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.

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 4.9.

To view the sensor output, press the System button to start the

System function.

Use the < > arrow keys to blink More, then press Enter.

Use the < > arrow keys again to move the blinking to the Cell-Output

function. Press Enter. The sensor output will then be displayed on the

screen.

The analyzer is calibrated using 95% oxygen and 100% oxygen as

zero and span gas respectively.

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.
