5.1 Starting up the analyzer
Before powering up the OXY5500, refer to the system drawings in Appendix A → to confirm the proper power

The display switches to the main measurement screen automatically. Refer to Figure 12.
To achieve a highest accuracy, the OXY5500 should be warmed up for approximately five minutes before taking a
measurement.
Warm-up time may be extended up to 15 minutes if the optode has been exposed to high concentrations of
oxygen.
After the warm-up, complete a field calibration to achieve accurate measurements. Refer to Performing a manual
calibration (calibration using sensor values) → .
