Detector functions
1.
Turning on the detector
When the detector power is switched on, automatic test procedures begin, which can take up to 180 seconds, depending on
the sensor used. During this sequence, the internal electronics are tested and the sensor is stabilized to prevent false alarms
after switching on. At this time, only the time (glow) until the start of the measurement is shown on the display. After forming,
the detector starts measuring values and works according to its settings.
2.
Gas detection
The detector continuously measures the concentration of the detected gas in the atmosphere.
3.
Malfunction
In case of malfunction the LCD screen displays the measured concentration, an error code and a key symbol
. On the PCB,
this condition is indicated by the yellow „ERR“ LED. The meaning of each error code is explained in Attachment 2.
4.
Monitoring the calibration periods
The detector continuously checks the calibration validity of the connected sensor. After 12 months from the last calibration
(max. calibration interval),
flashes on the LCD display. The connected sensor must be calibrated immediately.
5.
Reading the record of measured concentrations and alarms
The detector periodically, after 60 s, stores the current detected concentration into its internal memory. The internal memory
retains data from the last 64260 measurements (cca 44 days). In order to read this information, the program DegaConfig is
required. See the DegaConfig program user manual.
