Multitester - Functions and Parts -- Electronics HW

The Multi-tester / Multi-meter or sometimes called VOM (Voltmeter, Ohmmeter, Milliameter) is a hand-held device that can be use to check resistance, continuity, and voltage in electrical components.

FUNCTIONS:

- measures the following:

• Voltage, alternating and direct, in volts.
• Current, alternating and direct, in amperes.
• Resistance in ohms.

- A multimeter can be useful for basic fault finding and field service work or a bench instrument which can measure to a very high degree of accuracy. They can be used to troubleshoot electrical problems in a wide array of industrial and household devices such aselectronic equipment, motor controls, domestic appliances, power supplies, and wiring systems.
