Good enough for 'stralia. In the kV magnitude, you are probable dealing with high energy circuits where a few uA won't matter.

Maybe try reversing the DC polarity on the meter to see if that has an effect on the reading?

Would say PCB leakage would be a bigger factor, but low humidity inside will mitigate that. Try leaving one in the sun in a car for a day, then put in a plastic sealed bin to hold the high humidity in, and try again fast in the lab, to see just how much PCB leakage is.

Jeez, who would have thought a top tier multimeter manufacturer like Brymen would know what they were doing? 🙄

Very interesting! Yeah that's very good.

The fact that you see significant leakage at AC, but essentially none at DC, suggests that the MOVs have parasitic capacitance.
But I didn't do the math, so I don't have an estimate for how much. Maybe the datasheet mentions anything about parasitics?

Those graphs are for 20-23 C, I guess. But Australia can be sunny hot outside. Possibly meter lyied somewhere on the sunny window, get 50-60 C.

Too bad your Multimeter doesnt Amp to 11. (that`s where the headroom really matters.)
11*11 is where things get serious.

Wouldn't different values of MOV in series cause different voltage drops across them, possibly triggering lowest-rated one, which would trigger remaining ones in a cascading manner?
