  • long-term high stability of the measurements
  • methods for configuring parameters:
    • via USB and computer program (Windows 7/8/10)
    • from a configuration file stored on an SD
  • checksum allowing detection of unauthorized modification of archived data
  • possibility to differentiate many recorders by assigning individual identification numbers (ID);
  • programmable input type, display range, recording interval, recording start/stop and other configuration parameters such as: calibration of zero and sensitivity, options of SD, LCD display options, alarms, identification number (ID)
  • option of preventing unauthorized changes in parameters of the recorder from SD and transferring archived data from the internal memory to SD (required authorization of the card or free access)
  • option of updating firmware of the recorder
