Current Measurement Using Multimeter

The neat thing about a multimeter is that unlike a ruler watch or scale it can measure different things kind of like a multi-tool. On some meters both are fused.

This measurement can give you critical information about the circuit but also comes with some warnings.

Current measurement using multimeter. Some offer frequency and temperature measurement. The most preferred multimeter for measuring direct current is the digital multimeter. Thats why the multimeter that is used by electrical professionals are made to have very low resistance.

Measuring current is different. Whenever something in your circuit isnt working the multimeter will help you troubleshooting. This range is sufficient for measuring current in LEDs.

Our Multimeter can measure both AC and DC voltages. Using a multimeter to measure current may not be the most frequently used function but it can be very important. To measure DC Current set knob of the Multimeter to DC Current measurement.

In this case I measure volts and O using the input 4 but current is measured using input 1 and high amounts of current through input 2. A multimeter configured to measure current on the high amperage setting red probe in the A socket rotary dial turned to the A setting Note that whether either of the two amperage sockets have an internal fuse varies meter to meter. I set the range to 200mA and connected the Multimeter as per the following circuit.

You can also use it for checking continuity of wires and fuses. The two cables connect the LED cathode. Shown below is a typical multimeter face layout.

To measure AC current with a benchtop multimeter select the I AC mode connect the positive probe to the mA port for measuring small currents or the 10A port for measuring large currents. Basic introduction to using a digital multimeter to measure current in a simple circuit. Image showing multimeter probes connected to LED circuit for measuring current Multimeter works like an ammeter when ammeter.

We need to put the multimeter in series making current flow through it. A multimeter will be an essential tool when troubleshooting or testing the direct current. As a matter of fact for an amps measurements the aversion of your multimeter should be below 1 ohm.

Current can be measured in the range ofmilliamperes 400mA max to Ampere 10A max as shown in the above image. This particular Multimeter can measure DC Current from few µA to 200mA. All most all electronics devices work on DC voltage Conventional AC will be converted to DC and hence DC voltage is the most measured parameter.

In this case I have a potentiometer that lights a LED. Multimeter has different procedure for measuring current. There are two different Voltages in general that can be measured by the Multimeter.

A typical current measurement can be made as shown below. Both AC and DC currents can be measured with a multimeter by connecting the meter in series with the circuit in which current being measured provided the current in that circuit is limited or controlled by a load or appropriate values of resistance. On others only the high amperage 10A socket is fused.

A multimeter allows you to understand what is going on in your circuits. Physics teacher Ronan McDonald demonstrates how to use a multimeter to measure current. There are two types of multimeters both the analog and digital multimeter.

To measure current lets build a little circuit. A multimeter can measure other quantities besides amps but today we are just concentrating on ampmilliamp current measurements. Current is what alerts you that something dynamic is happening in the circuit electricity is moving.

Like DC current measurements AC current must be measured in series with the circuit to allow the electrons to flow through the multimeter in order to take the measurement. A voltmeter ohmeter and ammeter and in some cases continuity. One is DC voltage and the other being AC Voltage.

However to take accurate current measurements with a multimeter the aversion of your multimeter must be very minimal. When using a multimeter to measure current the only way that can be used to detect the level of current flowing is to break into the circuit so that the current passes through the meter. A multimeter is a handy tool that you use to measure electricity just like you would use a ruler to measure distance a stopwatch to measure time or a scale to measure weight.

It combines three essential features. Basics in current measurement using a multimeter. Also depending on your multimeter you might need to change the entry point for the cable.

Current Measurement using Multimeter. A digital multimeter or DMM is a useful test instrument for measuring voltage current and resistance and some meters have a facility for testing transistors and capacitors. A multimeter is a measurement tool absolutely necessary in electronics.

The unit of measure for AC current is amps AC. Digital multimeter performs all standard analog-meter measurement functions of AC and DC. Digital multimeter has generally replaced the analog-type multimeter as the test device of choice for maintainers because they are easier to read are often more compact and have greater accuracy.

Connect the negative probe to the INPUT LO port. Although this can be difficult at times it is the best option. If you are measuring relatively low value AC currents or DC currents you will likely be using the ampsmA measurement function of a multimeter.
