content: I recently decided to add a LCR meter to my measurement tools. In my searching these two meters looked to be competitors, with the East Tester having slightly better specifications. I could not find any good comparisons between them, so I did what anyone with a case of TEA syndrome would do, and purchased both. After using them, I believe that there is a definite winner between the two, and I figured I would share my experience to help the next person who might be trying to decide between the two.Note, there are reviews out already especially of the DE-5000, and this is not intended to be an in-depth review. More a high-level comparison of the two different meters, that will hopefully help someone else make a decision between the two.User interfaceUsing the two meters is a significantly different experience. The ET432 has a color screen and can use dedicated arrow keys to be able to select parameters and make changes whereas the DE-5000 only has dedicated keys. The biggest difference I noted though was that the ET432 allows for quickly cycling through the secondary parameters while the meter is in auto mode. This was a nice timesaver if measuring different types of components. The screen on the ET432 was nice and clear and easily readable. The screen on the DE-5000 on the other hand seemed to have poor contrast, and the backlight was mediocre at best. One other thing that I liked about the ET432 was the adjustable power off timeout. It could be adjusted through the setup menu, and could even be turned off.Winner - ET432 for the color screen and the quicker navigation of the different features.FeaturesBoth meters have similar features, with both supporting 100Hz to 100Khz measurement. They both can measure inductance, capacitance, and resistance, and they both support DC resistance measurements. The East tester also adds the ability to apply a DC bias, selectable level and has a dedicated electrolytic capacitor mode. This electrolytic capacitor mode automatically applies a DC bias, to ensure that the sine wave does not go negative while measuring the capacitor.Winner - ET 432, for the selectable level and DC bias.Included accessoriesBoth meters can be ordered with different accessories for different prices, but there is a significant difference in the accessories. An interesting difference in the basic accessories though is that the ET432 included a shorting bar, whereas I could not find an option to recieve the shorting bar with a DE-5000.The ET432 can be ordered with true 4 wire Kelvin clips, whereas the DE-5000 clips are 4 wire to the clips, but then soldered together to standard alligator clips. This is easy to remedy, but will require purchasing separate Kelvin clips, and soldering the new clips in place of the alligator clips.The ET432 can be ordered with tweezers, but they are pretty cheap. They appear to be bare wire run to a bent tab, soldered together then covered with heat shrink. They appear to get the job done but are not nearly as nice as the molded plastic handled with a real PCB board that the DE-5000 tweezers come with.Winner - Tie. The ET432 has nicer clips, but the DE-5000 has nicer tweezers.Build QualityBoth meters feel substantial, and solid when holding. The ET432 has a silicone sleeve that will protect it from drops, whereas the DE-5000 does not have any type of protection. The sleeve is substantially thick but the fit is a bit loose, the tilting bale is floppy, and the meter has slots that the sleeve fits into, making the sleeve almost required for use. In fact, while performing my tests, the tilting bale was so floppy, that it came out of the sleeve causing the meter to fall over. The DE was more stable but feels very light and rocks when standing. I never had it fall over, but it did have a tendency to slide on my workbench if I was not careful pressing buttons. The buttons took a very light press to actuate, so in practice I was able to adapt to the light presses needed.I opened up both and internally they were neatly layed out, with no bodges. Both meters had what appeared to be leftover flux residue on the input jacks, but the rest of each PCB was clean. The DE-5000 solder joints all look nice, whereas the ET432 input clips had incomplete solder joints. Other than the input solder joints on the ET432, the rest of the soldering looks good.I included a photo of the inside of the ET432 for anyone interested.Winner - DE-5000 due to the incomplete solder joints inside the ET432, and the fact that the tilting bale came loose during my functional testing.ImplementationThe DE-5000 is well known to be an integrated chip solution, and when I researched the ET432 there was speculation that it was a similar implementation. The PCB said a very different story though. When I opened up the ET432 it was full of electronic switches and muxes. The ET432 appears that it is a more conventional implementation with discrete components compared to the integrated chipset of the DE-5000. One substantial difference is that the DE-5000 contains 6 range resistors covering 100Ohm to 1MOhm range, and the ET432 only contains 5 range resistors covering 100Ohm to 