Pulses on and off to indicate that the system is powered on (power
status).

Average baseline of CO

BSLN
Indicates that the process is in the Baseline phase for the first 10
readings.

for the Graph setting and can be modified under Main > Settings >
Settings 2 > Graph. (For example, when Max CO2 is set to 1000 ppm,
this graph shows 250 ppm.)
Abort Button
Stops the Injection process and returns to Injection – Settings (Step 2).
Process data is not saved to the USB flash drive.
New Button
Stops the Injection process and returns to Injection - Settings (Step 2).
Injection Process results are saved to the USB flash drive.
If the baseline (B) does not drop to either 0 or a very small number (typically 1-3 ppm), then there is either
a leak in the system, or the system has not adequately “zeroed”. Try aborting the process, wait 2-3
minutes, and try again. If the problem persists, check the Injection setup for leaks and ensure that the
absorber column is properly seated and contains fresh soda lime.
Injection Step 6 – Injection Phase
During the Injection Phase, the syringe should be slowly and steadily injected into the airstream through
the septum. The injection rate should not exceed 3 ml/second to avoid over-pressurization of the system
(in other words, it should take the user at least 3 seconds to inject a 10 ml syringe).
