Troubleshooting and Test Functions
Leak Sensor Open
Leak Sensor Open
The leak sensor in the autosampler has failed (open circuit).
The current through the leak sensor is dependent on temperature. A leak is
detected when solvent cools the leak sensor, causing the leak-sensor current
to change within defined limits. If the current falls outside the lower limit, the
error message is generated.
Probable Causes • Leak sensor not connected to the ASM board.
• Defective leak sensor.
Suggested Actions ❏ Ensure the leak sensor is connected correctly.
❏ Exchange the leak sensor.
