Basically you put the 1 Gig resistor in series with the + lead of your DMM, and multiply the corresponding reading by 100. Make sure you're in the 60V or 600V range, the input impedance of the 87V isn't exactly 10 Meg in the 6V range. This is perfect. Was able to dial mine in nicely to 400V with th...

Will do and thanks!

On my raspberrypi3B I had to use ttys0 instead of ttyAMA0 minicom -b 9600 -o -D /dev/ttyS0 This yielded output: Welcome to minicom 2.7.1 OPTIONS: I18n Compiled on Aug 13 2017, 15:25:34.
