How to read milliamps on a multimeter

Plug the red probe of the multimeter into its positive port. Check the two test leads and probes for damage such as cracked insulation and heat damage.

If the reading is in amps multiply by 1000 to convert to milliamps.

How to read milliamps on a multimeter. Multimeters can function as ammeters measurers of current and you can use the meter to read the number of milliamps flowing through a circuit. This process usually requires connecting the probes to the appropriate ports breaking the circuit so the current can flow to the multimeter choosing a suitable setting on the meter and then connecting the probes to the. Moreover how do you find milliamps.

Insert Watts-hour Wh and voltage V and click on Calculate to obtain milliamp-hours mAh. Formula is Wh1000V mAh. For example if you have a 15Wh battery rated at 5V the power is 15Wh 1000 5V 300mAh.

One may also ask what does 200m mean on a multimeter. 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 a reading to three decimal points. 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. Consequently place the red lead on your multimeter to the circuits uppermost part and then restore the energy to the circuit and your multimeter should show some figures.

If it starts with 1 to 10 you should then know you measure amps but if the begins with a number that is followed by a decimal you then are measuring milliamps. Assuming you have it hooked up properly then you just read it directly. On the 10 A scale it means that what you read is in amperes and it will measure up to 10 A.

If you but it on the 200 mA scale then what it reads is in milliamperes and it will read up to 200 mA. This is because we dont know how much current were going to be measuring so by inserting the probe into the input jack for milliamps we might cause the fuse to blow up. 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. No one likes to do it but you might want to actually read your multimeter instruction manual if it hasnt been thrown awaylost by now. To read current plug the black meter lead into the COM jack and plug the red meter lead into the mA or 10A jack.

Using the mA jack you can measure currents up to 200 mA on this particular meter. Therefore the full-scale readout for this range will be about1 200 milliamps. If more than 200 mA of current passes through the multimeter on this range the multimeter will display an over-range indicator instead of the measured current.

This means that a display of 20 or 20 indicates a measured current of 2 milliamps not 2 amps. Alternatively use the Current setting and select a range to measure in milliamps. Check the two test leads and probes for damage such as cracked insulation and heat damage.

When youre satisfied that the leads and probes are in good condition connect them to the multimeter. Look at the number next to the pointer if all the digit positions are filled that would be the maximum reading on the display. The decimal marks the boundary between one thousand multiplier an the next betweem mA and uA or between A and mA.

Now interpreting multimeter symbols starts by understanding the decimal adjustment concept. After all its a wasted investment if youve just got yourself the best multimeter and cant read the degrees of units. So do you know how to read milliamps on a digital multimeter.

Can you remember the basic skills of reading SI units. Physics teacher Ronan McDonald demonstrates how to use a multimeter to measure current. How to Use and Read a Multimeter to Calculate Power A multimeter does not directly measure power or watts.

Instead an appliances watts can be calculated rather simply by measuring the voltage and the current and then multiplying them together. 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. A multimeter combines all these functions into one device.

It has a dial on the front so you can select the function and sensitivity you need and an LED screen that displays the readout. To measure voltage across a circuit element you have to connect the leads of the meter in parallel with the element. A multimeter combines all these functions into one device.

It has a dial on the front so you can select the function and sensitivity you need and an LED screen that displays the readout. To measure voltage across a circuit element you have to connect the leads of the meter in parallel with the element. 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.

The term milli is defined as 11000 so when you say 50 milliamps or 50mA that means 005 amps. You can now conduct the test confidently by yourself if you follow the above guide. Note that if the reading on the screen of the multimeter is below the range setting ie the range setting goes up to 3A and the reading you get on the screen is less than 03A you will have to shift the multimeter to read mA.
