16.2.1 Using a Sidestream CO
2
Module
1. Attach the watertrap to the module and then connect the CO
2
components as shown
below.
2. By default, the sidestream CO
2
module is in standby mode. Access the [CO
2
Setup]
menu to set [Operating Mode] to [Measure]. The [CO
2
Startup] message appears on
the screen.
3. After start-up is finished, the CO
2
module needs time to warm up to reach the operating
temperature. The message [CO
2
Sensor Warmup] is displayed. If you perform CO
2
measurements during warm-up, the measurement accuracy may be compromised.
4. After warm-up is finished, you can perform CO
2
measurements.
NOTE
z To extend the lifetime of the watertrap and module, disconnect the watertrap and
set the operating mode to standby mode when CO
2
monitoring is not required.
