13.3.1 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. The [CO
2
Standby]
message appears on the screen when the CO
2
module is plugged. To set the CO
2
module
to measure mode, Select the
hardkey on the module to switch to the [Measure]
mode, or select the CO
2
parameter window→[Operating Mode]→[Measure]. The
message [CO2 Startup] is displayed.
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.
CAUTION
z The watertrap collects water drops condensed in the sampling line and therefore
