In the auto-test mode the instrument automatically runs through all the six standard tests whilst the operator only has to stand by the RCD and reset it every time it trips. All the result can be viewed using the recall button.
The ramp test slowly increases the tripping current until the RCD trips. The display is in mA. It will show up RCDs that are out of specification and those that will be susceptible to nuisance tripping. It can also be used to indicate which circuits have high leakage currents.
The Kewtech KTD50 also measures main voltage and incorporates a full socket trester that checks for any mis-wiring at the socket.
