A multimeter, also called a VOM, is an ohmmeter, ammeter, and voltmeter combined in one case. A function knob can be turned to select the type of measurement to be made, such as volts, amps, or ohms. The multimeter's test lead connections to the circuit will depend on whether you are using it as a voltmeter, an ammeter, or an ohmmeter.
A Multimeter is an electronic instrument, every electronic technician and engineer’s widely used piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. There are two types of multimeters: Analog Multimeter: The Analog Multimeter or VOM (Volt-Ohm-Milliammeter) is constructed using a moving coil meter and a pointer to indicate the reading on the scale. Digital Multimeter: We mostly used a multimeter is a digital multimeter (DMM). The DMM performs all functions from AC to DC other than analog. It has two probes positive and negative indicated with black and red color as shown in the figure. there are some best multimeters for HVAC.
Where can I get copy explaining what the symbols mean on a sperry multimeter and how to use them. Regards Frank
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,

Based on the principle of the D'Arsonval galvanometer, the main function of a multimeter is measuring a circuit's voltage, current, and resistance.
The accuracy is the biggest advantage.
The main advantage of a digital multimeter over an analog multimeter is their accuracy.AnswerDigital instruments are not necessarily more accurate than analogue instruments (although they often are), but they are far more robust and, usually, far easier to read without error. A digital multimeter has no moving parts and is unaffected by gravity, so they can be used at any angle, whereas analogue instruments needed to be placed on horizontal surfaces and not subjected to vibration.
Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.

You can test a battery by using multimeter. Set the multimeter to the DC voltmeter setting and then place the leads of the multimeter across the leads of the battery. the multimeter will have a readout of the voltage.
The advantage of reading news paper is provided general knowledge and improve more english
An automotive multimeter, like any multimeter, can be used to test the voltage or current in some kind of circuit. As it is an automotive multimeter it is aimed more towards the used in a car.
A source of fresh water.
The analog multimeter has a wider range.
Yes it is possible to test a diode with a multimeter.
To check the IC by the multimeter, you have to make sure that the pointer points at the current. You can then connect the multimeter across the check the IC.
If there is a meter that shows volt and ohms then it is showing you the amount of voltage and resistance there is. However these meters are two separate devices with different uses.AnswerA 'volt ohmmeter' ('VOM') is a term used in North America to describe what is known, elsewhere, as a 'multimeter'. A multimeter combines the functions of a.c. and d.c. voltmeter, ammeter, and ohmmeter. The advantage of a multimeter is that it avoids the necessity of having to carry about six separate measuring instruments.
