I like creating electronics related YouTube videos. I mostly buy faulty gear from Ebay and make a repair video of it, but it's expensive and so with your help maybe I can continue to do so. Your support would be greatly appreciated.

My Philip Harris Mains AC Current Meter has 2 modes but only 1 LCD, so I decided to modify the panel and incorporate 2 LCDs.

In the video I take the meter apart, take some measurements of how the existing DVM is interfaced, draw up a partial schematic then get to work converting the circuit and adding in the 2nd LCD.
