Operation
Power the meter
IMPORTANT: Power the meter in a room temperature
environment and in an area free of CO; otherwise the
meter will read incorrectly when subsequently measuring
CO.
Press the
button to power on the meter. The LCD will
switch ON and display the programmed CO alarm limit in
the primary display and the ambient air temperature in
the secondary display (as shown in the LCD description
section above). Replace the batteries if the display does
not switch ON.
The meter performs a 15-second self-test during which
the displayed values will blink. When the self-test is
finished, the meter beeps and enters the normal
operating mode.
Measurements
The CO15 detects the existence of carbon monoxide (CO)
in the environment and displays the reading in parts per
million (PPM) in the primary display.
1.
To take a measurement, trace the CO15 around the
area of the suspected leak.
2.
The meter indicates the presence of carbon
monoxide (CO) in PPM in the primary display. The
secondary display indicates the maximum value
since powered on.
3.
Long press the “backlight” button while in
measurement mode to reset the maximum value.
4.
When high CO levels are detected an audible beeper
sounds at 25 ppm alerting the user to the dangerous
CO levels. The higher the concentration of CO, the
faster the beeper will sound.
5.
To turn the meter off, press the
button. The
meter powers off after 15 minutes of inactivity.
Change Temperature Units
The temperature shows on the display during the self-test
only. Power the meter in a room temperature
environment for the most accurate readings. Long press
the
button during the self-test to change the
temperature units to
o
C or
o
F.
