Hi, I carried out a RCD test for the first time yesterday, but I was not happy with the results, as it tripped the main RCD in the wall socket, so left RCD test until I had more info, I reset the Wall RCD and I continued with an IEC lead test which was ok I then tried to do a portable appliance Class II test all ok until the load test where the 350 gave me and Alert box saying "Mains Relay Safety test has failed Code 0400" " Please re-check the incoming mains supply" Press the Green Start key to re-start.
I have checked all fuses 1 in the mains lead (Black round connector lead) and both fuses in the battery compartment and all are OK. but when I re-try the test I get the same Alert. so I cannot do any testing which requires the mains to be present.
Has anyone any ideas.
Regards
Mitch
