Meggar mft1730

aes2011 · Mar 19, 2012

When trying to obtain zs reading, rcbo keeps tripping...rcbo is a 40a type b wylex.

Meter set to L-PE and Z. Using 2 lead method.

Anyone else with the new meggar having same issue?

I take it that you have set the meter to the 'No Trip' setting?

What setting is the ' no trip' facility on, as there is not an actual setting saying 'no trip' on the 1730. Maybe on previous models but not this one.

You have to use 3 leads to do the no trip test.

You can do a two lead 'No Trip' Zs test.
Turn the big dial to Phase earth (the higher position on the green section), turn the smaller dial to the Zs test position (the lowest position on the green section), connect the green and red probes, and then connect to the conductors.
