I've got a drawer-full of "ballpark accuracy" LED and LCD meters. Wanna get one that reads 12.4 volts when voltage is really 12.75? Got one for you! Wanna get one that reads 13.08 when voltage is 12.86? Got that too!
Five meters, 110.7 VAC range from 101.2 volts to 122.4
Don't wait! Fix your voltage NOW! Too low? Gotcha covered. Too high? No problemo! What you see is what you get!
No, they don't have a pot on the back.

I did calibrate my "master" DMM on a $14,000 Tektronics Oscilloscope. So it's a decent reference for the next couple of months.

Just kidding! You have overdrawn seven times at $35.00 a whack.
Lights go out? Too low of voltage.
Smell sulfur? Too high of voltage.
