All RCDS have some variation with trip currents its a normal and accepted thing . Generally speaking electronic ones trip faster than electro mechanical ones as I have found here I have a plug in 30 mA trip feeding the plug board on my bench under fault conditions it trips faster than the 30 mA trip in the house fusebox. Here i use an isolation TX to power whatever im repairing all test gear plugs into raw mains which is the correct way the way TVworkshops do it. The other way of course is to take the earth off your scope(I didn't say that)
