7-16 Scanning Model 2700 Multimeter/Switch System User’s Manual
Advanced scan setup procedure
Step 1: Select the advanced scan configuration menu
1. Press SHIFT and then CONFIG to access the scan setup menu.
2. Press the
Δ
or
∇
key to display INT: ADVANCED and press ENTER.
Step 2: Edit scan channels
1. Use the or key to select channel 101:
SETUP V:101 (factory default)
NOTE The CLOSE key can instead be used to select a scan channel to be edited. Press
CLOSE, use the
Δ
or
∇
keys to display the channel, and then press ENTER.
2. 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
disable the channel. Available channels that follow will also disable. Note,
however, that channels for slot 2 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.
Available channels that follow will assume the same setup. Note, however, that
channels for slot 2 are not affected.
NOTE For the Model 7700, DCI and ACI cannot be selected for channels 101 through
120, and channels 201 through 220. DCI and ACI are the only functions that can
be set for channels 121, 122, 221, and 222.
3. 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.
4. Using the or keys or the CLOSE key to select the channel, repeat steps 2-2
and 2-3 to set other channels.
5. When finished setting up channels, press ENTER to proceed to set up triggering.
NOTE 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.
NOTE 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.