100KOhm. I suspect this missing range resistor proved to make a demonstrable difference in the measurement performance.Winner - Subjective, but the extra range resistor does give the DE-5000 ad advantage when measuring high resistance devices.MeasurementsThis is where the two meters started to substantially differ. The ET432 is a 40k count meter whereas the DE-5000 is only a 20K count meter. This better precision combined with the better specifications should make the ET432 a far more capable meter than the DE-5000. In practice this did not prove to be the case. To test out the two meters, I measured some capacitors and resistors.Here is a quick overview of the results. All measurements taken using 4 wire Kelvin clips, except for the measurements taken with a Fluke 189.As an ESR reference, I used a signal generator and my Fluke 189 to determine ESR following the instructions athttp://www.kerrywong.com/2015/11/23/esr-measurement-using-multimeter-and-function-generator/.47 uf polymer capacitorMeter Capacitance (120Hz) D(120Hz) ESR(100KHz)DE 49.45uF 0.026 28mOhmET 49.88uF 0.0296 42.30mOhmFluke 52.4uF ------- 28mOhmAfter taking these measurements, I was surprised that the ET432 was so far off measuring the ESR. To rule out fixturing, I re-tested by putting the resistor directly in the measurement slots of each meter. The readings on the DE did not substantially change, but the ET432 ESR dropped to a more expected 24.89mOhm. I then tried using the bananna jacks with the included alligator clips, and the ET432 then read 23.9mOhm for ESR. As it turns out, instead of testing the meter, I proved what we all already knew. Fixturing matter a LOT when performing measurements!AND I also proved that the included Kelvin clips look nice but are actually crap.20K 0.1% film resistorMeter DCR 100Hz 1KHz 100KhzDE 20.01KOhm 20.00kOhm 20.00KOhm 19.98KOhmET 19.991KOhm 20.004KOhm 20.005KOhm 19.659KOhmFluke 20.007KOhm ------ ------- -------These results also do not bode well for the ET432. The DE-5000 is accurate well within its specifications at all frequencies, but the ET432 is 1.75% out (Spec is 0.8%) measuring the resistor at 100KHz10M 0.5% carbon resistorMeter DCR 100Hz 1KHz 100KhzDE 10.080MOhm 9.996MOhm 9.998MOhm OLET 9.901MOhm 9.905MOhm 6.311MOhm 14.075KOhmFluke 10.008MOhm ------ ------- -------This tells a similar story to the 20K resistor. The DE-5000 exceeded its specifications in all ranges except for the 100KHz range. To be fair to the meter, the manual also indicates that there is no specification for the 20MOhm range at 100KHz, so this is documented behavior. The ET432 on the other hand, while within its specifications at DCR and 100HZ was measuring almost half the resistance at 1Khz, and orders of magnitude too low in the 100KHz range.The fact that the ET is so far off on the 10M resistor is interesting to me. The DE has a 1MOhm range resistor, but the ET432 only has a 100KOhm range resistor as its highest value. I wonder if the ET meter would have done better if it has a 1MOhm range resistor.After the reasonable testing, I figured I would have some fun and I attempted to measure the input impedance of my Brymen 789.BM789 input (6V DC range)Meter Capacitance (100Hz) Resistance (100Hz) Resistance (DCR)DE 68pF 10.97MOhm 11.119MOhmET 64pF 9.099mOhm 10.94MOhmFluke 200nF ----------- 11.120MOhmSince the Brymen specified the input capacitance as 75pF, I would say both LCR meters did an acceptable job measuring the input. The ET measured resistance low again, but within its specifications and the DE measured the resistance well within its specifications. The Fluke did not accurately measure the input capacitance, which shows why a proper LCR meter is needed if measuring complex impedance.In addition to the readings above, the DE-5000 readings were always consistently repeatable after performing the compensation routine. The ET432 on the other hand did not seem to have as consistent readings and would change every time the compensation routine was run. The DE-5000 readings were also extremely stable once the final reading was reached, whereas the ET432 readings had a tendency to vary 10's of counts constantly.Winner - DE-5000 due to the inaccuracy of the ET432 at 100KHz, and the questionable repeatability.ConclusionI really liked the ET432 meter. It has a great display and quick intuitive user interface and was great to use. I may have gotten a bad meter, but based on my testing unfortunately it's measurement capabilities at 100KHz don't live up to the specification sheet. Additionally, the Kelvin clips included with the ET432 look nice but seem to perform worse that the included two wire alligator clips. I have reached out to the seller of the ET432, and will update with their response. The DE-5000 on the other hand does not have quite as nice of a display, and the user interface is not as nice to use, but the measurements were all spot on with the expected values.Based on this quick test, the DE-5000 is a much more reliable and accurate meter than the ET432. The ET432 has great potential, but the measurements outside of its published specifications, makes it impossible to recommend.

