To disable monitor, again press SHIFT and then MONITOR (MON annunciator turns off).
Once enabled, you can change the monitor channel using the CLOSE key or the
keys. If you open the monitor channel, the monitor does not disable but it does become
inactive (MON annunciator turns off). When a channel is closed, monitor becomes active
(MON annunciator turns on).
While in the normal measurement state, the present monitor channel dictates which chan-
nel in the scan list is the monitor. Therefore, if you change the monitor channel, the scan
list monitor channel also changes.
When you change the monitor channel while in the normal measurement state, the instru-
ment setup does not change. If you want the monitor channel to assume the setup of the
scan list channel, you must disable the monitor and then re-enable it.

Auto channel configuration

Auto channel configuration allows you to recall scan list setups. With auto channel config-
uration enabled, a closed channel assumes the scan list setup. With this feature, you can
inspect the channel setups of the scan, or manually scan channels. When a scan channel is
disabled (not in scan list), it cannot be closed with auto channel configuration enabled.
As with normal operation, when you use the
channel pair), any other closed channels are first opened.
Perform the following steps to enable or disable auto channel configuration.
