To Calibrate The Gas Sensors - Agilent Technologies 7697A Advanced Operation Manual

To calibrate the gas sensors

Advanced Operation
Select Tray then press [Enter].

The Status line of the calibration display shows the last
manual calibration, or Not calibrated if using the factory
defaults.
Rail axis offset, Gantry axis offset, and Z-axis offset display the
current calibration values.
Scroll to Start calibration, then press [Enter]. The calibration

routine starts.
The vial pressurization gas and carrier gas sensors can be
calibrated. The EPC gas control modules contain flow and/or
pressure sensors that are calibrated at the factory.
Sensitivity (slope of the curve) is quite stable, but zero offset
requires periodic updating.
• When calibrating a pressure sensor, turn off the gas
supply at its source and disconnect from the HS to
release any residual backpressure.
• When calibrating a flow sensor, turn off the gas supply at
the source, but leave it connected.
Press [Options], scroll to Calibration, then press [Enter].

Select Vial sensors or Carrier sensors, then press [Enter].
2
Select the desired sensor (if available), flow or pressure.

• Press [On/Yes] to calibrate the sensor.
•
Press [Off/No] to restore the factory defaults.
The HS will measure the offset and adjust the sensor.
