18th Edition amendment one. Volt drop measurement, who is spreading the rumour we need new testers?

Sparkingchip
Who is the test equipment manufacturer and/ or importer spreading the rumour that we will need new volt drop testers?


Out of interest I have tried an internet search for volt drop testers than can be used to test UK fixed installations and drew a blank with only testers suitable for use in the USA at lower voltages coming up in the search results along with results for auto electrics.

    The Martindale does not appear to be applying a dummy load, just doing a back of a f** packet calculation for you.


    If you were verifying a new socket radial circuit you would need to take some electric heaters or other such appliances with you to verify the installation in am unoccupied property or the like. 


    My Megger loop tester will will calculate r1+r2 after you have taken a reference reading at the distribution board or consumer unit, the Martindale appears to do the same for voltage drop without applying a dummy load.


    That seems a bit pointless without the ability to apply a dummy load except for dedicated appliance circuits where the appliance can be powered up whilst measuring the connection terminal voltage.
