--- Quote from: pope on December 13, 2023, 10:35:41 am ---The matrix-5200 quality-wise looks like a much better meter than the TE. I ws eyeing on it for a few months and I could get it from EU. However, it's much more expensive and it has less functionality than the TE (i.e no continuous frequency, voltage, no auto-select, etc..) But it definitely does look of much better quality. --- End quote --- Yeah good call out, I realized that when I dug a bit more into specs. I can get the ET3502 for the same price as Matrix LCR-5200, so I think, as you say, better deal because it is continuous frequency. The ET3502 seems to me to be in the same category as the Matrix LCR-5200. |

--- Quote ---I've also had a look on eBay and Hioki 3522/Hioki 3532 is also options, but quite a bit more money, still I suspect a much better meter. I've got a seller that is offering the Hioki 3532 for $700 (made an offer type thing) which seems to be the best deal I'll be able to get (turns on and works, "unable to test completely") --- End quote --- The hioki is on another planet, in comparison to the mentioned meters here before. ;) That´s why I´m still trying to restaurate my 3532-50(display problems, touchpanel defective). |

It does look better deal but bear in mind that we're dealing with some not-so-known Chinese brands here so take everything with a grain of salt... |

My repair skills are not anywhere near yours (hobbyist vs professional doing this every day alone tells me I'll probably struggle a lot more) Funny enough some sellers are offering this same meter with a broken display for not much less than the working products. Planet eBay is a strange place. --- Quote from: pope on December 13, 2023, 11:56:49 am ---Well, quite frankly I have no idea whether it's better deal. It all comes down to real specs.

The ET34/35xx is their "hobby" version (my opinion). I'd be surprised if the quality weren't better on the ET35xx series. |

We utilize "Meters" to measure device and circuit parameters, like voltage, current, capacitance, resistance, inductance and so on, and why we employ various precision Bench Type Lab Grade DMMs and LCR Meters (as well as handhelds DMMs and LCR meters, for less precision GP use). The Hioki IM3536 is our "In house reference" for LCR use, and also the Tonghui TH2830. These are high quality Bench Lab Grade LCR meters that allow comparison measurements. We have some precision (0.01%) Caddock and Vishay Resistors for reference, but no precision capacitors. However we have stable Polystyrene, Mica, and NP0/C0G types that we've kept measurement records and periodically compare with the Hioki and Tonghui meters. We feel this is necessary even with these quality well known Lab Grade LCR meters, which are also compared with 3 KS34465A, and a DMM6500 (also HP34401A, AG34401A and SDM3065X). With these ET brand questionable LCR meters, how does one convey confidence in measurements? Precision resistors are available and inexpensive, however reference capacitors that can verify to the "claimed" ET precision levels are not readily available, and likely very expensive. As a side note, the mentioned ET reversed BNC arrangement when using Fixture based Kelvin Clips like the TH26011 or B&K TL89K1 will reverse the polarity of the internal DC bias as "seen" at the colored and labeled Kelvin clips. So one must remember to reverse the Kelvin connections when using internal DC Bias. Anyway, these ET LCR meters seem questionable for any serious use, altho as always YMMV. Best, |
