De-5000 Handheld LCR Meter (Discontinued Replaced By De-6000)

Not sure which unit this is since Amazon add says the 5000 was discontinued but still says 5000 on the case. No English instructions for the price, false advertising(see below) - 3 stars.Seller advised me that the 5000 has not been replaced, add on Amazon was incorrect.

The meter works well. I was surprised there was no leads with it.

Please be careful with these meters, if I could give no stars I would, they have good reviews but the 2 I ordered had a serious flaw. The first meter I purchased was used but in good condition, I opened up the battery compartment, put in a fresh 9 volt battery and the battery heated up instantly, the battery compartment pins have a 9 volt cradle that only allows the battery to go in one way, as soon as I put the battery in, the battery itself immediately heated up. I sent it back, my money was refunded, so I decided to purchase a second DE-5000 because I thought maybe I had received a defective one. The 2nd one I purchased was brand new, this too did the very same thing, they even included a battery and the battery heats up so fast that I had a hard time removing it from it's cradle. I tested the battery pins and found that they are shorted in both cases. If I were to close the battery compartment, well lets just say the meter might have been a charred mess or my home may not be have been here anymore, extremely disappointed. Buyer Beware!!!

A great LCR meter, but the product is incomplete! The picture is deceiving.

The DE-5000 LCR meter is very nice, accurate and flexible, easy to use and low cost. It has great capability for the price: 4 terminal (Kelvin) connections measure down to about .001 ohms, making it great for low value resistors and wire measurements. 100KHz max frequency is good for low value L's and C's.There are reviews on-line, and Dave Jones EEVBLog has a teardown. He shows that all the analog signal processing is done on just one IC plus a some discrete components. Rugged construction and nice design.The specs are about +/- 0.3% (another reviewer incorrectly calls it 0.03%. I wish!) but the measured accuracy on precision resistors I measured was close to 0.1%.The vendor shipped quickly from Japan and included a polite thank-you note and a couple of origamis. My wife really appreciates these.For an English manual see www.ietlabs.com/pdf/Manuals/DE_5000_im.pdfThis version ($129) comes with no leads, just the slot for leaded components. I ordered the tweezer (TL-22) and alligator clip (TL-21) separately. It is probably cheaper to order them with the meter than separately. These are 4 terminal probes within about 1" of the DUT, which are within a few milli-ohms, but they are not true 4 terminal measurements. Very handy though. I prefer the large alligator clip leads used on other LCR meters since they provide true 4-terrminal connection at the DUT, and even allow tiny SMT measurements. I will modify the TL21 to wire in a set of these large clips that I bought separately. There are instructions on how to do this on-line.

WARNING: I received this meter without a case, which is something I specifically wanted and expected. When I complained the seller told me the case would cost an additional $15. At least the photo no longer shows a case. I'm leaving this review to note this issue as other reviews state the case is included.

