Featuring auto-ranging scales, a large digital display with color-coded LEDs for quick battery status checks, and a high 10 MegOhm input impedance to protect vehicle ECUs, it combines precision, safety, and convenience in a compact, durable design. ## Description The INNOVA 3320 is an Auto-Ranging Multimeter designed to accurately troubleshoot a variety of automotive and household electrical problems. The 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. ## Features - UL certified product designed to safely and accurately troubleshoot a variety of automotive and household electrical problems - Auto-ranging scales automatically selects correct measurement range and eliminate the need to dial in the correct range when making electronic measurements - Features large digital display and color coded LED's to easily check the charge status of batteries - Single-setting resistance function for AC and DC voltage - 10 MegOhm input impedance; safe for electrical and automotive use; prevents damage to the vehicle’s ECU ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000EVYGZA | | Best Sellers Rank | #36,074 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #54 in Multi Testers | | Brand Name | Innova | | Color | Red & Black | | Compatible Devices | Automotive electrical components, household electrical components, batteries, solar panels, fuses, wiring, and other electrical circuits | | Customer Reviews | 4.5 4.5 out of 5 stars (7,558) | | Global Trade Identification Number | 00042173033201 | | Included Components | Auto-Ranging DMM(10MegOhm)/UL | | Item Dimensions | 2 x 10 x 5 inches | | Item Type Name | Multimeters & Analyzers | | Item Weight | 0.5 Pounds | | Manufacturer | INNOVA | | Measurement Type | Multimeter | | Model | 3320 | | Part Number | 3320 | | Power Source | Battery Powered | | Specification Met | UL | | Style Name | 3320 | | UPC | 001910645411 666669796113 798804832315 521227772056 077344764820 031112449586 071040126067 421730332016 069060059328 706949169272 601000676778 050005685832 604945280994 522536500354 971477621855 042173033201 | | Unit Count | 1.0 Count | | Warranty Description | 1 year limited | ## Product Details - **Brand:** Innova - **Color:** Red & Black - **Item Weight:** 0.5 Pounds - **Power Source:** Battery Powered - **Style:** 3320 ## Images ![3320 Auto-Ranging Digital Multimeter, Red & Black - Image 1](https://m.media-amazon.com/images/I/81w4giNVNoL.jpg) ## Questions & Answers **Q: I am searching for current leak in a boat (12v battery). Will this dial down to low enough amps to diagnose? Thanks.** A: Yes, the Innova is great for finding parasitic leaks in boats and cars. Turn everything off..... EVERYTHING and then disconnect the negative battery cable. Insert the meter in series with the neg bat terminal and the end of the cable. If there is a current leak it will show on the meter when it is set on the AMPS function. Becareful that you don't turn anything on when the meter is connected because the AMP mode is not fused. If a current reading shows on the meter start pulling fuses and disconnecting devices until the reading drops to zero therefore isolating the problem **Q: Can I use this meter to test for bad circuit breakers at electrical panel or electrical outlets at home? I'm newbie; want learn how to use. Thank u!** A: I would advise against it. This is only a CAT 2 rated meter. That means the internal safety features are not sufficient to handle the higher potential voltage and energy that could come about at a meter panel. http://www.ni.com/white-paper/5019/enYou really want a CAT 3 meter if you want to measure any live breaker panels.If you are going to test for bad circuit breakers that are disconnected from the live wiring then you could use this meter to check for continuity and the like. Do not use this meter on anything more powerful than a wall outlet. CAT 3 meters are available for not much more money. **Q: What's the lowest ohm reading it is capable of? 0.01? 0.1? 1.0?** A: It may have 3 digits but it can not accurately measure milli-ohms, nor can any other meter that is not using a 4 wire probe setup and one that costs at least several hundred dollars. There is so much involved in getting milli-ohm accuracy I could write for hours, for example just the pressure and angle of your probes, the proximity of the wires to themselves, other metal object, flex of the probes, the fitting of probes in the meter, and thats just 1/10th of probe issues, then take in account of the power supply related issues, pcb design issues a to d conversions and no way can a 18$ meter give accurate or even relative accurate milli-ohm readings. It is just a common marketing ploy. **Q: Does this unit have CONTINUITY testing to determine which are the traveler wires in a 3-way switch outlet? It has a HORN icon which looks like it would beep if continuity is foun (e.g. the travelers going from one to the next switch box) but I don't see CONTINUITY testing in the features list. Thanks!** A: I don't know enough about residential wiring to answer your question, but yes, the HORN icon is what you select for continuity testing, and it beeps when the circuit is complete. ## Frequently Bought Together - INNOVA 3320 Auto-Ranging Digital Multimeter, Red & Black - Aenllosi Hard Case Replacement for Fits INNOVA 3320/3340 Auto-Ranging Digital Multimeter (red) - KAIWEETS Soft Silicone Electrician Test Leads Kit CAT III 1000V & CAT IV 600V with Alligator Clips and Needle Probe for Fluke/AstroAI/INNOVA Multimeter Electronic Clamp Meter 9PCS --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1139249-3320-auto-ranging-digital-multimeter-red-and-black](https://www.desertcart.tn/products/1139249-3320-auto-ranging-digital-multimeter-red-and-black) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-04*
