1) Introduction multimeter (VOM)
Multimeter (VOM) is a measuring instrument indispensable to any electronic technician, best multimeter has 4 main functions of the resistor measurement, voltage measurement, DC voltage measurement AC and amperage. Advantages of the clock is fast measurement, test various types of components, see the release of the load capacitor, but this clock has limited accuracy and low impedance of about 20K / Vol so when measured in the circuit low flow we were brownouts.
2) Guide to measure AC voltage.
When AC voltage measurement has forwarded the scale of the elevator AC, to scale higher AC voltage to be measured one place, for example if the measured voltage AC 250V AC220V us to scale, if one voltage to a lower scale test the dramatic metal alarm clock, if the bar is too high, the metal to report inaccurate.
