Resolving detector leak sensor errors
After approximately 1.5 mL of liquid accumulates in the leak sensor reservoir,
an alarm sounds, indicating that the leak sensor detected a leak.
Required materials
• Clean, chemical-resistant, powder-free gloves
• Cotton swabs
• Nonabrasive, lint-free wipes
To resolve a detector leak sensor error:
1. View the Leak Sensors dialog box in the console to verify that the leak
sensor detected a leak.
Tip:
If a leak is detected, a “Leak Detected” error message appears.
2. Open the detector door, gently pulling its right-hand edge toward you.
3. Locate the source of the leak, and make the repairs necessary to stop the
leak.
Warning:
To avoid personal contamination with biologically
hazardous or toxic materials, wear clean, chemical-resistant,
powder-free gloves when handling the leak sensor and its
reservoir.
Caution:
To avoid scratching or damaging the leak sensor,
• do not allow buffered solvents to accumulate and dry on it.
• do not submerge it in a cleaning bath.
