Carbon Monoxide Analyzer Manual
4.0 Operation
Prior to each Analyzer use:
1) Turn unit on (hold on/off for 3 sec) and monitor Display for low battery warning. Replace
battery immediately if warning appears. The display will count down from 29 PPM to Att
and then display the current CO
2
level sensed by the analyzer sensor.
2) Cycle through the current settings of the analyzer.
a.
Hold down the “Prog” button for 2 seconds then use the “On/Off” button to cycle
through the low Alarm Value, high Alarm Value, Full Scale Value and end.
b.
Adjust Alarm values at this time if needed see
“4.2”
3) Check Calibration of Analyzer using “Calibrated Test Gas”
Tip: You can check the battery life and current temperature by holding Adjust button for 3
seconds. The display will alternate from battery life to current temperature (Celsius) twice before
returning the home screen.
Do not test cylinders suspected of containing carbon dioxide in a confined
space that does not have good ventilation. Exposure to carbon dioxide can
lead to unconsciousness and death.
Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any
gas stream to be directed at any part of your body.
Never expose the sensor to pressures above atmospheric pressure (0 P.S.I.) or you may
cause damage to the sensor and/or receive false readings. Damaged Sensors will not
provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal
injury or death.
