4.6. Calibration Value (CAL)
The “CAL” value corresponds to the CO PPM content of the calibration test gas to be
used for calibration
1.) Press and hold the Prog button to access the program pages, then release the
button.
2.) Press the On/Off button to cycle through the settings until you reach the “CAL” view.
3.) The blinking digit shows the cursor position.
4.) Press the Prog button to increase the value (from 0 to 9)
5.) Press the Adjust button to cycle the cursor through the digits.
To complete your entry and save the Calibration value, press the On/Off button

5.0. Threshold Alarms
Should the Carbon Monoxide reading go over the threshold alarms (AL1 or AL2) the
instrument will go into alarm mode and will activate the relays output (open collector
max 100mA) and the internal buzzer. The display will show the trespassed alarm and
the actual measured value. To stop the audible alarm, press any key. In this event the
Pro Co Analyzer will remain in alarm mode until the analyzed value goes below the
alarm set point.
The relay output typically is used to shut down the compressor. Nuvair can supply the
necessary components to adapt your compressor to the relay or provide them at the
time of install on a new compressor.
6.0. Powering Off
At the home or gas reading screen, hold down the On/Off button for a couple of
seconds. The Analyzer will display “OFF” and then go blank.
