- No Internal calibration Beam in either Ion Mode
- ESI signal is present when infusing through capillary
- Approximately 800V is seen in the capillary voltage, read back on the tune page during the calibration routine (after the internal calibration heater temperature has stabilized)
Contact strip inside Source Enclosure is not making contact with Internal cal pin
FIX or WORKAROUND
Replace ESI Source Enclosure (700009612)
You can often fix this by pulling down (un-bending) the contact strip inside source enclosure. See KB article 5222 - No Internal Calibration Beam on QDa for more details. Ensure the QDa has been placed in standby before attempting any rework action.
