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 37: Maintenance And Repair

    EasyTREK SP units do not require maintenance on a regular basis. The need for cleaning of the sensor head may occur. Cleaning should be performed by utmost care where scraping or denting of the transducer have to be avoided. Repair under or after the guarantee period should only be carried out by Nivelco. Devices for repair should only be returned duly cleaned and disinfected.
