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 1
st
Alarm Value, 2
nd
Alarm Value, Full Scale Value, Conversion Value
of the Sensor, and Gain Factor.
b. Adjust Alarm values at this time if needed see “12.9. Pro CO Alarm Settings“.
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 monoxide in a
confined space that does not have good ventilation. Exposure to carbon
monoxide 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 psi) 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.
It is very important that the calibration take place at atmospheric pressure (1 bar) and
roughly 68° F (20° C) with the surrounding air being clean of CO. Calibration performed in
air with CO such as aboard a moving boat with diesel exhaust or construction site with
diesel engines operating will affect the calibration. On a moving boat air flow can trap the
engine exhaust in the cabin or open deck area creating a high CO environment that will
affect calibration.
Low pressure where
CO can be pulled in
from the exhaust of the
boat engine.
