voltmeter  (vltmtr)
An instrument used for measuring the difference in voltage between two points in an electric circuit. Voltmeters typically make use of an ammeter that measures current flow across a known resistance inside the voltmeter; direct-current voltages can then be determined by Ohm's law. Digital voltmeters employ A/D converters to provide the numerical value of the voltage displayed. Compare ohmmeter.

You will need: citrus fruit (like oranges or lemons) or a potato something copper (like a nail or coin or metal strip) a piece of zinc (about the same size as your piece of copper) 2 wires with crocodile clamps a small LED light or a voltmeter 1.
Calibrate the linearizing amplifier with a decade resistance box or RTD simulator connected to the input and a high-accuracy digital voltmeter connected to the input.
The second step is using the correct caliber of voltmeter and test leads-and to take some simple safety precautions.
