1.2 Introduction:

This instrument is a digital meter that
measures CO concentration and
Temperature. Through the easy to use
control, the meter detects the presence of
Carbon Monoxide (CO) and measures
concentrations between 0-1000 parts per
million (ppm).
The digital meter indicates the presence of
carbon monoxide in two ways:
▪ A reading on the LCD in ppm.
▪ A beeper tone.
Alarm System:
▪ The higher the concentration of CO, the
faster the beeper sounds.
▪ Above 200 ppm, the beeper sounds
continuously, while the frequency of the
tone increases with the concentration of
CO.
▪ Above 1000ppm, the beeper sounds
continuously with the highest frequency
of tone. The LCD reads "OL" to indicate
an out of range condition.
Self-Test:
Install the batteries. To turn the meter on,
