MEASUREMENT PROCEDURES
For the most accurate measurement, do not place the
monitor close to any source of CO2.
Note…
Measurement response time is 10 seconds for CO2 and
2 seconds for RH. If the operating environment changes,
it takes approximately 30 seconds for the CO2 sensor to
respond and 30 minutes for the RH sensor to stabilize.
1. Connect the AC power adapter to the monitor and
plug it into a power supply.
2. Set the date and time in the monitor. This should be
done whenever it is turned on. See “Monitor Setup:
Date and Time” on p.12 for instructions.
3. The monitor will warm up briefly and the reading will be
displayed. Levels are updated every 6 seconds.
4. To change the temperature scale, press
UNIT
to cycle
the display between °C and °F.
Note…
When CO2 exceeds 1000 ppm, both the alarm (bell) icon
and the red LED will flash a warning. When the CO2 level
falls below this threshold, these visual alarms will stop.
