Raw signal graph
To view the raw signal graph which shows the raw gas and ABurst signal and to
check that both signals are not above 125,000 counts.
A raw signal above the limit will raise an error status and
incorrect readings.
Excessive gas concentration for the path length used may
result in unacceptably high raw gas signal.
