We have made a list of five best automotive multimeters. If you decide to choose either one of these, you won’t make a mistake. Every single one has a ton of additional features and useful functions. They are very easy to use and suitable for both professionals and beginners. People often think that the price determines quality.
With all of the functionality of a standard digital multimeter + exclusive HVAC modes, the Fluke 116 digital multimeter is specifically made for engineers who work in the HVAC (heating, ventilation and air conditioning) industries.Unlike other models in the Fluke 110 series, the Fluke 116 includes exclusive functions such as a built-in thermometer for measuring temperature and a microamp mode designed for testing flame sensors. It can also test all standard electrical parameters, including resistance, continuity, frequency, capacitance and voltage.The Fluke 116 is exactly what you’d expect from Fluke: rugged, reliable and highly accurate. It’s true RMS, so it’ll maintain its accuracy even when testing on irregular AC connections and built-in low input impedance ensures that ghost voltages don’t have an effect on any of your readings. When you’re working in darkened conditions, you can use the Fluke 116’s built-in large white LED backlit screen to see what you’re doing. If you’re needing to record results over a period of time, you can use the built-in maximum, minimum and average functions to gain a wide variety of readings

This is a pretty decent inexpensive multimeter. I put it in my tool bag that I carry around with me to different sites, so that I could leave my more expensive multimeter on my work bench at home, where I do most of my work, and not have to worry about losing the Fluke or forgetting to bring it with me. For what I do (I’m a theatre technician) this multimeter works well for most purposes. I also thought the battery test feature would be un-necessairy, but it so happens that there is a large bucket of battery of unknown condition in one of the shops that I work in, and the lights made it really simple for me to hand this multimeter to an assistant and say “If the light is green keep the battery, otherwise, recycle it.”.
My one minor complaint is that the tips on the two probes that come with this multimeter are not super “sensitive”. I don’t know if that is the right word, but sometimes it seems like you have to touch the very tip of the probe to the contact you want it to have. This is good for testing precise things, but sometimes is disadvantageous if you at trying to test power connectors.
The INNOVA 3320 is a Auto-Ranging Multimeter designed to safely and accurately troubleshoot a variety of automotive and household electrical problems. It’s auto-ranging scales eliminate the need to dial in the correct range when making electronic measurements. The 10 MegOhm input is safe for automotive and household uses (i.e., household outlets, fuses, wiring, general-purpose batteries, vehicle battery and charging system, automotive circuits and more). The color-coded LEDs allow you to quickly check household batteries (green = good, yellow = weak and red = replace). Includes attachable test leads, holders and stand for hands free use and features protective rubber corner guards for drop protection. The INNOVA 3320 has a single setting resistance function for AC and DC voltage.
