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

Deprecated
