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.
