Diagnostics
The CIRAS-2 contains numerous sensors to measure CO
2
, H

O, leaf environment, signals from external
probes and gas flow through the instrument. The Diagnostics function collects the signals from each of
these sensors and summarizes them. The result is a simple text file that can be faxed or e-mailed to PP
Systems. This can then be compared with our factory records to identify any changes in the system.
There are 6 different dialogs associated with Diagnostics:
Analyser A/D Reads - CIRAS-2 Temperature and Atmospheric Readings, CO
