The Device Monitor window can be invoked by the Monitor - Device
Monitor command from the Instrument window or using the Device
Monitor icon. It allows to Autozero the detector, turn its lamp(s) on or off
and start the data monitoring outside of the analysis run. The Device
Monitor window also displays the actual lamp state and the detector cell
temperature.

Check Signal On (Off)
Turns the detector signal monitoring on and off. Active only when analysis
is not running.
Note: This type of detectors is giving data only during analysis. Pressing this
button starts a "dummy" analysis run (all data discarded) that allows to
check the detector signal before the actual analysis. It should be turned
OFF before starting the analysis by external contact.
Caution: The Check Signal On function can not be activated when a Purge was
used to set the flow and composition manually from the Device Monitor.
You need to use the Resume Idle function from the LC Device Monitor
first.
