Sparkingchip:
I have just looked at the Martindale tester data sheet and I am not seeing anything in the specification specifically about measuring voltage drop.
Perhaps I am wrong, but I assumed a voltage drop tester would allow you to test using a dummy load of 6, 10, 16, 20, 32 or 40 amps so that you can instantly test a standard circuit without having to connect loads actually to the circuit by for example turning all the lights on or plugging in electric heaters. . .

I have had a look at the Martindale data sheet on a bigger screen than my phone, it calculates the voltage drop from the measured impedances at the test point and at the reference point upfront of the circuit in the distribution board taking into account the rating of the circuit protective device, rather than applying a load.

Precisely! See my note above. Maybe the hot Easter sun has got to JW - the presentation falls short of his usual standard. Let's stop all this nonsense about measuring voltage and applying loads. You wouldn't pass your C&G if you tried that approach. ?
