Looking for a multifunction tester so I can sign up to a Competent Person scheme under Prat P, the front runners seem to be Fluke 1652 and Megger
1552 at a bit under £500 + VAT, or ... there's this Dilog for under £400 all up, calibrated and everything - and a freebie thrown in!

too good to be true - am I mmissing something? Dilog's wibble says

* Continuity test with auto Null facility to zero out lead resistance
- RCD testing - tripping time, tripping current, ramp current.
- PSCC - prospective short circuit current 0 - 26kA
- Insulation resistance measurement with a test voltage of, 100V, 250V and 500V DC.
- Loop impedance measurement without tripping any type of RCD
- RCD auto test etc
Of course it could be that the Dilog box is a POS ... they don't say ;-)
Any good reason not to buy one?
