Innova3320 Auto-Ranging Digital Multimeter, Red & Black

---10-23-2017 EDIT---I still have all 3 of my Innova 3320 multimeters, and they are still working great. Each one gets used a couple times a month on average, so they have more than paid for themselves over what has now been 6+ years of ownership. I also haven't felt a need to upgrade them in that time, so these 3 meters along with a 4th multimeter (that has a clamp style ammeter that I need occasionally) are all I own right now.There is a small quirk I have noticed with this meter, so I figured I would mention it in case anyone else has the same issue. Sometimes one of my meters will start giving a reading that is a bit erratic, almost like it's having a hard time knowing what it's supposed to do. Alternately, the autoranging feature will sometimes also become a bit sluggish in coming up with a final result to display. I mainly notice it when I'm working in DCV mode, and the issue pops up now and then on all 3 of my meters. Whenever one of my meters begins having this issue, a quick full rotation of the mode selection dial back and forth 5-6 times fixes the problem right up. I'm guessing there must be a little bit of dirt working down onto the sliding dial contacts (located directly underneath the mode selection dial) causing a poor electrical connection there over time. The dirt is probably getting in via the small gap around the dial itself. That dirt/residue is being scraped off by the sliding contacts when the dial is rotated back and forth a few times so that's why everything starts working perfectly again.Another thing I thought I would mention is that for the last couple years I have been using Eneloop rechargeable AA batteries in all 3 of my meters instead of regular disposable alkaline batteries. My meters all run perfectly on the Eneloops even though rechargeable AA batteries only put out 1.2vdc instead of 1.5vdc.---END OF EDIT---This is a great meter as long as you are getting it for the right tasks. The auto ranging feature works great as long as you are measuring something of a decent value whether it be resistance, voltage, etc. This is not the meter you would want for doing sensitive electronics, fine adjustments of electrical components, computer work, etc. This meter will not be accurate enough and consistent enough to be of much use for those types of applications. This meter is absolutely amazing for its price when it comes to doing (120vac) home electrical, automotive (12vdc) electrical troubleshooting, furnace troubleshooting (24vac), solar installation testing and troubleshooting (12-48vdc), etc. For electrical maintenance and installation tasks I almost exclusively use continuity, voltage, and resistance measurements to look for broken circuits, check for voltage loss across terminals due to corrosion, verify correct wiring after a new installation, etc. This meter also works great for testing automotive sensors for proper function. Most automotive sensors have resistance levels in the 400 to 700 ohm range when operating properly and this meter measures levels like that very consistently and accurately.Where this meter does falter a little is when you need to measure a very low resistance level or a very high level of resistance accurately. The auto ranging feature gets a little confused or slow, and is not good at giving the same result if the same test is repeated several times.The reason I am giving this meter 5 stars is because the issues with this meter are really not issues to me, because the situations that cause those issues can usually be worked around and 99% of the things I use this meter for work accurately and rapidly. I have used many high quality fluke meters and they work great in all situations, but they are also a lot more expensive. I will gladly give up 1% usability for a meter that is one fifth the price. I have also used meters that are cheaper than fluke meters and are still accurate in all situations, but they require you to set the range for every test done which adds time to everything and if you are wrong you can blow fuses, etc. This meter is fast, because I just turn the dial to the right mode, put the leads on and get a result I can use and I can move on.Another really nice feature I have never seen on another meter is the battery tester. It is great for rapidly testing to see if a spare battery you find in a drawer is a new one that became separated from its' package, or if it is a dead one that got lost on the way to the recycling bin.This meter is also nice because if you accidentally damage it or lose it you are not out much money. This meter works so perfectly for the tasks I need it for that I have bought 3 of them just in case they stop selling them, because there are no other meters I like as much as this one that cost less than $75. Then I am able to keep one in the car at all times for emergencies, one in the garage for working on cars, and one inside the home that stays nice and clean for home related tasks.

I recently purchased the Innova 3320 Digital Multimeter, and I couldn't be more satisfied with my decision. This multimeter boasts an impressive range of functionality, making it an essential tool for both novice and experienced DIY enthusiasts. The ability to measure voltage, current, and resistance with precision is a game-changer for my home projects.One standout feature is the bright, easy-to-read display. The backlit screen is especially useful when working in dimly lit areas, allowing me to take accurate readings without straining my eyes. I also appreciate the durable design; it feels robust and well-made, which gives me confidence that it will withstand the occasional drop or bump in my toolbox.In terms of performance, the Innova 3320 delivers reliable results consistently. I’ve used it for various tasks, from automotive diagnostics to basic electrical work, and it has exceeded my expectations every time. Overall, I would highly recommend the Innova 3320 Digital Multimeter to anyone in need of a dependable, user-friendly tool. It definitely deserves its five-star rating!

It works well and as expected with one flaw. The continuity tester (beeps when there is a complete circuit) has a delay of about a 1/2 second. In other words, if you touch the two probes together, you would expect it to beep instantly. It does not. It beeps after a 1/2 second. If I'm testing a project or circuit for a short, testing if a solder joint is solid, I need it to beep the instant that the probes touch the test points.One other issue that I have with it, is that it has a battery tester function. 4 pre-set voltages (1.5, 6, 9 and 12). Gives you a green yellow or red light depending on the battery's charge. Fine, except what about all of the new batteries that we use these days? NiMH, NiCD, LiPO, LiFE, etc. Each with it's own unique voltage range. I do a lot of DIY that involves batteries, also R/C modeling that uses a variety of battery technologies. The 4 pre-set voltages this meter comes set to are basically worthless to me. I tested a charged LiPO in both the 1.5v and 6v ranges, each showed an error. Sure, I can (and do) just use the DC tester but it seems a waste to have included this feature.Otherwise, it is well made, the silkscreened labels on the front are solid and easy to read. Display has huge characters also easy to read, though no back light. Built in bumper pads are tough.It has an elastic loop on the back, I assume so that you can attach it to something to hold it up so you can use both hands and read the display. Elastic material is pretty cheap and will not last (it will stretch and fail like the waistband on an old pair of underwear), but it should be easily replaced with a quality thin piece of bungee cord.Good price/ value, but not a pro or pro-sumer piece of gear.
