Innova 3320 Multimeter Complete Review

With its low price and auto-ranging digital multimeter, the INNOVA 3320 is a great first device for hobbyists. This meter can do most things that expensive brands are capable of (to some degree) without breaking your bank account. It also has an excellent battery test feature which means you won’t need to worry about losing power when checking over car electrical systems or other vehicles in campers stocked with gas lanterns.

A new updated model name “Innova 33200” was announced on their website.

When it comes to durability, the Innova 3320 is hard not to beat. The large digital display offers crystal-clear information and features an impressive battery tester that checks voltage as well! There are three LED lights in front of the multimeter which represent different levels so you know what yours looks like at all times – even while under load from a few small jobs around your house or office building (let alone heavy duty tasks). If these aren’t enough reasons for why this tool might be just right…there’s also its kickstand feature!”

Though it struggles on power circuits, the energizer multimeter is a great little meter for troubleshooting car wiring and general electrical issues around your home. In short – this product will get you out of trouble.

In-detail Review of the INNOVA 3320

INNOVA 3320 Auto-Ranging Digital Multimeter

Reasons To Buy

Cheap in Price

Large in Size, clear display

Auto ranging Multimeter – good feature for the cost

Accurate enough for small jobs

Handy battery test function

Battery life indicator

Fold-out kickstand

Elastic cord wrist strap

Long, sheathed probe leads

Reasons To Avoid

Auto ranging quite sluggish

Low AC amperage range

No capacitance range

With its sleek and stylish design, the INNOVA 3320 is perfect for any home workshop. This handy measuring tool can measure most electrical ranges from volts up to 600V as well as millivolts or amps; it also has a beeper if you’re looking at testing resistance between two points that have different values (like continuity). The best part? coloured LEDs so there won’t ever again need confusion when checking something important.

The best part about this device is its versatility. You can use it both for professional readings during serious projects or simply as a DIY enthusiast checking the batteries around your household, with plenty of features to tackle any analysis regarding capacitance frequency voltage current etc…

The auto range on this tester is a great addition, as it automatically works out the correct distance for any given test input and can handle all settings with ease. The only drawback? You have to manually select DC or AC ranges but other than that there are no problems.

The LCD screen on this meter is very easy to read, with large numbers that can be seen even from a distance. The main drawback of it being only accurate up to 200ma but you are able to test DC circuits which have 10A ability as well at 15 minute intervals if their amperage isn’t too high so they don’t cause any fires or electrical shorts in your house.

The overall input impedance of this meter is 10MΩ, which should have no detrimental effect when measuring resistance in a circuit. There aren’t any capacitance ranges either but it can measure up to 20m ohm on the low end for precision work or high frequency testing needs that require super sense accuracy.

Battery Test Function

This is a really great feature of the 3320. It has five LEDs that tell you exactly how much power is left in each battery, and it also provides an indication for when charging or using USB devices like smartphones.

The LEDS are appropriately color-coded:

GREEN = good

YELLOW = weak

RED = replace

If you don’t see any lights when your battery is low, this could be an indication that it’s time for a new one.

If neither LED shines brightly then chances are there will not only be no power but also very little left in their stores.

When checking the condition of your batteries, it is important to put them under load. The Equus multimeter does just this by applying 10mA into each battery until its reading becomes more accurate and reliable than what you would get without using this technique

A lot has changed in my world since I first started working as an electrician years ago but one thing that hasn’t really evolved much at all are our tools- which can sometimes seem like relics from another era when technology moved faster than people did! One such tool we rely heavily upon today however – even though there are many different brands available on site nowadays–is still going strong.

Stated accuracy of the battery tester: ± 5.0%


This battery tester is the perfect tool for diagnosing your batteries. It can determine whether or not there’s current drain, and it does so by measuring voltage rather than amperage–which means you don’t need any specialized equipment like multimeters with 10A ratings! This type of meter would be able to perform this diagnostic check but only if they have at least 20 amps worth in output capacity.”

Design and Build Quality

The Innova 3320 multimeter is lightweight, side-mounted lead holders make it easy to carry around while you work in your home or on the car. It also comes with a stand that folds out when needed! The battery compartment can be accessed easily through two screws and there are long probes so no need for trimming them before using this device.

The dial is central and slightly proud with 13 selector stations – four of which are dedicated to the battery tester. It also has a lock function, something you would expect on any cheap meter as it doesn’t take up much room or add extra costs for features that aren’t necessary at this price point (but does have most).

Display and Labels

The large, clear display and digits on the 3320 multimeter will catch your eye. The unit is not backlit though so it doesn’t have that extra edge over other units in its class but still impresses with professional features such as labels clearly labeled “mV” or AC voltage indicator at bottom left corner when batteries are low.”

Function and Performance

The Innova multimeter is perfect for any professional with busy schedules. With three different jack sockets, it can be used in most settings without hassle and offers an auto power-off function that saves on batteries! The board has good components which should last you a while thanks to their high quality construction alongside reaction times being respectable given this gadget’s price point–I really like how quickly everything loads when I open up my app store screen.


The 3320 multimeter has an attached rubber holster with corner guards that protect it when dropped.electrically, overload protection is only for lower ranges and on the higher amperes there’s no fuse so you must be careful not to shock yourself or others by touching exposed parts of this device while operating outside its specifications.

The input resistance is 10MΩ and it can operate at temperatures down to 32°F (0 °C) , making the meter safe for automotive or domestic situations. Industrial meters typically have a wider operational range, but this isn’t needed in most car depots since they are usually kept cold by refrigerated cabinets where these measurements will take place.

Best Suited To..

This multimeter is a great tool for anyone who works with electrical circuits or home appliances. It can diagnose problems in cars, motorcycles and boats while also being good at examining electronic circuitry- not just basic computer networks.


The INNOVA 3320 is the best tester for home and automotive use, but if you need to test high amperage AC circuits or three phase systems then it may be time to consider investing in something more substantial. It has most other features which make up its value-able proposition; large display screen with battery checker auto ranging capabilities among others.
