The 1008a is equipped with an audible and visual alarm for carbon dioxide. The
alarm level is factory set to off. When CO2 above the alarm level is measured, the
1008a will beep and the display will flash red.
The alarm level is adjustable and can be set from 1100ppm to 5000ppm in
100ppm increments.
Using the Arrow keys set the alarm point to the desired level. The
keys adjust the alarm level from “Off” to 5000ppm in 100ppm increments.
Once the desired alarm point is set, press and hold the
key to return to
normal operation.
1) With the 1008a turned on, press and hold down the
CO2 alarm level in ppm

key until the CO2
alarm screen is displayed.
4.7 Ambient Air CO2 Reset
The CO2 sensor can be reset at ambient level as needed. This can be performed if
the CO2 reading seems to be too high or low or just to ensure your 1008A is
operating properly. Note: This does not take the place of a full factory calibration
which is recommended once per year.
1. Take the 1008A outside in ambient air. Allow the CO2 reading to stabilize. Make
sure you are not breathing into the sensor area.
2. Press and hold the
key until the 1008A beeps and the display resets to
400ppm CO2 (+/- 75ppm).
IMPORTANT: DO NOT PERFORM THIS PROCEDURE
INDOORS. IF THIS HAPPENS BY ACCIDENT, PERFORM THE PROCEDURE AS
INSTRUCTED ABOVE TO RESET THE CO2 READING.
