C.9.7 Leak Sensor Calibration and Status Screen
Use this screen to display the status of the leak sensors and to calibrate
them.
Figure C-36. Leak Sensor Calibration and Status Screen
Screen Field Description
MEASURED
VALUE
Reports the current measured voltages for the two leak sensors.
TRAY is the sensor installed in the autosampler drip tray. The
OVEN fields are for support of the thermal compartment option.
Note: The thermal compartment option is not currently
available.
CURRENT
CONDITION
Reports the current state of the sensors: DRY if the sensor
reading is within the dry range,
WET if the sensor reading is
within the wet range, or
ERR if the sensor is out of range.
If the measured value drops 0.02 volts below the calibration
value, the current condition is wet. If the measured value goes
0.06 volts above the calibration value, the sensor needs to be
recalibrated.
To calibrate a sensor, press
Select Δ or Select ∇ to select CAL
and then press Enter. The current measured value becomes the
new calibration value. See Section 5.11
for detailed instructions.
CALIBRATION
VALUE
Reports the voltage values set for the calibration.
LOW LEAK
THRESHOLD
Reports the minimum voltage reading that is interpreted as a dry
sensor. A reading below this voltage indicates a wet sensor.
