How to measure correct voltage and Current from proteous simulatin while using PWM

Hi All,
Please have a look at attached pic and guide me that how may i measure voltage and current across both batteries using ISIS simulation, As I want to change the duty of PWM to adjust charging voltage.

You'll have an easier time if you were to choose one particular reference point, and take measurements relative to that.

It appears that you have the batteries connected at the positive end. (Or rather, a diode intervenes.) Therefore your topmost wire can be the reference wire. The diode subtracts a fraction of a volt from readings taken on the leftmost battery.

Should a ground symbol be added to the wire where all those voltmeters have their negative leads hooked up? If not, then do your IC's have a power supply which has a definite ground to the power supply?
