Parts of multimeter and their functions

A basic multimeter measures resistance, voltage and current. More advanced models can measure capacitance, inductance, and temperature. A few multimeters have illuminated displays for better viewing in low light situations.

The selection knob allows the user to set the multimeter to read different things such as milliamps . SYSTEMS PLUS COMPUTER COLLEGE Resistance Ohmmeter : is an instrument.

It is mechanically connected to the moving coil.

It indicates the measured values on the multimeter.

RANGE SELECTOR KNOB-(selector switch) makes it possible to select different function and range of . Learn what are the parts and function of the Voltage Ohmmeter and its parts and functions. Until you will learn how to use this equipment. Create animated videos and animated presentations for free.

Voltage: The options for measuring voltage range from. Current: The options for measuring current range from 20µA. The applications of ammeter mainly involves in various electrical and electronic projects for the purpose of components testing and also used in different measurement applications in multimeter. Temperature and Environmental Applications.

There are broad applications for the use of DMMs particularly for processes involving electrical engineering design, maintenance, quality control, inspection and any application requiring electrical servicing and diagnostic testing. Multimeter Selection and Functions. A typical multimeter can measure voltage, current, and resistance. Technicians, engineers and scientists use multimeters to measure electricity and electronic components.

Components inside are completely different from each other. Starting with analog multimeter , it basically has one CT and one PT along with many transducers. These analog multimeters are bulky and difficult to handle so their usage is very limited. COM Input Terminal: Common groun used in ALL measurements. V omega Input Terminal: for voltage or resistance measurements.

A Input Terminal: for small current measurements . A multimeter is has three parts : Display. Two probes are plugged into two of the ports on . Digital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance. Test leads are flexible, insulated wires (red for positive, black for negative) that plug into the DMM. They serve as the conductor from the item .
