How do I measure inductance at home? I have different inductance coils, how can I measure them more accurately?
Moreover, there are inductance coils with a ferrite core and without ferrite, their inductance is much less than with ferrite
To measure inductance I use two devices available to me, these are the FNIRSI DSO-TC3 and DT 71 testers. The DSO TC3 tester can measure inductance from 10 μH to 1 mH, and the DT71 tester can measure from 1 μH to 50 mH. The DT71 tester is well suited for measuring inductors without ferrite.
Check. I have a choke with an inductance of 150 μH. The DSO TC3 tester will show 160 μH. DSO TC3 measures coils with high inductance well
The DT 71 tester will show 173 μH. The difference in readings is called the error.
When measuring coils with low inductance, the DT 71 tester shows itself well here. I have a choke with an inductance of 20 μH. The DSO TS3 tester will show 40 μH.The measurement error is very large
The DT 71 tester will show the inductance more accurately, namely 20.5 μH.Here the measurement error is low, it is just great for home measurements
All low-inductance coils I measure only DT 71
