Megger 1730 non trip loop....

[rich.250]

Has anyone else had the problem of it tripping rcds on non trip loop?? seems only wylex in my case.
I have spoke to megger to be told i was performing the test wrong! Quite rude tbh.
I have since spent a lot of time thinking about it and the external earth fault path it takes...
so i have tried switching the two leads polarity, as it can only go the same way.
and it WORKS
have tried it at a few jobs and even tried results on other rcds in both configurations to prove its accurate
would appreciate your feed back.

Seems to be a fairly common problem with Megger Non Trip loop tests, think if you look ther'es a thread about it somewhere

There is a known issue no-trip testing on the Megger 17xx MFTs (no known issues with 15xx models) with certain RCDs and RCBOs, particularly Wylex NSB and NSBS for NH boards. About 4 months ago Megger said they are working on a firmware update to resolve this issue. Contact Megger Technical Department for further assistance.

turn primary function knob to V turn secondary function knob to spanner symbol then the display will show version number latest shipped is V1.09

[trypod]

V 1.07 is the latest for the 1720
