Customer Questions & Answers, INNOVA 3320 Auto-Ranging Digital Multimeter

A:I am searching for current leak in a boat (12v battery). Will this dial down to low enough amps to diagnose? Thanks.

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 funct… see more

A: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!

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.

You really want a CAT 3 meter if you want to measure any live breake… see more

A:Does this test 3.6v batteries? (Can't tell if the dial across the battery test range is continuous or discrete points.)
This tester will show any voltage across its probes, AC or DC. So, the answer is yes, it will register 3.6 if your battery is good. It is a good tester, the only downside being the letters around the dial are in dark ink on a dark background. You may need a flashlight to set the dial.

A:What's the lowest ohm reading it is capable of? 0.01? 0.1? 1.0?

0.001. Love mine. Works great.

I completly Love this Meter!!

This little meter is outstanding! I own a Fluke DMM 179 and of course that meter is top of the line. But would you believe this Equus 3320 is 99% spot on with it's readings when compared to a recently calibrated Fluke 179!! I compared measurements with the Equus 3320 and the Fluke 179, in AC Voltage, DC Voltage, Resistance, and DC voltage for the Equus in the Battery test modes. It had literally almost identical readings to the Fluke! The circuit board appears to use mostly prime spec electrical components, so I suspect it will remain accurate for a long time as long as it's not abused.

This meter sells on Amazon for less than $20, and has auto ranging. This means instead of having to dial in the max value manually the meter figures out what DCV range to use (if you were measuring DC voltage for example). It's the same deal for other measurements like resistance, AC Voltage, etc, just set to that measurement type and the meter figures out the correct max range. Most auto ranging meters below $99 have slow auto ranging acquisition speed (this is the time it takes for the meter to figure out what range to use). Many of the cheaper auto ranging meters take several seconds to figure out the correct range and then display the measurement. Not the $19 Equus 3320, it was just as fast as the Fluke 179, which is a second or less in the voltage measurements, and under 2 seconds for resistance (resistance auto ranging takes slightly longer on all meters because the meter must send a small amount of current across the device under test first before trying to acquire the range).

The battery test function (which my Fluke 179 does not have) is the main reason I purchased this meter.

It's OK but could be better

Let's start by realizing this is a low cost meter. It has some nice features but also some short comings.
I like the size and shape. The display is very easy to read and the battery meter works nicely even with NiMH AA batteries. The probe storage is also nice.
The resistance auto ranging is reasonably quick. If you ever have to measure a series of say under 100 ohm resistors or tweak a variable resistor with a low resistance value the longer delay of some auto ranging meters can really be quite frustrating. While the wrist strap seems like a bit of a gimmick, I can actually see it being quite useful.

That said the meter has a number of flaws.
-I don't like that it doesn't have a battery door. You have to unscrew the back case to replace the batteries. The case is held in with self tapping plastic screws. It you aren't careful those self tapping screws will strip out the screw holes in short order.
-The leads are rather cheap feeling. They aren't as lousy as the $3 meters but they aren't as good as I've seen on other $20-30 meters. They have rather dull tips and the surface resistance seems rather high. Cleaning with alcohol would probably help.
-The continuity test is slow to trigger. Like the need to check resistance quickly, if you are checking say a number of wires for a good connection, it's frustrating to wait for the check delay to complete. In defense of the meter, this is slow even on some meters costing $100 or more. This one is also latched so it gives a solid beep once it sees continuity. Some meters sound very scratchy when checking continuity.

Safety concerns.
Let's be honest, this is a cheap meter that should never be used on anything more than a standard household wall outlet.

Good Meter
By Keel Moose and Squirrel on November 16, 2007

This is a good little meter.

Thumb uppers: Small overall size, large LCD display, auto-ranging, uses 2 AA batteries, uses standard sized banana plugs so is compatible with several 3rd party or customized probes/connectors.

Thumb downers: probe clips are such weak, soft rubber that they don't grip the probes securely. And it would be nice for a little more $$ to include a case. So instead buy a $3 camera case to solve both deficiencies. Too bad the over-sized instruction booklet isn't the same size as the meter so it can be stored in the same case.

Good meter but...
By S. Harris on January 25, 2008
This is a meter of above average quality for the price. A great meter to have for the do it your-selfer for around the house, car or boat. However, one function that is lacking is high range AC current (amps) the description says it measures AC current but doesn't say that the max AC amps it can test is 200mA or .2 amps, not really practical for ANY AC current measurments. You can measure the current of say a 20 watt AC light bulb with this meter. The PC you are using to read this draws about 3.5-4 AMPS or about 3500-4000 milli amps, this meter maxes out at 200 ma.

I bought it for AC amps but can't use it for that. I'll keep it as a back up meter but I have to buy a better meter for AC amps. I guess that's what I get for being a cheap skate... time to buy a Fluke!

Amazing Value and Function

I use expensive fluke DMMs all of the time at work and was going to buy one for home use when my Sears DMM (that was pretty much a piece of junk, couldn't auto range, and eventually wouldn't shutoff) started annoying me. So, I chose a $129 Fluke meter then happened upon this meter. I figured what the heck for $25 and decided to order it. If you need a home meter that AUTORANGES (this is a big deal) and works, you really can't go wrong with this product. The autoranging is great, VDC, VAC, & continuity have tested fine thus far and I think the leads are like any other DMM I have used. This is a killer deal for $25.00.