content: Nice work, and why we have the DE-5000, it just works and gives the correct results!!Agree the TL-21 Alligator clips supplied with the DE-5000 don't seem like they would perform as well as the popular Kelvin clips with the separate BNCs, but they do and are actually better performers!! We had made up a set of typical Kelvin clips for the DE-5000 with a modified TL-21, but after some evaluations the Alligator clips proved more reliable, repeatable, and easier to use (shorter cables certainly helps with a handheld).We then took the modded TL-21 with the Kelvin clips and removed the clips, then attached a set of 4 BNC connectors/cables that can mate with the standard Bench LCR meter fixtures. This proved to be very useful indeed, and now we can utilize all the precision LCR meter fixtures available, including SMD fixtures, with the DE-5000. Here's link discussing such, see page 3.https://www.eevblog.com/forum/testgear/de-5000-lcr-tl-21-mod/msg4754858/#msg4754858We've done a considerable amount of testing with the DE-5000 compared to the lab grade bench Hioki IM3536 and Tonghui TH2830 LCR meters, and the DE-5000 has earned a spot up front on our test bench, and is the "Go To" resource for quick, reliable L & C measurements.Best,

content: Quote from: mawyatt on May 16, 2023, 02:52:44 amThanks!Based on my research, I knew that the DE-5000 was a good meter. I was tempted to just order it, and ignore the East Tester, but my curiosity got the better of me. Hopefully this post will be able to help the next person that is trying to decide between the two. I am honestly really bummed though because I really do like the ET432 user interface and screen so much better than the DE-5000. It has a lot of potential!I can't honestly say how well the alligator clips work on the DE-5000 because I immediately replaced them with the Kelvin clips mostly so I could have longer leads.The Kelvin clips I installed on the DE-5000 so far seem to work great and give identical measurements as inserting the components directly into the meter. If I was doing lab work, I would probably add the BNC connections the same as you did. This is my home toy though, so I doubt it will ever be used with a precision fixture.Hearing stories about comparing the DE-5000 to lab grade bench meters is impressive. It definitely says a lot about just how good that integrated chipset is!

The ET has the same open and close calibration as the DEIt does appear that they put some input protection, but it does not appear to be more than a PTC and some diodes.Since the Hantek has the same chipset as the DE, I suspect it would be very similar. I know there are other threads reviewing the Hantek.

content: Quote from: NoMoreMagicSmoke on May 16, 2023, 04:31:29 amActually the "Precision Fixture" doesn't cost much, both of the SMD fixture types we have were "roll the dice" cheap from AliExpress, under $100. We did rework the insides some for better repeatability, and on one we 3D printed a "V Groove" fixture that holds the smaller SMD DUT's better. Even for a hobby home use (we are retired but still do some EE consulting), this added BNC cable adapter & SMD fixture really expands the DE-5000 measurement capability and repeatability which is already quite good!!Edit: With the DE-5000 & SMD fixture you can do an Open Cal with the Fixture Plunger pried open to the expected SMD length DUT, this gives an accurate result of the DE-5000, BNC Cable and Fixture Capacitance. For the Short Cal we use 0 ohm SMD devices in 0603, 0805, 1206 and so on sizes, this gives a good representation for the total loop resistance in the DE-5000, BNC Cables and SMD Fixture.Best,

content: For the price the DE5000 is unbeatable, the ET4410 is "better" but cost much more (appx 300).Little bit surprising that the ET432 performs worse vs DE5000.Reading it´s manual, the part with the accuracy, makes you mad...Diagrams, formulars, tables, correction factors...But it would be interesting to find out why it´s getting partly out of it´s own specs*.Nevertheless, the ET433 is interesting because of the free adjustable testfrequencies.*)At the end the shown values are calculation results, so the "frontend" must be the cause.

content: Quote from: Martin72 on May 16, 2023, 10:02:18 pmCuriosity got the better of me again, and I decided to try to see if I could determine what might cause the 100KHz resistance measurement errors.I found that in the 100Khz range the output voltage drops from and expected 610mV at the lower frequencies to 440mV. If it's doing its calculations thinking the voltage is still 600mV that would certainly be a cause of error. The DE does not exhibit this behavior. The DE has is off for about a second when switching ranges, but then rapidly recovers to about 630mV.It appears (speculation on my part) like the ET is controlling the voltage open loop, and the DE has feedback that ensures the voltage is constant.

content: Quote from: Martin72 on May 16, 2023, 10:02:18 pmSo, I heard back from the seller, and they are insistent that the meter is operating normally. First, they tried to blame it on the resistor itself, then when I showed them the DE vs ET measurements, they said the difference is because the ET is a 5 digit, and the DE is only showing 4 digits.I did get them to agree to sending me out a replacement set of Kelvin clips, but they said they would provide tracking and I still have not received tracking information 3 days later.

