Can I downgrade ACQUITY PDA firmware from version 1.69 or later? - WKB46769

Article number: 46769

ENVIRONMENT

  • ACQUITY UPLC PDA Detector

ANSWER

If the detector has a serial number starting with A18 or higher, do NOT downgrade the firmware. These detectors contain a new PDA device that requires its native firmware. If the firmware is downgraded, there will be no signal whatsoever, resulting in a filter wheel "failure to home" error.
