– Excited state: Sensor spot becomes excited.
– Emission of light: If the sensor encounters oxygen molecules, the
excess energy is transferred to the molecule, decreasing or
“quenching” the fluorescence signal. The degree of quenching
correlates to the oxygen partial pressure.
Safety Guidelines
All functions of this device has been carefully tested and comply with safety
requirements, prior to leaving the factory. The correct functional and
operational safety of this instrument can only be ensured if the user observes
the necessary safety precautions and specific guidelines presented in this
manual. Refer to Appendix A, Specifications, and the list outlined below.
•
Before connecting the device to the electrical supply network, ensure
that the operating voltage stated on the power supply corresponds to
the main voltage input as described in Table A–1.
•
If the instrument is moved from cold to warm surroundings,
condensation may form and interfere with the functioning of the
system. In this event, wait until the instrument temperature reaches
room temperature before putting the analyzer back into operation.
Please read these instructions and the OXY5500 Safety Manual
(P/N XA02754C) carefully before working with this instrument.
