and Opto interrupter
Check Optical Bench heater and
thermistor
Check for pressure transducer problems
as described in Section 10.6.5 and
Section 10.6.1
Check for pneumatic system problems as
described in Section 10.6.1. Check for
flow transducer problems as described in
Section 10.6.5
See Section 10.6.2
