Expencive

Strictly recommend for car drivers.

This is a great piece of kit

brilliant for the price, good for testing car batteries

---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.

Tenía la experiencia de de haber tenido uno, ahora que necesite uno pensé de inmediato, cumple con cada función que trae, para alguien que no es experto, puede aprender rápido.

Very happy with this piece of kit, as a DIY workshop mechanic It has what I needed without having to purchase an over priced meter for auto testing.

Sin funda para llevarlo y no se retroilumina la pantalla, pero de ahi el precio supongo,, los que si llevan esto pasan de los 120€.

Acheté pour mon père, celui ci a reçu des clés pour mécaniciens auto à la place du Multimètre.
