An instrument that reads and measures the values of several different electrical parameters; such as, current, voltage, and resistance.

1. An instrument that uses semiconductors or electron-tube circuits to measure resistance, electric current, and voltage.
2. A multimeter that uses semiconductor or electron-tube circuits to drive a conventional multiple-scale meter.
3. An apparatus that employs the characteristics of an electron-tube circuit for the measurement of electrical quantities, at least one of which is voltage or current, or a single calibrated scale.

When a digital display replaces the moving-coil meter, it is called a "digital multimeter".
