Do not use 100% nitrogen as a low gas
(zero gas). It is suggested that gas for the
low (zero) be between 0.4% and 2.0% O
2
.
Do not use gases with hydrocarbon con-
centrations of more than 40 parts per
million. Failure to use proper gases will
result in erroneous readings.

2-4. PNEUMATIC INSTALLATION (FOR OXY-
MITTER 4000 WITHOUT SPS 4000).
a. Reference Air Package. After the Oxymitter
4000 is installed, connect the reference air set to
the Oxymitter 4000. The reference air set should
be installed in accordance with Figure 2-11.
Instrument Air (Reference Air): 10 psig
(68.95 kPag) minimum, 225 psig (1551.38 kPag)
maximum at 2 scfh (56.6 L/hr) maximum; less
than 40 parts-per-million total hydrocarbons.
Regulator outlet pressure should be set at 5 psi
(35 kPa). Reference air can be supplied by the
reference air set of the IMPS 4000.
If using an IMPS 4000, refer to the IMPS 4000
Intelligent Multiprobe Test Gas Sequencer
Instruction Bulletin for the proper reference air
connections.
b. Calibration Gas. Two calibration gas concen-
trations are used with the Oxymitter 4000, Low
Gas - 0.4% O
2
and High Gas - 8% O
2
. See Figure
2-12 for the Oxymitter 4000 connections.
