  • Page 11: Adjustment And Balancing Of The Sensors

    Adjustment and Balancing of the Sensors General For balancing the sensors of the ESW 308.6 it is no longer required to carry out manual adjustments via a potentiometer as with the forerunning model ESW 307.6. Sensor balancing of the ESW 308.6 is performed from the control field, i.
  • Page 12 When “25” is reached, the sensor is still kept depressed until 4 successive acoustic signals sound. Now the values have been stored and the ESW 308.6 can be operated as usual. Note: If more than 2 sensors have to be reset, automatic calibration has to be performed.

  • Page 13: Calibration Modus On Exchanging The Electronics Unit

    After approx. 2 minutes (the electronics unit twice counts up to 60 seconds in the left segment indicator) 4 successive acoustic signals will sound to signal that calibration is completed. In this status the ESW 308.6 can be operated as usual again. It is recommended, however, to check each sensor again.
