4.4. Conversion Value of Carbon Monoxide Sensor (nA)
The “nA” value is the conversion value of the Carbon Monoxide sensor in nano Ampere. It
is not necessary to modify this value except when a new sensor is installed. The new
sensor is provided with the new value to be set on this screen.
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 “nA” 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.
6.) To complete your entry and save the nA value, press the On/Off button repeatedly
until the next desired program page is displayed or the end screen appears.
7.) This procedure is used ONLY when a new sensor has been ordered from
Nuvair and is ready to be installed.
The conversion value of the Carbon Monoxide sensor is set in factory and must be
changed only when the CO sensor is replaced. The new sensor will come from the
factory with a label showing the new “nA” value to be programmed. A wrong value of
this parameter will give a wrong reading of CO concentration. If it is modified the
conversion value of the Carbon Monoxide sensor, the instrument will be no more
accurate. All the analysis concentration shown on the display will be wrong. Do not
modify this value. It is necessary to modify this value only at the installation of a new
sensor. Wrong Carbon Monoxide analysis may lead to death.
