Version 0.9.9 (build 1)  

New:

  • Introduction of "Rapid / Accurate" measurement principal to allow rapid detection of transient faults without sacrificing accuracy for high resistance, moderately capacitive circuits.
  • Concept of uncertain measurement introduced. If accuracy can not be guaranteed, then the SA380-IT will report "Not-a-Number" (NaN) and set a a data quality error flag for the affected circuit.
  • Enhanced technicians mode display that reports a re-settable "min, max and average" for a circuit under test.
  • Device health, Earth Loop reading, Circuit Voltages. Up-time, temperature and GSM signal strength snap-shot readings reported periodically
  • Device health, earth loop reading and circuit voltages reported upon change (user configurable)
  • Average resistance to earth readings for each circuit over the last reporting period (user configurable) send back at the end of each period.
  • New threshold reporting scheme introduced
    • 3 "set" thresholds configurable for an AC or DC circuit
    • 1 "clear" threshold configurable for an AC or DC circuit
    • Upon 1st breach of threshold in a given reporting period, the following data is captured
      • The average resistance on the affected circuit since the last average was taken, up to the the current time
      • A single snap-shot of resistance to earth on the affected circuit at the moment of threshold breach.
      • A single snap-shot of circuit voltage at the moment of threshold breach.
    • The act of acquiring a snap-shot reading resets the average reporting period.
    • No further snapshot events until:
      • The periodic reporting period ellapses
      • A different "set" threshold is breached
      • the "clear" threshold is reached, this "re-arms" all "set" thresholds and allows them to fire once more.
    • The number a transient events reported over a given averaging period is capped (user configurable). This limits data volumes experienced on circuits that are suffering from frequent and large resistance to earth deviations due to:
      • Highly variable circuit insulation
      • Highly variable measurement earth connection quality
      • Interference from a second IMD leaking through via circuit-to-circuit insulation faults.
  • Interlock events are now available in the syslog
  • Better default date and time selection ranges in syslog search
  • Maximum reportable voltage now 175V AC/DC (The maximum working voltage of the product)
  • Hidden enhancements regarding the frequency and robustness of internal device safety checks
  • New version dUpgrade released to allow automated bulk upgrade of SA380-IT devices
