Accuracy is less important it it must be acceptable = to measure the same values for the same coils five minutes later. By measuring the phase difference, you can work out the capacitance (or inductance) of the component at that frequency, as well as any equivalent series resistance (ESR) of capacitors. Initially I used a DMM as the display device, but on a whim I tried hooking up a moving-coil meter. I've just finished a little Arduino project. An inductance / capacitance meter by Phil Rice, VK3BHR. ESR Meter / Capacitance / Inductance / Transistor Tester Kit ESR Meter kit is an amazing multimeter that measures ESR values, capacitance (100pF - 20,000uF), inductance, resistance (0.1 Ohm - 20 MOhm), tests many different types of transistors such as NPN, PNP, FETs, MOSFETs, Thyristors, SCRs, Triacs and many types of diodes. Due to high demand and severe weather delays, orders placed the week of Feb 2/1 may not ship immediately. It’s a shield for the Arduino Uno that lets you measure inductance. It's a shield for the Arduino Uno that lets you measure inductance. To my surprise, it actually worked just fine, 1K in series was sufficient to allow a useful calibration and didn't overload the drive capabilities of the last gate in the package. 21 thoughts on “ Using An Arduino To Measure Inductance ” Weasel says: ... For the cost, this is fine, but don’t expect anything even comparable to a real LCR meter. Initially I used a DMM as the display device, but on a whim I tried hooking up a moving-coil meter. Arduino inductance meter I recently bought a little LC meter on EBay. LCR meter. 4 resistor test ranges, Resistor range is from 0 ohms to 2 Mohms. I’ve just finished a little Arduino project. Arduino Inductance Testing Posted on June 10th, 2014 in Arduino , DIY Equipment , Electronics , Test Equipment In yesterday’s post about the progress on my big switch mode supply I mentioned that I was going to try building an Arduino based inductance meter based on the basic and straight forward design from Shadi Soundation .
