You get any PCAS system to give faulty alerts and advisory’s by simply arranging for iffy power.
Why would you do that?
If you use the small unit and rechargeable you get about 4 hours, and then it will give you lots of spurious results.
Presumably after ignoring the low battery warning.
Hardly a fault it the unit though.
True. Maybe that is SNS3Guppy's problem - low batteries or iffy power - anything is possible I suppose if you try hard enough.
