Method 1:

Method 2:
1. If a channel is closed, press OPEN to open it.
2. Press SHIFT and then MONITOR.
3. Use the , ,
Δ , and ∇ keys to display the monitor channel (i.e., MONITOR
101), and press ENTER. The monitor channel closes and the MON annunciator
turns on.
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 and
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 , , or CLOSE keys to close a channel (or
channel pair), any other closed channels are first opened.
Perform the following steps to enable or disable auto channel configuration.
1. Press SHIFT and then SETUP.
2. Use the
Δ or ∇ key to display the auto configuration (CH AUTOCFG) setting; N
(no) or Y (yes).
3. Press the key to place the cursor on the present setting (N or Y), and press the
Δ
or
∇ key to change the setting.
4. Press ENTER to return to the normal measurement state.
