Endress+Hauser 4–1
4 - OPERATION
The instructions provided in this chapter should be used to start up, configure
and operate the OXY5500. On the face of the analyzer is an LCD with
programming and data readouts. Refer to Figure 1–1 for an external view of
the analyzer with descriptions.
Starting Up the Analyzer
Before powering up the OXY5500, refer to the system drawings in Appendix A
to confirm the proper power connections to the power supply, temperature
sensor and oxygen sensor.
As soon as the OXY5500 is connected to the power supply, the analyzer begins
running a short self-test sequence. Refer to Figure 4–1.
The display switches to the main measurement screen automatically. Refer to
Figure 4–2.
To achieve a highest accuracy, the OXY5500 should be warmed up for
approximately five minutes before taking a measurement.
After the warm-up, complete a field calibration to achieve accurate
measurements. Refer to “Performing a manual calibration (calibration
using sensor values)” on page 4-40.
Warm-up time may be extended up to 15 minutes if the optode
has been exposed to high concentrations of oxygen.
