    • Terrible test leads on a very, VERY useful device.
This is a very good ESR tester that's been a welcome addition to my tool set. It's able to read ESR values in-circuit (no desoldering) and does really well detecting the proper capacitance values in automatic mode. The one criticism I'd offer for this device is that the supplied test leads are simply awful. They have alligator clips on them which are too coarse/large for most capacitors, and are completely useless for anything surface-mounted. In the end, I (as have others) replaced them with a set of short Kelvin clip leads, which are dramatically better and easier to work with. The leads have to be short or the meter won't zero properly, so buyer beware when getting replacements. Now that I have this device (and some decent leads), I'm easily able to determine which capacitors I need to replace in a circuit. ... show more

    • Pretty inexpensive, easy to use, accurate
This meter does exactly what it says - gives accurate ESR measurements, which greatly speeds up troubleshooting. The display is clear and easy to read. The chart on the front makes it convenient to look up what might be bordering in a cap that it says should be OK. The leads are a little short and I really wish they had included pinpoints as an alternate to the alligator clips, but I've made a workaround. Instructions say to zero between each measurement, which is a bit annoying, but not killer considering the cost. ... show more

    • This is a great tool for troubleshooting and saves me a lot of ...
I do electronics repair as a second job. This is a great tool for troubleshooting and saves me a lot of time. Bad capacitors are a frequent problem but they are difficult to test and I don't have the time to just replace every capacitor I run across on finicky equipment. PROs: Tests capacitors better than a multimeter without having to desolder them. Posts the results in plain English as well as the numeric readings. It's reliable. I have tested quite a few capacitors so far and the results so far are accurate and repeatable. It's inexpensive. I shopped around for a quality ESR and found that units typically cost more than this, have to ship from China or Russia, and frequently don't have as many features. CONSs: The battery door is difficult to get to. The stand is in the way. It's a minor hassle. I plan to just remove the stand entirely as I do not use it. It's not extremely precise, particularly on small capacitors. Caps below a certain point you have to look up on a table (which is handily printed on the unit). The numbers can vary a little but not enough to make a difference for what I'm testing. All I want to know is the answer to one question: "Is this a good cap?" It's precise enough to be accurate in answering this question and that is all I care about. ... show more

    • MESR-100 V2 Auto Ranging ESR Meter
I have many pieces of electronics that stopped working. Sound Bar, Electronic Whoopers, Sirens used in security protection systems plus a number of others. I don't have the time to spend diagnosing their problems because it is much simpler and faster to just go out and buy another one. One day while watching a You Tube video on electronics repairing for the non-professional, the host was demonstrating the use of this Signstek MESR-100 Ver2 ESR Meter with in-circuit testing. He stated that quite often that electronic equipment fails or failed because electrolytic capacitors were the culprit and this meter can check each capacitor in-circuit - which means I wouldn't have to remove each one to check it. Wow, my first impression was now I can repair the above quickly and save money in the process. Well, I didn't find (not one) failing or failed capacitor. OK, I must admit the cables are far to SHORT in length. I was dragging the meter all over the circuit boards attempting to check each capacitor. Each time I would finally make contact with (cable probes to a capacitor) the short cables turned the meter upside down or on its side to prevent me from seeing the display which would define information I need to determine if the capacitor was good or bad. This occurred too many times at which I promptly put the meter and cables back in the box and put it away. The cables make testing electrolytic capacitors a "NIGHTMARE" in circuit. Testing out of circuit is just fine and the meter tested every good electrolytic capacitor I had correctly. So, if the cables were longer this meter would probably warrant a five. Again, the meter appears to be a "near professional instrument" except for the cables which defeats the whole purpose of using it... in-circuit. Also, I believe the instructions have a statement to not substitute the cables supplied with longer ones. I am hoping either the manufacturer or a professional electronic technician will offer a solution for longer cables that would make this meter an excellent tool for diagnosing bad electrolytic capacitors in-circuit. ... show more

    • No more desoldering pointless capacitors that are actually fine!
This device has truly simplified the task of testing capacitors that are part of a circuit. It's the go-to solution if you don't want to go through the hassle of desoldering components just to perform a basic capacitor check. The auto-ranging feature is a lifesaver, making it incredibly easy to measure the Equivalent Series Resistance (ESR) and inductance (LCR) of capacitors while they're still soldered in. This is a game-changer for troubleshooting circuits and identifying faulty capacitors quickly and efficiently. Gone are the days of traditional, time-consuming desoldering and testing methods. The Signstek offers precision and convenience in one package, making it an invaluable tool for electronics enthusiasts and professionals. It has truly revolutionized the way we diagnose and maintain circuits, sparing us from the painstaking desoldering process. If you work with electronics and need to test capacitors in-circuit, this meter is a game-changer. ... show more
