I have found an example of where more current is more stable than less current, on my present project, fuel gauge, I am finding that as I test the circuit by attaching my DSO-2150 usb scope to the circuit, it changes everything, the scope leads have a 1 Meg input resistance and 25pf to ground and my Fluke DVM has an 11 Meg input impedance. If the resistor used in a circuit, are in 10s of K ohms and only a few 100s of K ohms, my scope and meter will have very little effect. Mike's design works great on Spice and seems to be working, but I can't get it to work and can't figure out why because of the test equipment loading.
