I need to do a ze reading on a pme system. What's the maximum allowed reading and is it still a three lead test as the earth comes through the neutral. Really appreciate any help. Not had to go this before. Thanks

 

[telectrix]

max. is 0.35Ω, and it's a 2 lead test on hi-current. don't forget to dis. the earthing conductor for the test (after isolating the installation).

Wow Tel, you took all the fun away from the OP. Now he won't be able to open the OSG and look it up

 

[telectrix]

ah, well, i'm feeling generous today.

You big softy...

I am worried that someone has asked for the max reading before doing the test its the first thing that hits you as you open the OSG mind as long as they don't ask how to do it as well

On Kewtech KT65(maybe other Kewtech,too) it's a three lead test. Number of leads is dependent on tester

Not really about trolling. It's just one of those figures that normally sticks in the mind the first time you have to know it.
