no, I havent springcrocus, but I would deffo consider it on pedigree alone,Robin/amprobe/fluke are among others the same in a multinational group, just different names,
easy way to do a full Zs is to simply link out the Line side of the RCD, bit of 1.5 is more than enough.
I really could do with a new meter, unfortunately money is not permitting just now, but if it was, then that would be one of my serious contenders,
unless I could find a reason not to I think that would be the one I would chose.
