Once you have the dial on your volt meter set to measure voltage, simply touch the black lead to the negative (-) terminal on your battery and the red lead to the positive ( ) terminal on your battery.
Simple Measurement Circuit. This shows how to connect a Voltmeter for measuring voltage and an Ammeter for measuring current. Thinking about how this works may help you understand voltage and current a little better. An ammeter needs to measure the flow of charge, so it is in series.imple Measurement Circuit.
