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
Deprecated
- per channel acquire on change settings for Voltage
- Acquire-on-Change for resistance to earth
- Delayed Acquisition timed reported
Version 0.9.8 (build 1) 12/02/2018
