4.3.6 Version Screen
Move the < > arrow key to More and press Enter. With Version
blinking, press Enter. The screen displays the manufacturer, model, and
software version information.
4.3.7 Display Sensor Output
The raw output of the sensor can be displayed from the Sensor Output
screen. This is useful during initial sensor calibration where the sensor
output is adjusted to correspond to zero and span values at ambient (or
operating) vent pressure. See Section 6.
To view the sensor output, press the System button to start the
System function.

The Output of the sensor in volts is the first number shown on the
second line. The second number is a raw output of the pressure sensor in
A to D counts.
4.4 The Zero and Span Functions
The analyzer can be calibrated using a background gas without
Oxygen as zero and Oxygen for span gas.
NOTE: After installation, an initial sensor calibration may be required
before the instrument is calibrated in order for the pressure
compensation circuitry to work properly. See Section 6.6.
Connect the calibration gases to the analyzer according to the
instructions given in Section 3.4.1, Gas Connections, and in Part II of this
manual observing all the prescribed precautions.
Shut off the gas pressure before connecting it to the analyzer, and
be sure to limit the pressure to 15 psig or less when turning it back on.
Readjust the gas pressure into the analyzer until the flowrate (as read
on the Analysis Unit flowmeter) settles between 300-1000 SCCM,
preferably 500 SCCM.
