If beeping alerts you that the detector firmware detected a problem, for
example leakage, beeping continues until you turn off the beep. Pressing
this button turns off the beep for the current alarm. As a standard,
beeping starts again after 10 minutes if the problem is still present or if
the firmware detected another problem.
Pushing the Gas button will perform the following actions:
•
Turn the detector gas flow on and off
•
Turn the drain pump on and off
After you pushed the button for turning off, the drain pump will
remain enabled for a short period longer to remove any remaining
mobile phase.
