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.

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!

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. The battery test goes beyond just measuring the voltage of the battery any cheap meter can do that all day long. The battery test function in the 3320 puts the battery under a current load (10 Milli amps for both 1.5v and 9v batteries) and then measures the voltage. This gives you a much better idea of if the battery is really good or not and will really perform in your devices. Some batteries on a bare voltage test show good voltage, but that good voltage will quickly drop to unusable levels once the battery is put under load. So testing batteries with a meter that has a battery test function is far superior to just checking it's voltage. This feature alone makes the $19 price for this meter well worth it!

As a few other reviewers have said, it can only measure 200 Milli Amps of current in AC (whereas DC can measure up to 10 Amps). Most other multimeters can measure 10 amps of DC or AC current. So if you are looking to measure any substantial AC current this is the wrong meter. In fact for any current measurements I recommend a current clamp like the ExTech 623 or ExTech 380942 since you can clamp right over a live insulated wire (while the circuit is operating) and take your measurement. With any standard multimeter (like the 3320) you have to wire it in line with the circuit first (with the circuit powered off) and then you can take your measurement. But if you are looking for a compact, accurate multimeter for your garage or home (where you will not need AC current measurements) then look no further you cannot beat the accuracy, auto ranging speed, and the price of the Equus 3320.

Honest reviews on INNOVA 3320 Auto-Ranging Digital Multimeter

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.

I received the Equus multimeter about a month ago. I've used it very frequently at home checking batteries, home appliances etc.. My conclusion is that the Equus Multimeter is worth every penny I paid for it. It is shock resistant, (I dropped it from a 4' stand and nothing happened to it). Is accurate, the auto power off feature is very useful. You don't need any more for home use.
