Analyzer 2810/2815/2820

Instruction 19-9222

2.0 OPERATION

2.1 Important Note

Always ensure that the analyzer’s gas inlet connector (Figure 1, Item C)

and gas exhaust (Figure 1, Item B) are unobstructed and open to the at-

mosphere. Be careful not to breath directly on the analyzer while taking

a measurement; otherwise, inaccurate CO

readings will result.

2.2 Switching the Analyzer ON/OFF

Switch ON the analyzer by pressing the button. Switch the analyzer

OFF by pressing the button down for at least 3 seconds, or until the

display goes blank. When rst switched on, there is a warm-up period be-

fore the CO

level is displayed – approximately 60 seconds for the 2810/

2815 analyzer, and 20 seconds for the 2820. Note that a normal fresh-air

background reading of CO

is approximately 340 ppm.
