Customer Reviews

Good deal
I'm a big fan of the high-end Flukes so I've worked with the best. Well, these defintitely aren't the best, but you can't beat what you get for the price. I got it for my brother for his car and it does the job well.

First, the bad:
1. No auto shut-off. You gotta make sure you turn it off or the battery will just keep draining away.
2. No auto-sensing. You gotta set the dial for the range you're looking for. But hey, I like it so much I don't care that I can't be so lazy.

And the good:
1. All the features. You get all the standards PLUS a tach and a dwell-meter! That'll about cover your carbureted cars.
2. Price. You can find multimeters that can't do the extras for the same price and even more. Great bargain.
3. Alligator clips. Simple things but it'd be a pain without them.

Plus, this thing will handle all the home electrical work.

As for the rest: I won't vouch for its durability but Actron is a decent company. They go towards affordable but not junky. The case is made of a light plastic, but it doesn't seem fragile. As for the tolerances, they're not bad:
DC Volts

Accuracy : ±(0.5% rdg + 5 dgts)
Range: 1000V
Accuracy: ±(0.8% rdg + 5 dgts)

AC Volts
Range: 2V, 20V, 200V
Accuracy : ±(0.8% rdg + 5 dgts)
Range: 750V
Accuracy: ±(1.0% rdg + 4 dgts)

DC Current
Range: 200mA
Accuracy: ±(0.8% rdg + 5 dgts)
Range: 10A
Accuracy: ±(1.2% rdg + 5 dgts)

Resistance
Range: 200Ω, 2KΩ, 20KΩ, 200KΩ, 2MΩ
Accuracy: ±(0.8% rdg + 5 dgts)
Range: 20MΩ
Accuracy: ±(1.5% rdg + 5 dgts)

Dwell
Range: 4CYL, 6CYL, 8CYL
Accuracy: ±(3.0% rdg + 5 dgts)

RPM
Range: 4CYL, 6CYL, 8CYL
Accuracy: ±(3.0% rdg + 5 dgts)

Audible Continuity
Buzzer sounds at approximately less
than 30-50 Ohms.

So for the price, a good deal.

Excellent Tool!
This multimeter is an all around good tool. It has all the features you need plus some of the features that only the more expensive ones have. Like the battery tester and backlight display. I am studying electronics right now and I find myself getting a ton more use out of it than I thought I would. It is easy to use and the instruction manual that comes with it tells you how to perform most common tests that it does with pictures to go along. There are comperable multi-meters out there that cost less but most would cost more. There are certainly better multi-meters than this one but they will cost more. The only bad things I can say about this tool is that the battery is hard to get to. You have to remove 2 screws in the back and pry it apart. Actron should have just put one of those slide off battery covers on it. Also most multi-meters come with some sort of rubber, protective sleeve, that also has a lanyard for your hand so you dont drop it. If this mult-meter had a lanyard and the battery was easier to get out, I would have given it a 5 Stars.

VOM for classic car
This will perform any test a neophyte electrician will do. The instruction manual is well written and understandable. Instructions provided for most ignition tests of classic cars and sensor testing of newer cars.
