I have no more resistance at hand now.
I have some.


1. 50G:




2. 100G:




Looks good to me.

It doesn't however see them (shows OL) at 1000V and below -- needs 2kV or more to measure either of them.


p.s. one of the best of my impulsive purchases so far. Very rarely needed, but it's an absolutely essential bit of kit, and at this price it's a no-brainer.

Those resistors have a declared voltage resistance of 2000V
FNIRSI 1013D Always provide a picture or video with the problem where the parameters of the oscilloscope are visible, and a picture of the diagnostic screen with the values.

I think I heard some sound from the 50G resistor when I tested it at 2.5kV. Might've been a spark or arcing. No critical damage, though, it seems: still measures 50G. Not a big deal in any case: my only use for these resistors is to test this megohmmeter :).

My MH!2 behave in similar way and the the output is negative.
below is the  image of out at 1000v mode.
another strange thing about MH12 is it's input resistance in meter mode.
the input resistance is about 10M but when the polarity of probes changes it  reduce to 5M. |O
