You can disable the channel or use it in the scan. Perform step a or step b:
a. If you do not want to use the channel, press SHIFT and then CH-OFF to dis-
able the channel. Available channels that follow will also disable. Note, how-
ever, that channels for the other slots are not affected.
b. If you want the channel in the scan, you can either use the presently selected
function or select a valid measurement function. When you press a function
key (i.e., DCV), the channel assumes the setup of the selected function. Avail-
able channels that follow will assume the same setup. Note, however, that
channels for the other slots are not affected.
For the Model 7700, DCI and ACI cannot be selected for module channels 1
through 20. DCI and ACI are the only functions that can be set for module chan-
nels 21 and 22.
If you did not disable the channel, make your setup changes (if any) for the
selected function. These changes do not affect the following channels.
Using the or keys or the CLOSE key to select the channel, repeat steps 2-2
and 2-3 to set other channels.
When finished setting up channels, press ENTER to proceed to set up triggering.
If there are not at least two channels in the scan list (two or more channels
enabled), the message "INVALID LIST" message will appear briefly. You will
not be able to exit from the scan configure menu, or finish the scan setup until
you enable at least two channels.
The remaining steps are used to check or change the setups for triggering, timer,
and reading count. If you are not going to make changes to any of those setups,
you can exit from the scan setup menu by pressing EXIT twice. The instrument
returns to the normal measurement mode.
