
Set the outlet gauge pressure for each gas to a value just below the maximum
value (P

Always set the same outlet gauge pressure for air and nitrous oxide.

Never set the outlet gauge pressure to a value exceeding the maximum
pressure (P

Always turn on the air supply since air pressure is required for the
spectrometer's pneumatic system.
Warning: Acetylene – Explosion Hazard
Acetylene can decompose explosively at pressures higher than 103 kPa/
1.03 bar/15 psig.
 Always make sure that the acetylene outlet gauge pressure is below this
value.
