11.9 Pro CO Alarm Setting (AL 1 & Al 2)
1.) Press the “Prog” button for more than two seconds and then release the button.
On the display will appear “Pr” for two seconds, then “AL1” will appear and be ready
for changing the value of the first alarm point. After a second the display will show the
value of “AL1” CO ppm current setting.
2.) The blinking digit shows the cursor position.
3.) Press the “Prog” button to increase the value (from 0 to 9)
4.) Press the “Adjust” button to move the cursor to the next digit, the “Adjust” button will
be used to cycle through the rest of the digits.
5.) To complete your entry and save the CO ppm value, press the “On/Off” button. You
will then automatically jump to “AL 2” programming view.
6.) Repeat steps 3 through 5 to modify and save the “AL 2” CO ppm desired value.
7.) Once programming of “AL 2” is complete you will be in the “FSC” Value Screen and
ready for programming this value. To jump to the end continue to press the “On/Off”
button until the end screen appears.
11.10 Full Scale Value Setting (FSC)
Once the alarms have been set the Pro CO Analyzer goes to “FSC” view so that you can
change the analog full scale value. It is not necessary to modify this value which is factory
set at 300. However if installing a new sensor the value on the sensor can be entered into
the “Fsc” setting and must be entered into the “Fct” setting. This is the Carbon Monoxide
concentration corresponding to 20 mA on the analog output. 4mA is the value at 0 ppm of
Carbon Monoxide. This value can be changed in the same manner as the Alarm settings:
1.) Press the “Prog” button for more than two seconds and then release the button.
On the display will appear “Pr” for two seconds, then “AL 1” will appear. Press the
On/Off button to cycle through the Alarm settings until you reach the “FSC” view. The
“FSC” screen and a 3 digit value will alternate for a few seconds and the Pro CO
Analyzer will be ready for adjusting the “FSC” Value.
2.) The blinking digit shows the cursor position.
3.) Press the “Prog” button to increase the value (from 0 to 9)
4.)Press the “Adjust” button to move the cursor to the next digit, the “Adjust” button will be
used to cycle through the rest of the digits.
5.)To complete your entry and save the FSC value, press the “On/Off” button. You will
then automatically jump to “nA” programming view. To continue pass this to the end
press the On/Off button until the “End” screen appears.
11.11 Conversion Value of Carbon Monoxide Sensor (nA)
After the “FSC” is set the Pro CO Analyzer goes to “nA”, this 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. The display alternates between “nA” and the value of the full scale. The blinking
digit shows the current cursor position.
1.) Press the “Prog” button for more than two seconds and then release the button.
On the display will appear “Pr” for two seconds, then “AL 1” will appear. Use the
On/Off button to cycle through the various settings until you reach the nA” screen. The
3 digit value will alternate with the “nA” screen for a few seconds and the Pro CO
Analyzer will be ready for adjusting the “nA” Value.
2.) The blinking digit shows the cursor position.
