5.12.11 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 N2 and the calibration gases one at a time without the three-way valve as shown
in Figure 50.
