    4. Monitoring the calibra�on periods The detector con�nuously checks the calibra�on validity of the connected sensor. A�er 12 months since the last calibra�on (Max. calibra�on interval) the LED "ERR" starts flashing and an inscrip�on starts flashing on the LCD display. The connected sensor must be calibrated immediately. The detector will transmit the informa�on about the ending calibra�on via current loop.
