laser measuring instrument How Does a Multimeter Work?
Multimeter is a tool used to troubleshoot electrical and electronic circuits.They are also used to check the voltage to ensure the correct level of work.The most common models measure voltage, current, and resistance.More expensive models also measure capacitance and inductance.1 m is a measuring instrument.Current measured by ammeter;The voltmeter measures the voltage between two points;There is also an ohrazer to measure the resistance.The multimeter combines these functions into an instrument. The multimeter can be used to measure voltage, current and resistance in circuits using resistors and capacitors.The ammeter function of the multimeter measures the number of electrons passing through the given point within a certain period of time.This measurement is the measurement of current in units called amps.To understand what amps are, the rated power of a typical home breaker is 15 or 20 am amps.The multimeter can be used to check how many amps the household appliance draws to see if it draws too much current, causing the circuit breaker to turn on.The voltmeter function of the multimeter measures the potential between two points and is measured in volts.For a 9-Volt battery, the potential between the positive and negative terminals of the battery is 9 volts, which can be checked with a multimeter.This is often useful when the battery is suspected to be close to the end of life.The ohrazer function of the multimeter measures the resistance of the current.This measurement is in ohms.If the circuit is shortThe resistance is zero or close to zero ohms.If a circuit is open, it has an infinite resistance and no current flows.The multimeter has the ability to measure current and voltage in two different modes of AC or AC, DC or DC.The standard for home voltage sockets is AC.Different countries have different standards for family.C.Voltage, which is why many travelers find a fault with their 120 AC voltage hair dryer when plugging in a socket abroad.If the voltage is unknown, it is helpful to check the voltage with a multimeter using the AC voltmeter function.The battery supplies DC current when the home supplies AC current.When current measurement is performed, in order to obtain an accurate measurement, the multimeter must be set in the correct functional AC or DC.
