Small houseboat system that I put in a few years back needs a gas gauge other than the original E-meter. Operator issues require something simpler. System uses Trace T40 CC, but can't seem to find the lcd display that was an optional accessory - anybody have one of those or other ideas for a

I'd suggest a differential voltage probe and a current probe with a two channel scope. Observe both waveforms simultaneously. Phase shift (PF), amplitude, waveshape, harmonics, etc all at one time. Most digital scopes you can store the waveforms, download them to your computer, or just take
