🔧 Innova 3340 Pro Auto Digital Multimeter Review

A good multimeter with all necessary functions. Two minor drawbacks, both related to response time: Firstly, the continuity tester has a short delay (0.25-0.50s) before it beeps - this can be annoying when trying to analyze a device with a lot of cables, or when it is difficult to maintain contact for a long time, leading to many false negatives. The other is that autoranging takes forever to scale down low voltage/current/resistance cables, on the order of two seconds in most cases. These…

I like the meter and it seems to be working fine, but the battery charge test LEDs are not working on my meter. I won't be returning it because of this, but it was a little disappointing. UPDATE 2/28/2018 I decided to send the meter in for a replacement after discovering another issue with it. It stopped measuring current and didn't close the circuit when current was measured. Received a replacement from Revain very quickly, so HI for this pre-delivery. The new meter failed just like the…

I read the reviews on it and thought it was good enough for my needs. I was specifically looking for something within reasonable limits for home use and for vehicle diagnostics. Since it has an impedance of 10MΩ, it's spot on for a reasonable price (allows you to test vehicle computer systems without damaging them). As a side note, I'm a retired automotive technician who has been teaching automotive electronics and driving controls for over 20 years. I've seen references to the thermocouple and

First, it's smaller than expected. Good size screen. The handle is a bit small, but that's okay. The auto range feature is really useful and works well. The continuity test beep is too quiet to be useful when there is background noise, e.g. B. when the engine or fan motor is running. The plastic tabs on the case are ridiculously bad. Don't expect the probes to stay in there as shown in the picture, not even remotely. One final note: this is an Equus sub-brand product. For those who haven't had…

I purchased this item new from Revain in June 2016. I've used it probably 12-15 times in the last year and 4 months. I turned it on yesterday to check the voltage on the thermostat and the LCD was very dim unless I looked at it from an extreme angle. I thought, it's okay, it must be the batteries. Unfortunately, this also happens with new batteries. I called Innova and spoke to their tech support. They said it looks like a faulty screen and the repair fee is $89.99. I paid less than for a new…

The only good thing about this multimeter is the 2 day prime shipping. At my age I saw everything. The two most troubling issues are receiving a new item that is either dead or broken. My experience with Innova was getting a new BROKEN gauge. So instead of testing circuits, I'm forced to spend more valuable time returning this crappy meter and writing a review that will hopefully warn others to choose another brand. When a test device leaves the factory uninspected, or with such a shoddy…

spark plug wires; direct primary voltage regulation for COP (Coil on Plug) systems; traditional old-school tachometer readings for distribution systems (for a wide range of cylinder numbers); and DIS or depleted spark systems. And of course the measurement of the departure angle. Most modern car counters don't use all measurement methods except inductive, but I'd like to have more options. Volt. It is very good. If DC voltage is selected, the display will show 200-300 mV when no measurement is…
