Softus that's the one I bought a year ago, off ebay for £600 (new with callibration certificate). Is now away being callibrated for £50 but they've had it for two weeks already (they also have my gas analyser) and not heard hide nore hare out of them (despite frequent emails to them, accept that they have acknowledged receipt, full feedback regarding the service or lack of on the plumbing forum when th eissue is comcluded). Whereas an offshoot of Megger themselves do a fast turnaround via CEF for £140. I tried the cheap option and it has been proved wanting so far, who knows they may yet break my equipment. Even Ferraris break down.
The mft's work fine except on the low ohms test where a single lo ohms tester (continuity tester) is more sensetive. This is not an issue in the field, it's just that in assessment centres where you can reach each end of the cable without even stretching all the continuity tests yield 0 ohms, so little r1 and little r2 are useless information. Yet the guys using specific continuity testers seem to get a variation. On the job this difference is meaningless. The test centres are badly set up, they should at least use two floors to try and recreate some sense of realism and put some fualts on that are less obvious too. They are so easy to find you could be forgiven for thinking the job is a doddle. Something equating to manufacturers training on boilers where you fly through all the faults they put on, but when you go back into the real world you are scratching your head.
On the plus side most modern mft's don't trip rcd's during the ze test.
For our use an mft is perfectly adequate.
