U SAGE Subsequent to powering the correctly wired device would start to tick and after 10 - 20 s ECHO LED go on and 4 ... 20 mA signal appears on the current output. Measurement will be according to the factory setting. The factory setting is throughout apt to check proper working and to perform simple measurement tasks but features residing in the unit can only be utilised by adjusting the EasyTREK to the application by programming.

  • Page 18 P05: - - - - Minimum measuring distance (Dead zone- Close-end blocking) FACTORY DEFAULT: X as per chart The range, beginning with the sensor’s surface, within which (due to the physical restraint of the ultrasound measurement system) measurement can not be made, is called the dead zone. The EasyTREK will not accept any echo within the blocking distance set here. Close end blocking may be represented as the extension of the dead zone within which a possible echo will not be taken into consideration making possible to exclude disturbing objects near to the sensor.
  • Page 19 P06: - - - - Far end blocking FACTORY DEFAULT: 0 Far end blocking is the range below the level set in parameter P06 . The far-end blocking can be used to avoid disturbing effect of stirrer or heaters at the bottom of the tanks. Detecting echoes in this range the unit provides special signals.