Edited to add: Beware of units sold by vendors other than IET or Amazon, as a similar unit exists which is an older instrument branded "Der EE." This is not the same instrument as the IET-branded one. IET Labs worked with an OEM to created their version, using their design input and internal software. I would suspect that the older unit might not meet the specifications and repeatability of the IET unit. Caveat emptor!After leaving a career in metrology, standards and calibration lasting over 30 years, I thought I wouldn't miss it. As it turns out, I had collected lots of my own equipment over the years and have been rounding out some of the missing elements I was so accustomed to having access to in an accredited, broad-capability lab environment. I've been needing a reliable LCR meter to replace my antique HP which needs unobtanium part galore and didn't want to take on yet another needy antique. Looking around at the various handheld portables I find so many of them with limited capabilities or dismal specs, with reliability a huge unknown. Agilent and B&K Precision had a couple models that piqued my interest, but I wasn't sold. I had found the OEM version of this meter before and didn't give it any thought, it seemed a huge unknown with little published information. I ran across this IET-branded version and had to take a look. I am very familiar with IET, Quad-Tech, ESI and old & new General Radio/GenRad equipment as many of these brands made up the core of my working and primary resistance/impedance (L-C) standards and more. IET is the umbrella company of all these brands these days and seeing their name applied to this particular instrument made me believe there was something more to it. I read the rather impressive specs and did some research with the DE-5000 held against other units I was considering. I came away completely impressed with the unit on paper, and figured if this meter had IET's considerable backing and support, it had to be a top contender. Weighing all the available options I had, I pulled the trigger and ordered one. I'm very happy I did.The unit arrived securely packed and undamaged. I was pleased to find the kit box of a higher quality that I expected, the OEM version apparently not shipping with the box. Inside was a tidy, well laid-out package consisting of the DE-5000 itself, the alligator clip test adapter TL-21, TL-23 guard/ground lead, the DE-5000-AC 120-240VAC adapter (I had expected this to be optional) and a genuine Duracell 9V alkaline battery, plus the well-written user's manual tucked in the kit box lid. The unit itself is solid, substantial and extremely well made. There is no soft-shell holster or rubber overmold, and in my opinion, none is needed given the typical environment the meter will be used in. A cursory internal inspection shows me the unit is very overbuilt and rugged. It's far from fragile! Excellent "out of box experience."I put the DE-5000 through its paces on my collection of "check standards", a set of measured, high-precision resistors, capacitors and inductors I keep as my personal standards lab to verify my own gear. The DE-5000 measured all of these well within its already impressive specs. The TL-21 adapter actually brings a true Kelvin 4-terminal guarded (shielded) measurement connection right to the alligator clips. This makes reading low-to-milliohm resistance far more repeatable and accurate than the typical pair of test leads. Very unexpected to find the four-wire model applying to the two banana jacks, which are internally split and make a separate source/sense connection to each side of an inserted banana plug. Impressive! This calls for the use of high quality test leads for two-wire measurements. Using either the included test fixture/leads or other test leads, a simple automated open/short calibration process can be made using a single key to offset stray L/C/R effects and ensure accurate measurements. The included guard terminal and lead ensure that low L/C and high resistance readings can be taken by enclosing the DUT in a shield, or using the device frame or shell like those found with IF cans or variable capacitors, without introducing errors due to stray EMF and the like. The unit also has slots that accept wire- or tab-leaded components right at the front panel, perfect for small component testing. Just plug the leads in. As a bonus, these clips apply a Kelvin 4-terminal measurement directly to the leads, as the lead opens the clips, each half of the clip is a separate source and sense terminal. This makes for accurate and repeatable measurements every time.The breadth of measured parameters the meter presents are practically perfect. Along with the direct autoranging values of resistance in ohms, capacitance in farads and inductance in henries, the unit measures selectable series and parallel inductance and capacitance for each component type, ESR in series and parallel, Q, dissipation factor and phase angle. Five test frequencies are available (100Hz, 120Hz (think AC line filtering here), 1kHz, 10kHz and 100kHz) making multi-ranged measurements of individual components possible. I like to design & build amplifiers and crossover networks in addition to making repairs to them plus lots of other electronic gear, the DE-5000 makes selecting and matching passives very easy already. A "Sort" function is included to allow the user to enter a specific component value then choose from a number of industry standard tolerances, then test a batch of components with the DE-5000 indicating when a DUT falls outside the spec range. This is a fantastic add-on for those needing to match component tolerances for precision, or just make sure an unknown pile of parts fall within acceptable limits. Wonderful addition for a hand-held meter.The dual display is easy to read, has blue backlighting and has separate 20,000 and 2,000 count simultaneous readouts of primary and secondary parameters. There is also an analog bar graph provided as well, great for testing variable devices or sensing intermittents. You can let the DE-5000 automatically select the appropriate set of readings automatically regardless of what device you connect, or manually select the main function as well as the secondary reading as you need. With a capacitor connected, you can select the inductance measurement to read internal series inductance, for example. Since the meter uses either AC or DC excitation to measure resistance, you can take a typical DC resistance reading and compare it to the reading given at different test frequencies. This is fantastic to find out if a component becomes reactive when in circuit. A handheld or bench DMM can't do this. Useful to find out if a wirewound resistor is appropriate for a particular design or for replacement. If it's reactive, you can measure its inductance or capacitance as well. For critical testing, Q, D and ESR parameters are available. Find out if that replacement electrolytic cap you are considering for a switching supply is adequate. Create high-quality filters and crossovers. For the engineer, technician or serious electronics hobbyist, this unit is a practical must.My list of "cons" is short. I wished the TL-21 leads were a tad longer, there are some components (large, small-value HV capacitors for one) that I'd like to measure using the shielded leads. The TL-22 SMD tweezers for me are a must, and those, along with the other available option, the DE-5000-DTK USB data transfer interface and software are not sold on Amazon by IET and these are worthy, must-have (especially the SMD tweezers) additions. These, along with the standard TL-21 should be easily available. I'd like to have a spare TL-21 adapter to modify with longer shielded two conductor cable to make the aforementioned test connection for bigger components. IET can make either a "deluxe" version of the kit available here and/or provide an easy link for purchasing the accessories to round out an already impressive setup.To sum it up, I am impressed with this unit and its specs and capabilities. Having it backed by a company at the forefront of impedance measuring technology made the purchasing decision swift and easy.Edited to add: Thanks to the attention of Mr. Sheena from IET, I now have the TL22 SMD tweezers to complete my LCR test kit. The tweezers are well constructed and have excellent shielding all the way to the tips. As long as the tweezers are gripped behind the molded-in ridges near the tips, there is absolutely no added stray capacitance or other artifacts added to the readings even on the lowest cap ranges. I was able to test the values of a small pile of unknown value SMD resistors and caps without chasing them around with probes all over the bench or launching them across the room by accident. Anyone considering this meter and plans on doing any SMD or fine-pitch leaded component testing or troubleshooting should order up these SMD tweezers to complete the set.
