Anyone know how to get ZE from Scottish Power
I am just getting the run around….
now that analogue scale topping out at 20kA on the boskiest range, makes it clear that is the ‘here be dragons’ part of the curve, as all the high current lines on the scale are compressing to the full scale deflection. (look at it and you can easily tell 3kA from 3.2kA, but the gap is about the same as 15kA and 20kA try and I challenge you to separate 18kA and 19kA with out worrying about the thickness of the needle and parallax.)
A digital meter hides that increasing uncertainty it the low resistance end from you, but really it is still there.
I suggest the high range on this is not really high enough for the OP, and a larger test current more than the 20-30 or so amps this uses is needed.
