Ok so I have read a lot that these damn volt and amp meters are a huge pain in the ass in these things and seem to be all that ever goes wrong and gives a lot of people issues. Me being one. I am not sure what's going on. When I use my multi meter to measure my current coming from my power supplies I'm showing 3.7volts. As soon as I plug the volt and amp meters in it drops to like .3 volts and the amp and volt meters won't show up. I can turn the set screw and eventually get the volt meter to show a faint number but it's showing 450-500 amps. Can't be right. Checked everything with my multi meter and showing 224 on my 220 circuits and 121.5 on my 120 circuits. Not to smart with electricity so scared to use my multi meter to check the 2 lines tied to the relay and main bus in the panel. Not sure if I can or I'll blow something up. Also not sure if I can use the amp meter to measure the amps across the shunt by simply touching both metal plates on it. Either way why would my volt and amp meters drop the supply voltage so much and not actually light up. To even get the volt meter to light up I have to turn the set screw a lot and then when I unplug the volt meter it's showing I'm supplying it with 9 volts. As the volt meter is 5 volt max I don't want to leave it there as I'm scared to burn it out however when it is plugged in it's only reading .9 volts on my multimeter. Anyone ever have this issue. I followed everything exactly as they showed on there website and I'm using the volt and amp meters they supply on there site.
