7-20 Scanning Model 2750 Multimeter/Switch System User’s Manual
NOTES Auto channel configuration cannot be enabled if there is a non-scan channel
presently closed. For example, assume the scan list consists of channels 105
through 110, and channel 101 (a non-scan channel) is presently closed. When
you attempt to enable auto channel configuration from the front panel, the mes-
sage “NOT IN SCAN” is briefly displayed. For remote operation, error -221
(settings conflict) occurs.
With auto channel configuration enabled, the and keys will not properly
step through a non-sequential scan list. Therefore, auto channel configuration
should not be used for a non-sequential scan list. For information on non-
sequential scans, see “(see Scanning fundamentals) – Sequential and non-
sequential scans,” page 7-3.
For remote operation, the ROUT:CLOS:ACON command is used to enable or
disable auto channel configuration (Table 7-1).
Saving setup
Up to three instrument setups can be saved in memory using the SHIFT > SAVE menu
(SAV0, SAV1, and SAV2). A user-saved setup can also be used as the power-on setup. A
user-saved setup can be restored from the SHIFT > SETUP menu. Details on user-setups
are covered in Section 1.
Auto scan
When auto scan is enabled, the scan operation is saved in memory. If power to the
Model 2750 is interrupted, the scan will resume when power is restored. With auto scan
enabled, the last scan setup becomes the power-on setup. It takes precedence over the fac-
tory, *RST or user-saved power-on setup.
Perform the following steps to set auto scan.
1. While in the normal measurement state, press SHIFT and then SETUP.
2. Use the
Δ and ∇ keys to display the auto scan (AUTOSCAN) setting; N (no) or Y
(yes).
3. To change the setting, press to place the cursor on the setting (N or Y) and press
Δ or ∇ to change the setting.
4. Press ENTER to exit from the menu structure.
NOTE With auto scan enabled, DO NOT save the present setup as the power-on default
setup. If you do so, an interrupted scan will not resume.
If during the power-up sequence the Model 2750 detects a card ID change for
any slot, auto scan configuration will disable and an interrupted scan will not be
