This multi-meter is a general-purpose instrument designed for use in general electronics, home electrical applications, and automotive electrical and electronic systems. It has auto-ranging scales which eliminate the need to dial in the correct range when making electronic measurements. The 10-megohm input is safe for automotive and household uses like fuses, wiring, general-purpose batteries, and automotive circuits. It has a color-coded LED which displays a battery quick check, showing green for good, yellow for weak and red for replacement. It also comes with protective rubber corner guards for drop protection. This meter is designed to test AC or DC voltage, batteries, AC and DC currents, resistance, diodes, and continuity.

   Has all the functions of a much more expensive meter. The only fault that could be found is that the rubber holders to secure the leads are totally ineffective, but this is minor.

   Very good purchase.

   This meter will serve for general home use but is nothing special. The case clips that hold the lead contacts are very weak and useless.

   The Equus 3320 Auto-Ranging Digital Multimeter I bought is a handy, reasonably priced meter for general use around the house or boat.

   So far, so good. Excellent meter, nice display and works very well and is easy to use. It’s a lot of meter for the price.

   Having 3 of the good old Radio Shack analog meters at home, one of which works but in limited ranges, I needed a new one that read over 1M ohms. Did some research and this one seemed to fit the bill. And it does. Probes seem of good quality and they go in their socket at an angle, unlike the straight on RS ones which then can break off. Good size. Has a wrist strap so you don’t have to hold it in your hand and also try and manipulate both leads. The surprise for me was the battery tester. This is NOT just a voltage tester. It puts a load on the battery to tell whether it’s usable. So the 9V battery from my smoke alarm tests at 9V but the alarm said ‘low battery’. Testing with this device and, lo and behold, under load they’re only 6.3V (in addition to lighting the appropriate LED, the device also reads the voltage)! Having looked at battery load testers, and finding them more expensive than this device, I was extremely pleased to find out that this wasn’t just a battery voltage reader. The aggravation saved in using ‘good’ but actually not good batteries (“I don’t get it. The batteries test out just fine. Why doesn’t the stupid flashlight work?”) is worth the price all by itself. I can’t comment on durability or range-jumping, as I haven’t had it a long time and do not do fine fuel-injection testing as one other reviewer does. Perhaps the automotive version would have been better for them. I did notice that the read-out does jump around if you aren’t holding the probes absolutely still, so clips work better. Great tool and I’m delighted to have it.
