A multimeter is a device that can take multiple types of measurements.   Multimeters vary in what they can measure based on their manufacturer.  Multimeters exist that can measure some or all of the following: Volts, Ohms, Amps, Diode Test, Capacitor Test, Transistor Beta, Temperature, Frequency, Pulse Width, Dwell, RPM, etc.

Not all digital multimeters are the same.  What makes one meter better or worse than another?  This chapter will answer that question and more.

Shown below is an antique voltmeter, (model 2952) from Sears, Roebuck and Co. in the 1940's.
