Endress+Hauser OXY5500 - Calibration Gas Connections to the OXY5500 Analyzer; Connecting the Gas Inlet for Analyzers Without the Sample Conditioning System (SCS)

Calibration gas connections to the OXY5500 analyzer
Connecting the two calibration gas cylinders to a three-way valve will minimize
the OXY5500 exposure to ambient oxygen. This process will help reduce the
calibration time of the analyzer. The instruction below are for analyzers with
and without integrated sample conditioning systems. If your analyzer sample
conditioning system (SCS) was produced outside the Endress+Hauser factory,
contact the manufacturer for details relating to the SCS connections.
This arrangement is strongly recommended for low-range calibrations (0 to 100
ppmv and lower). Higher ranges may be calibrated by connecting the N
2
and
the calibration gases one at a time without the three-way valve as shown in
Figure 4–38.
Connecting the gas inlet for analyzers without the sample
conditioning system (SCS)
1. Connect the three-way valve to a port connector.
2. Connect the reducers to either side of the three-way valve.
3. Connect to the gas cylinder to the reducer on either side of the
three-way valve using 3 mm (1/8 in.) stainless steel tubing.
4. Connect the OXY5500 probe to the port connector.
Refer to Figure 4–39 for connection locations.
