CARD menu tree
CARD: VIEW
— This menu item is used to view all channels that are presently closed.
The channels are built into a string that scrolls the display. Four dots identify the end of the
string. Model 7751 example (Slot 1) — Assume the following string is scrolling across the
display:
101, 114, 118 . . . .
The above scrolling string identifies the 7751 channels closed to connect channel 1 to the
DMM. The complete simplified schematic of the 7751/7752/7753 is shown in
Figure 2-12 .
SLOTX: 77xx
— Use to scroll the closed channels for the switching module in Slot X
(where X = 1 or 2).
Scrolling speed
— The scrolling speed of the channel string is adjustable or can be
paused. The key slows down scrolling speed and the key speeds it up. The ENTER
key pauses scrolling. Press ENTER a second time to resume scrolling.
Exiting VIEW
— To exit from VIEW, press the EXIT key. Pressing an instrument setting
key will also exit VIEW, but it will also perform the operation associated with the key. For
example, pressing
Ω
2 will exit VIEW and select the
Ω
2 function.
