Transcript of THE MULTI-TESTER

multi-tester 1. ANALOG MULTITESTER

A multi-meter or also known as VOM (volt-ohm-meter) is an electronic measuring instrument that combines several measurement function in one unit. It measures voltage, resistance, and current in electronics & electrical equipment 2 kinds of multitester Uses a moving pointer and a printed scale to indicate values of voltage, current, or resistance.

Analog instruments use a moving coil meter movement. The DMM (digital multimeter) has become a very popular test instrument.
The digital value of the measurement is displayed automatically with decimal point, polarity, and the unit for V, A, or Ω. PARTS OF ANALOG MULTITESTER Front panel Dial pointer Zero ohms

Panel Indicator Shows each function and setting range to turn dial to. Meter Dial Turn dial to change functions. Turn dial to OFF position after use. It is most applicable when there is a need to monitor rapidly changing variables of safe or normal levels of operation and to do at a glance . Advantages of
