Hi,
I usually buy digital panel meter for measurement of AC line voltages (90- 250 VAC), from New Delhi, India.
These are open frame type, and consist of an ICL 7107 and 3 seven segment digits and some passives. The panel meter needs to be connected to a small transformer and the voltage sense pins are given directly to the line voltage that is to be measured.
I would like to know have the circuit diagram for such a unit.
I could always trace it myself, but If the circuit is readily available it would be very helpful indeed. I have looked in the internet but they do not give one specifically for AC line voltage measurement.
thanks
