| UT612 bad accuracy for the inductor, anyone experience? |

I have just bought UT612. I have a project using common filter inductor, value in hundreds mH range and try to measure it but value difference with same parts. For example I measure the Wurth 750318652 https://www.we-online.com/components/products/datasheet/750318652.pdf, the value on the manufacturer is 100mH at 10khz, but I measure with 10khz it show 25mH. And I try to measure some filter it show 180mH for 100mH value by manufacturer, they write it is 1khz measurement: https://www.lcsc.com/product-detail/Common-Mode-Filters_XR-XRUU9-8-100mH-V_C5358173.html. So the error rate is 80% |O So I am very disappointment about the UT612. I do it wrong or it is limitation of this device? Before by the UT612 I just read in the front page show range from 20uH-2000H and bought, it is my fault. The range is not for all frequency. I also try some power inductor like 33uh, 22uh and it accurate. But anythings bigger than 10mH show ridiculous value. |
