltage source value is displayed on
the right hand side of the secondary display. If in another dis-
play state, you can display the voltage source as follows:
• If a multiple (NEXT) display is currently being dis-
played, press and hold in the NEXT key (or PREV key)
until the NEXT display state is cancelled.
• If in a menu structure, use the EXIT key to back out of it.
