2.3 Spectrum Reading Cycle

As with the oil detection system the spectrum analyser requires the laser light as an
illumination source therefore the analyser will not operate when the measurement cycle is in
the stopped position.
The spectrum analyser can take a reading based on any one of three conditions:
• The OIW System software periodically requests a reading – based on a user selectable
time period;
• The PPM level rises above the "User Set" trigger level;
• The user manually requests a reading.
Each of these trigger conditions will be discussed in more detail below but the reading cycle
remains the same for each condition.
The user can have any combination of trigger conditions including all conditions at the same
time i.e. the system can be set to trigger a reading every hour and trigger a reading if 100ppm is
exceeded and select a manual reading. Note: only one reading will be taken at a time.
