How to measure milliamps with a digital multimeter

The basic DMMs can measure amps volts and ohms as the older analogue meters did but with the ease of incorporating further functionality into an integrated circuit many digital multimeters are able to make a number of other measurements as well. On the 200mA scale you are displaying milliamps so as you suggest a current of 1A would be off the scale.

Plug the black output lead into the meters common jack and the red output lead into the meters milliamp or mA input jack.

How to measure milliamps with a digital multimeter. So 1 MΩ is 1 megaohm or 1 million ohms. Reading Milliamps With a Digital Multimeter. The process for reading current on a digital multimeter depends on your specific multimeter but it is similar across most devices.

Turn on the meter and insert the probes into the appropriate spots. You are measuring milliamps if it begins with a zero and a decimal point. If that number is below 0400 you will receive a more exact reading by changing the red lead to the mA jack and changing the multimeter to the milliamps range.

Fluke digital multimeters sometimes give. However some digital multimeters may not have a separate connection for measuring milliamps. For better readability it is recommended that you get one that does.

Now turn the switch to the correct measurement since were measuring current so select the ampere option. You can learn easily how to check the milliamps through multimeterchecking a tank level sensor whose output is 4 - 20 ma. Just need to connect it in series.

To measure a 4-20 mA loop signal with multimeter or loop calibrator. Check with operations before initiating the measurement. Access the signal wires typically by removing the cover on transmitter.

Select the mA dc measurement function and connect the test leads for mA measure. Watch out a lot more about it. The term for a thousandth of an amp is a milliamp so when a digital meter measures current in milliamps its actually measuring thousandths of an amp.

Switch on the multimeter. If it has a Battery Test feature use it before proceeding further and replace the battery if it fails the test. Write down the current reading from the multimeter screen and start the stopwatch.

If the reading is in amps multiply by 1000 to convert to milliamps. For example assume the current reading was 200 milliamps. Plug the red probe of the multimeter into its positive port.

Furthermore how does a multimeter measure AC and DC current. Some digital multimeters DMMs also include m. First insert the black lead into the COM jack.

Next insert the red lead into the VΩ jack. Connect the test leads to the circuit. Black lead first red second.

Read the measurement in the display. Basic introduction to using a digital multimeter to measure current in a simple circuit. Digital multimeters or DMMs can measure a variety of different parameters within an electrical circuit.

The basic DMMs can measure amps volts and ohms as the older analogue meters did but with the ease of incorporating further functionality into an integrated circuit many digital multimeters are able to make a number of other measurements as well. Physics teacher Ronan McDonald demonstrates how to use a multimeter to measure current. On the 200mA scale you are displaying milliamps so as you suggest a current of 1A would be off the scale.

It would also be in danger of blowing the fuse that is normally present in the current-reading circuits in a multimeter so always work down the scales 10A 200mA 20mA 2mA etc if you dont know roughly what current you are measuring. Write down the current reading from the multimeter screen and start the stopwatch. If the reading is in amps multiply by 1000 to convert to milliamps.

For example assume the current reading was 200 milliamps. How to measure milliamps with a fluke digital multimeter. How to measure milliamps with a fluke digital multimeter.

1 post Why we dont use 2-20mA 1-20mA 3. One of these is meant to measure resistance and voltage the other to measure amps and finally another one to measure microamps and milliamps. Integrated into a multimeter is a dial that carries out different functions such as testing resistance AC and DC voltage as well as continuity.

Moreover the multimeter features numerous settings on. The selection knob allows the user to set the multimeter to read different things such as milliamps mA of current voltage V and resistance Ω. The LCD is embedded on the PCB and is interfaced through pin-outs on the PCB itself.

A transparent plastic casing is over the LCD protecting it from the scratches. Plug the black lead wire that comes with the multimeter into the socket on the front of the machine marked COM which stands for Common. Plug the red lead wire into the socket marked VΩmA.

It is usually the middle one. The top socket marked 10A is rarely used. Measure the voltage between the USB ports 5V red wire and ground black which on a type A connector are at the far left and far right sides.

Then Connect a 10 ohm resistor rated at least 5 watts between those wires and measure the voltage again. It shouldnt drop more than about 5. You need to be in line to measure current.

You can disconnect the wire to the cathode then use your DVM in CURRENT mode. OR Put a 1 ohm resistor in that location and use the DVM to measure the VOLTAGE drop across it. 1 mv 1 ma current.

To use these clamps with a Fluke Digital multimeter the meter must have a milliamp input jack. Plug the black output lead into the meters common jack and the red output lead into the meters milliamp or mA input jack. Set the meters function switch to read ac milliamps.

Place the clamp jaws around only one conductor of the circuit to be tested. Milliamps are tiny fractions of amperes. Each one is 11000 of an amp.

This is measured in ohms. On analog multimeters theres a scale on the display labeled as ohms resistance or the ohm.
