Measuring Small Inductances with Digital Multimeter Smart Tweezers

// September 3rd, 2010 // No Comments » // Smart Tweezers Tricks and Tips

Smart Tweezers are capable of measuring inductances as small as 1 micro Henry with accuracy of about 5%. However, it should be kept in mind that Automatic mode is not suitable for this type of measurements and gives results roughly 10% lower than actual values.  Setting the Test Frequency to 10 KHz resolves the problem. Another thing has to be noted: inductive components are designed for a use at specific frequency and this frequency is shown in the component datasheet. Very often this frequency is much higher than that used by Digital Multimeter Smart Tweezers and therefore values measured at 0.1, 1 and 10 KHz may significantly differ from the nominal value of the component.
