TI has published a reference design "LCR meter analog front end reference design" https://www.ti.com/tool/TIDA-060029 Following text is copied from TI site: This reference design, TIDA-060029 demonstrates an analog signal chain solution for LCR Meter applications using an auto balancing impedance measurement method. Features * Measures wide range of components (L, C, R) with impedance values ranging from 1 Ω to 10 MΩ * Frequency of operation up to 100 kHz * Tested at 100 Hz, 1 kHz, 10 kHz, 100 kHz * Impedance accuracy of 0.1 % * Inherently stable operation of the signal chain |

As far as the kelvin cables/clips/etc, that's a non issue for me. |

What are main differences between to22 and DE-5000? To me to22 looks a bit more appealing due to the color screen. |

Check their specs and do a comparaison ? https://www.deree.com.tw/de-5000-lcr-meter.html http://hantek.com.cn/products/detail/16180 the t011 is an 1832c the t022 is an 1833c They seems to have the same ranges, i work with 12,000 uf capacitors in banks of 2 or 4 ... have to separate them if i want to do measurements. EDIT arr some web lag loll 20 millifarads are the top capacitor range = 20,000 uf, i would like a 100,000 uf top range :( The biggest difference for me is the integrated usb link in the to22, the de-5000 need an added interface, but generally have all the input dongles ... Of course you have colors loll Edit : i've seen some country have big import charges and added taxes, it will influence the total amount in a big way ??? Your wallet will talk loll The lowest price i've seen for the Hantek are 182$ usd for the to22 on AliExpress and Banggood, Ebay seems to follow this trend. The DE-5000 kinda disspapeared on some websites ? The DE-6000 is a tighter specced model, not worth the $$$ price difference You have the ET430 series who seemed very nice too, but high priced to my taste, they seems a rebadged version of tonghui and another one (blank memory loll) ANNND where back in a circle, too many models to choose. Would be nice to poke in the FW of the TO22 to see if we can hack a TO11 / 1832c into the TO22 / 1833c, there is a started thread fo the TO11 here with a dumped FW of it. https://www.eevblog.com/forum/testgear/hantel-lcr-1832c-unlock/ |