The seller is listed as "East Tester Factory Store" That means the seller is directly the factory... Right??? Right???I measured the voltage with both a Fluke 189 as well as an oscilloscope. I am certain that my measurement affected the voltage some, but I listed it mostly to point out a difference between the DE (No voltage change) and the ET (drops demonstrably.The more I did into the ET, the more it confuses me. How on earth are they making a 40k count meter when the only DAQ on the meter is the 12 bit DAQ built into the CPU???

The vendor also confirmand that their testing showed that the ET432 is out of specification when measuring a 20K resistor at 100KHz (and gets worse as the resistance goes up). They said that the engineer was investigating, and they would let me know once they have a resolution.

content: Old-style "carbon composition" high-resistance resistors fall off dramatically in resistance with frequency: the talc grains mixed with the carbon grains to increase the resistivity "short out" the carbon capacitively at high frequencies.Resistors that have a helix cut into them to increase the resistive length will have a less dramatic effect due to the capacitance between "turns" of the helix.Resistors with a "bulk" structure are better, but it is difficult to achieve a high resistance value in a normal-size package.Many years ago, faced with this problem in TH resistors, I found "carbon ink" resistors from IRC to be the best at frequencies between 2 and 10 MHz, but I don't think they are still available.My requirement was to achieve the maximum equivalent parallel resistance, since the parallel capacitance was part of the tuned circuit, where the resistor was required for DC bias purposes.Some thick-film resistors (without helix) are similar.

content: Quote from: Def461 on June 26, 2023, 06:08:54 pmYou are having the same run around I got. I had to provide them with the exact part number of the resistors I was using, and a demo of a different meter measuring it correctly before they finally admitted they reproduced the issue themselves.

content: Below the accuracy graphs of my unit ET432.They were done using Vishay Ultra High Precision Z-Foil Resistors (0.005%) up to 100kohm and a calibrated 0.1% metal film resistor for 1Mohm.The instrument I have is well within the manufacturer's specifications almost everywhere. The only critical point, as observed by other users, is at 100kHz on the 1Mohm value where the accuracy is borderline (but still within spec...).Remember that for resistance values higher than approximately 10k, in order to minimize the error, the most appropriate equivalent representation to select is the parallel circuit.

content: Quote from: ExaLab on July 10, 2023, 08:55:07 pmJust to complete, the accuracy graph for a 10Mohm metal film resistor.As expected, excellent behavior up to 40kHz and -8% drop at 100kHz (but still within spec.).What to say more? The instrument is not very performing @ 100kHz for resistance values higher than 1Mohm.However, in my opinion it remains an excellent LCR analyzer!!More, the manufacturer provides a very complete user manual, full of information especially in relation to the accuracy of all the parameters measured by the instrument.This is another plus point that should not be underestimated...

content: If anyone is interested, I can share a useful synthesis of the most important aspects concerning the measurement accuracy of the ET432.In this, among many things, the user manual accuracy tables have been reformatted in such a way as to clearly highlight which are the measurement ranges within which the instrument exhibits its basic accuracy (i.e. 0.2%) and those where performance is no longer optimal.For quick consultation, they can be printed on two A5 format cards to be kept together with the instrument.

content: A Kerry Wong follow-up video to this showed that in 1833C the guard port is doing nothing. Have an identical model, tested it and indeed there's no signal coming out of guard no matter the measuring selections chosen.Wondering if somebody else is facing the same and if this is a firmware issue since the port appears to be connected internally.Regards.- CristianoQuote from: coromonadalix on May 16, 2023, 06:58:22 pm

content: In the DE5000, the four "high" and "low" terminals are generated and measured with respect to the "guard" terminal.In making external fixtures, I connect the coax shields and metal boxes to the guard terminal with a fifth wire.

content: Quote from: montecri on July 13, 2023, 07:43:14 pmcan some owners of this Hantek LCR meter check behavior of their devices?on my 1832c, when powered from battery the measurement signal interrupted every 20 seconds, right after each interruptions the readings jumping around 1-2%, but when device powered by USB external power supply this not happened - signal continues without interruptions.

content: As far as I read, Hantek is ok like DE 5000? Or am I wrong??Does anybody test and compare "PeakTech LCR/ESR meter, 100 Hz - 100 kHz, with USB, P 2170" with DE-5000??I have Hantek but I looked for this PeakTech, if it is better than DE-5000.
