Looks like Ive landed myself an electricians portable tester , does a whole load of mains tests on all relevant values of mains wiring systems , performs insulation testing ,conductor and ground resistance measurements ,RCD and safety testing , and loads more
I have been offered the P.A.T testing course at work , costs a few hundred ,but seems like a good qualification to have , only takes a day ,and your basically qualified to test all manner of appliances in situ , having my own machine to begin with is a bonus too .
Generally it involves current and voltage probes across single or multi phase supplies , and it can graph every parameter of the wiring under load in software .The machine only comes with basic probes , but the addition of current clamps and a few basic accessories ,you can test almost any electrical job short of KV overhead wires .
