Multimeter
Overview:
Multimeter is an electronic measuring instrument that combines several functions in one unit. The most basic instruments
include an ammeter, voltmeter, and ohmmeter.
Other features available in some units:
- A continuity tester that beeps when a circuit conducts.
- Digital output (as a number, rather than a scale reading) of the quantity under test.
- An amplifier to sense small voltages, currents and high resistances.
- Measurements of inductance and capacitance. This is helpful to test components, and therefore much used by technicians that must build and
repair equipment.
- Tests of diodes and transistors.
This is popular with technicians who have to fix broken equipment.
- Scales and sockets for temperature measurement with standard thermocouples.
- An intermediate frequency oscillator, a detector and an audio amplifier with
a speaker, to diagnose and tune radio circuits. This used to be standard on some Russian
models. It is an inexpensive compact substitute for an oscilloscope. It
permits one to hear a signal, rather than see it.
- A slow oscilloscope. This is appearing in some high-end
computer-controlled multimeters.
- A telephone test set.
- Automotive circuit tester.
- Record high and low voltage snapshots
