Measure Inductance Using Multimeter

March 24, 2018

One method measuring inductance on a voltage current slope involves connecting the inductor to a pulsed voltage source with a duty cycle less than 50. 4 set the potentiometer to its maximum.

How to use lcr meter 4070 to measure capacitor inductance l resistance r is explained in lcr meter tutorial video.

Measure inductance using multimeter. A multimeter determines capacitance by charging a capacitor with a known current measuring the resulting voltage then calculating the capacitance. Measure inductance with an inductance meter of a multimeter. Yes great with a cheap rate we can build an inductance calculating meter.

Connect the leads to the lcr meter. 2 the diagram of the circuit that we are going to use for the test is shown above. Set the lcr to measure l or inductance.

Set the meter to 100 khz at 1 volt. This will enable you to read inductance. Most multimeter will measure all electrical properties of a component with the exception of inductance so you are left to your own devices.

Arduino is very cheap and the ic rate is about 120 rupees or 2. Using an oscilloscopes current probe read the peak current in amps and the time between pulses in microseconds. Multiply these amounts and divide the product by the peak current.

Steps 1 with the multi meter set to ohms measure the resistance between the terminals of the inductor. Check the display screen to figure out the inductance. Method 1 impedance comparison to resistor.

Connect a resistor of known resistance and the coil in series with the sine wave oscilloscope. To test the capacitor with a multimeter set the meter to read in the high ohms range somewhere above 10k and 1m ohms. There are several methods which we will discuss in this tutorial article.

How to measure inductance measuring with an lcr meter power the lcr meter and wait for it to turn on. So i decided to make an inductance meter using arduino uno ic atmega328p. To measure inductance with a multimeter simply switch the meter to the inductance meter and take the probes and measure across the leads of the inductor.

Review of lcr meter metro mtq 4070 is done. I designed a code for inductance meter using arduino programming software. If you have neither a more indirect way is to use an oscilloscope.

3 connect the circuit without plugging it to the power outlet. The best way to measure inductance for an inductor like a coil solenoid is to use an inductance bridge or meter.
