    • Just as it was described, easy to use
I liked it was user-friendly and purchase this item again save me a lot of time.

    • Great features but one issue for me
I like the multimeter. It does just about everything I need but it's hard for my old eyes to read the printing on the face of the device because it's slightly smugged and a difficult color for me to see.. I would still buy again.

    • Innova 3340a DMM: Lots of functions, volts and resistance accurate, tachometer needs improvement
I bought this because it is the only automotive meter I could find that offers a variety of RPM measurements: inductive pickup for spark plug wires; direct primary coil voltage monitoring for COP (coil on plug) systems; conventional old school tach measurements for distributor systems (for a wide range of cylinder counts); and DIS or waste spark systems. And of course dwell angle measurements. Most modern automotive meters have dispensed with all but the inductive pickup method but I like to have more options. I compared the Innova 3340a DC voltage readings for 1.5 v and 9 v batteries against a Fluke 87 V and measurements were within one or two-thousands of a volt. That is pretty good. When selecting DC volts the display shows 200-300 mV when no measurements are taken. This is due to internal noise from the autoranging circuitry. If I touch the probes together the display zeros out. As I stated, the DC volts measurements I took were very accurate. I compared resistance readings between the 3340a and Fluke for a variety of resistors from my electronics junk box and obtained excellent agreement between these instruments. Examples of 3340a vs. Fluke: 20.5 vs. 20.4 ohm; 27.0 vs. 27.4 ohm; 101.2 vs. 101.2 ohm; 147.5 vs. 147.6 ohm; 986 vs. 986 ohm; 51.1 vs. 51.1 Kohm; 730 vs. 729 Kohm. These resistance readings were off by only 0.1% on average. For my 3340a the accuracy is better on average than the range stated in the product literature. UPDATE Mar 10, 2020: I've had a chance to test the tachometer functions on a lawn mower that has a tach terminal (for the "RPM" function) and a high voltage spark plug wire for the inductive pickup clamp with the "CON" function. I compared the readings of the 3340a with those of a SunPro digital tach and a GTC505 ignition analyzer with a capacitive probe. With both the direct hookup "RPM" and inductive hookup "CON" functions, the average RPMs of the 3340a appeared to agree with the SunPro and GTC505 standards. However the 3340a gave very erratic and jumpy readings making it difficult to obtain an average RPM by eye. (With the "CON" function I had to halve the RPMs because a lawn mower delivers two sparks over the 4 strokes per cycle.) The "DIS" function gave confusing results. Maybe Innova needs to add some simple circuitry to average or smooth out the jumpy tach inputs. Maybe they need to add basic filtering circuitry to handle electrical noise from ignition systems. Either way the tach functions need some minor improvements to make the display more readable. This meter is a fine and accurate meter for basic electrical functions and is very well conceived. I hope that Innova does what they need to do to improve the tach functions and make it the great meter that it deserves to be, even if they have to increase the price a little. ... show more

    • It's Not a Fluke & It Isn't as Much as a Fluke
I read the reviews on this and decided it was good enough for my needs. I was specifically looking for something to use around the house and for automotive diagnosis within reason. Since this has a 10 Mega Ohm impedance it fit the bill at a reasonable cost (this allows for testing automotive computer systems without damaging them). As a note I am a retired auto tech that taught automotive electronics and driveability for over 20 years. I saw notes about the thermacouple and the units ability to read temp, it works well enough for my needs, even the much more expensive Flukes have issues reading temp depending on the situation. If I need greater accuracy in that department I would start by buying a different thermacouple, I do not believe the meter is the issue. The reason I gave it a 4 out of 5 is the leads. They really could have supplied better leads. For under $14 I purchased the KAIWEETS 51 inches Soft Silicone Electrician Test Leads Kit, it is very complete and has everything I need for this meter. I would recommend this meter for the home mechanic, I would stick with Fluke for professionals that need a meter on a daily basis. ... show more

    • Does the job!!
Great multimeter, had a fluke 88 and it took a fair amount of abuse and finally took a fall that it didn't survive after 20yrs.I am a Gm mechanic and on the tail end of career and didn't feel it necessary to put another 600.00 into a tool for a few more years....that being said this is perfect replacement, not as fast as fluke but gets the job done. Definitely recommend!!! ... show more

I bought this item new from Amazon in June 2016. I used it probably 12-15 times over the past year and 4 months. I turned it on to check voltage on a thermostat yesterday and the LCD screen was very faint unless I view it from an extreme angle. I figured, no big deal, it must be the batteries. Unfortunately, it does the exact same thing with new batteries. I called Innova and spoke with their tech support. They said it sounds like a defective screen and a flat rate repair on it is $89.99. I paid less than that for the unit new. I asked if they could repair at their expense and they said it's out of warranty (1 year), which is what I expected. I asked if this was a known problem and the tech said no. I am not the type of person that buys products that go defective near their warranty expiration date. I will give Innova full points for at least having a phone number and answering the call (I was on hold less than 5 minutes). But, being it's the only time I have purchased from this company, it's the only experience I have to decide if I will do business with them again. The tech's suggestion was to buy another one. I think I'll try another brand. My $19 multi-meter from Radio Shack still works after 15 years, so I guess I could use that. ... show more
