• Green fixed light indicates that instrument is ready and hydrogen signal is below
Reject Level limit.
• Periodically flashing green or red calls for calibration.
• Alternating red and green light while the instrument establishes probe
communication.
• Red fixed light together with Reject on display means the instrument has detected a
leak larger than the set Reject Level limit.
