		Multimeters are designed and mass produced for electronics engineers.
		Used as an ammeter, an analogue multimeter has a very low resistance and is very sensitive, with scales down to 50 礎.
		Most modern multimeters are digital and traditional analogue types are destined to become obsolete.

	Multimeter - Wikipedia, the free encyclopedia
		A multimeter is an electronic measuring instrument that combines several functions in one unit.
		A multimeter can be a handheld device useful for basic fault finding and field sevice work or a bench instrument which can measure to seven or eight and a half digits of accuracy.
		A multimeter may be implemented with an analog meter deflected by an electromagnet, as a classic galvanometer; or with a digital display such as an LCD or Vacuum fluorescent display.

	What is a Multimeter?
		Electricians and the general public might use a multimeter on batteries, components, switches, power sources, and motors to diagnose electrical malfunctions and narrow down their cause.
		A digital multimeter has an LCD screen that gives a straight forward decimal read out, while an analog display moves a bar through a scale of numbers and must be interpreted.
		The multimeter actually passes a small amount of electricity from its own battery through the circuit to measure resistance by comparing the voltage sent out to what it receives.

		Multimeters come in two basic flavors: the analog meter with a conventional electromechanical meter movement (the old kind with a pointer), and the more modern digital multimeter (DMM).
		They differ from conventional multimeters in that they have special current limiting provisions to prevent accidental firing of the detonators or blasting caps under test.
		Blaster's Multimeters and related test instruments are used in the well logging industry to check the continuity of electric detonator circuits commonly used in well shooting and perforating.

	Testing with a Multimeter
		For example, a multimeter can verify that there are about 120 volts in an AC circuit or that a 9-volt battery is fully charged.
		Multimeters are available in digital and analog models.
		The analog unit shown was $10 and the digital multimeter was $20, though you can pay $50 or more for more accurate models.

		A multimeter is used to make various electrical measurements, such as AC and DC voltage, AC and DC current, and resistance.
		It is called a multimeter because it combines the functions of a voltmeter, ammeter, and ohmmeter.
		Multimeters may also have other functions, such as diode and continuity tests.

	Electrical Theory for Boaters - Using a Multimeter - Nautical Know How
		Your multimeter, using the amperage scale, is the electrical equivalent of the paddle wheel and measures the flow through the circuit.
		The multimeter, when used to measure ohms, uses an internal battery to supply current (amperage) at a carefully regulated pressure (voltage) to the circuit being tested.
		Although it does not matter which leads from your multimeter you use to test AC current, when testing DC, it is imperative that you use the positive (red) lead on the positive (+) side and the negative or ground lead (fl) on the negative (-) or ground side of DC circuits.

	Digital Multimeter Measurement Fundamentals - Tutorial - Development Library - National Instruments
		Applying this example to a digital multimeter signal measurement, y is the reading obtained from the digital multimeter with x as the input, and b is an offset error that you may be able to null before the measurement is performed.
		For a noise-free digital multimeter, resolution is the smallest change in an input signal that produces, on average, a change in the output signal.
		Precision is a measure of the stability of the digital multimeter and its capability of resulting in the same measurement over and over again for the same input signal.

		A multimeter is an electronic (additional info and facts about electronic) measuring instrument (Instrument that shows the extent or amount or quantity or degree of something) that combines several functions in one unit.
		The most basic instruments include an ammeter (A meter that measures the flow of electrical current in amperes), voltmeter (Meter that measures the potential difference between two points), and ohmmeter (A meter for measuring electrical resistance in ohms).
		This is appearing in some high-end computer-controlled multimeters.

		The input resistance (ohms) of the digital multimeter can affect the accuracy of voltage measurements particularly when the resistance of the source voltage is comparable to the input resistance of the digital multimeter.
		When measuring the source voltage with a low source resistance (ohms), the digital multimeter returned a value that was accurate to within ±0.0005%, or 5 ppm, and the same source voltage with a high resistance returned a value that was accurate to within ±10%, or 100,000 ppm.
		The digital multimeter settle time is dictated by the measurement range, cable properties, source impedance, and change in input level.

		Used as a voltmeter, a digital meter is usually better because its resistance is much higher, 1 M or 10 M, compared to 200 for a analogue multimeter on a similar range.
		Used as an ammeter, an analogue multimeter has a very low resistance and is very sensitive, with scales down to 50 µA. More expensive digital multimeters can equal or better this performance.
		Most modern multimeters are digital and traditional analogue types are destined to become obsolete.

		As for multimeters, in addition to the usual (volts, amps, resistance, etc), for repairs (and trouble-shooting your own circuits) it's good to have one that sports a logic probe function, and a capacitance meter (less common) will allow you to identify unmarked caps, and to check that caps are functioning correctly.
		If you don't plan on running around with it, one of the old bench multimeters on ebay is a good idea the Fluke 8012A is an old standard, often selling for way under $50.
