Install Interconnecting
Cable NOTE
If interconnect cable was not purchased with the Oxymitter 4000, consult the
factory for the proper wire type and gauge.
1. Remove cover (27, Figure 9-4) from junction box (5). Connect the
electronics end of the interconnecting cable (9) to the "FROM PROBE"
side of terminal block (Figure 2-10).
2. Remove cover (27).
3. See (Figure 2-10). Connect the heater power leads, the thermocouple
leads, and the oxygen signal leads of the interconnecting cable to the
terminal block. The cable leads are tagged for polarity. To avoid a shock
hazard, the heater power terminal cover must be installed.
4. Install covers (27, Figure 9-3 and Figure 9-4).

INSTALLATION OXYMITTER 4000
Reference Air Package
After the Oxymitter 4000 is installed, connect the reference air set to the
Oxymitter 4000. Refer to 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 or SPS 4001B.
If using an IMPS 4000, refer to the IMPS 4000 Intelligent Multiprobe Test
Gas Sequencer Instruction Manual for the proper reference air connec-
tions.
If using an SPS 4001B, refer to the SPS 4001B Single Probe Autocalibra-
tion Sequencer Instruction Manual for the proper reference air connec-
tions.
Calibration Gas
Two calibration gas concentrations 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.
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 concentrations of more
than 40 parts per million. Failure to use proper gases will result in erroneous readings.
