Version 0.9.9 (build 1) 21 Jun 2018 

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
