4.5. Gain Factor (Fct)
The “Fct” value is the conversion value of gain factor. 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. The value is referred to as the “Fsc” number on the sensor.
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 “FSC”
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 Gain Factor 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.
Then gain factor 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 ‘Fct’
value to be programmed. A wrong value of this parameter will give a wrong reading of
CO concentration. If it is modified the gain factor 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.
