RCBO passes 30mA but fails 150mA but in a strange way. Any ideas?

Are you seeing the same if tested on 'AC' type?

No, it's passing when tested as 'AC'. Set to AC I get: + x1: 29.0ms / - x1: 38.9ms, +x5: 28.3ms / -x5: 18.1ms

Try testing at 250 ma , i had this trouble with a Hagar who told me to test at 250 ,also saying the regs state test at more than 5 X

Theres videos about it. They telling you to use higher trip current...

Ok - just watched GSH's & John Ward's videos on testing type 'A's at 250mA - I'd bet any money this is happening here, however I can't get a reading from my Metrel. I've tried setting it to 500mA at x0.5 but it just fails it without giving an actual time. How annoying. Oh for a Variable setting like on the Meggers. I've just emailed Metrel to see if there is a firmware / software update available.
