Why do you need to RCD a BS3036 socket ring? What are you doing/planning on doing?

Sounds like the heater element is gone, or on it's way.
Have you tried testing after the heater has been on for a while?
You could run a lolipop style circuit, come out of the board in 6mm² to an enclosure containing an RCD, and the run the RFC from the enclosure.

Have you tried testing with the heater disconnected?

i have an doing remedial work on the socket circuit which has been tested by somebody else. One of the observations was no rcd protection so i thought that this needed doing. also i have disconnected the heater and stll a poor reading.
cheers
