    Megger LCB2500/2

    I recall biff55 really rating his that he got off ebay, fair play. I got one years ago, seemed fine for a while, but then it wouldn't make loop measurements, kept coming up with the 'Noise' symbol and take an eternity to give a reading, if at all, which was basically a random number. I've got a...

    Lighting Circuit Zs

    I must be confused about some wording, Light circuit R1+R2 is 1.84 Ze measured = 0.28 So if I do Ze +(R1+R2) I get 2.06 Maximum Zs allowed is 6.14 actual measured Zs is 0.88 This measured Zs is much lower than the max value, I know higher is not good but lower Zs leads to any problems ??
