I have a Quad. 10X probes. Like to monitor with my laptop the voltage on the hot side an the neutral to see what is doing on. Seem we did a 2 second drop here and there and like to see if I can get more info. Right not we have a APC fancy UPS saying there is a drop 10 minutes after the hour, most hours. Something on a timer, maybe a motor firing up, no idea but boss want to find it.
Any ideas, hoping the quad can handle the 240VAC and also record or dump text, rather than graphics. Also, will need to figure out how to tie in the ground hookup
