• You can, in the future, create a calibration for any slot that was not initially calibrated
when Instrument Setup was first enabled.
• To delete the current calibration from a slot, set the appropriate slot to Off. To
recalibrate the slot, reselect it and then click Start.
• To clear the instrument of its current setup, click Reset.
2.1.2 Acquisition Modes
The ACQUITY RDa Detector supports two acquisition modes:
• Full Scan
• Full Scan with Fragmentation
Full Scan
This mode collects Full Scan data at a single fixed cone voltage. This is typically the lowest cone
voltage that produces the optimum precursor ion signal.
Full Scan with Fragmentation
This mode collects mass spectral data for the parent ion and its fragments. Use the fragment ions
to add confidence when identifying an analyte.
Note: Do not open the instrument door during data acquisition. Doing so places the instrument
into Power Save mode.
Tip: Consult the instrument online Help for further details about using the Acquisition modes.
2.1.3 ACQUITY RDa Detector health system
The ACQUITY RDa Detector's health system constantly inspects and monitors performance. If an
issue is detected, the instrument immediately notifies you via the software and front display. The
instrument self-diagnoses problems. Depending on the severity of the issue, the instrument either
requests that you carry out some intervention to correct the issue, or informs you that you must
contact Waters service.
Depending on the type and cause of the failed health check, the instrument moves to either
Check state or Error state. In the Check state, the software displays a health card that explains
how you can rectify the problem. When you complete the instructions outlined, the instrument
runs the test again to confirm that the issue is corrected. If the issue remains, another solution
may be displayed as detailed below.
If multiple health checks are flagged as problems, they are displayed in a prioritized order. Errors
are always presented ahead of Warnings, as Errors require you to contact your Waters service
engineer. Once a health check is rectified, the next in priority is displayed until all are resolved.
