Woah nice

This is cool! How much power does it draw? What kind of batteries did it use? How much does it weigh? Too bad you didn't show the measurements compared to today's multimeters and you didn't take any static "beauty shots". I would have liked to look clearly at the whole device and each detail.

It weighs 400gs w/o the batteries. I'm not aware of what kind of batteries does this device uses; i reckon something proprietary lead acid brick, but there is not much info on the Internet about this. I could not showcase how precise the measurements are on this, cuz I don't have a bench multimeter to compare it with. And comparing it with my handheld multimeters - it does not make much sense, because they aren't really high end, precisely calibrated instruments either. Thanks for the feedback tho. Appreciate it :)
