With 2998 PDA, repeated wavelength verification failures temporarily resolved by establishing flow - WKB120524

SYMPTOMS

• Wavelength verification failure when system starts
• If flow is established first, issue is not observed
• Happens every time detector is started without flow

ENVIRONMENT

• 2998 Photodiode Array Detector

CAUSE

Broken flow cell. The exit window of the flow cell is cracked but not leaking. 

FIX or WORKAROUND

Replace the flow cell.
