Ideal for electrical troubleshooting, the EX300 series of Digital Multimeters from Extech Instruments includes two meters in one easy-read, conveniently-sized device: a fully featured digital multimeter and a non-contact voltage (NCV) detector. The EX330 measures DC/AC voltage to 600 volts with a 0.5 percent basic accuracy, along with DC/AC current to 10 amps. This feature-rich digital multimeter measures resistance, performs diode testing and continuity testing, has an easy-read LED display, an audible beeper and red LED indicator, and low battery indicator.
Featuring a big digit 4000-count display, the auto-ranging EX330 offers 12 total functions, including frequency, duty cycle, capacitance, and temperature. A built-in thermometer with Type K probe can switch between Fahrenheit and Celsius readings.
Features

|
|
|
|
|---|---|---|---|
AC Voltage DetectorThe built-in, non-contact AC Voltage Detector uses a combination of audible beeper and red LED indicator lights to alert you to the presence of voltage when placed near live wires, outlets, switches and more. |
Large One-Inch DigitsThe EX330's 2000-count LED display features large 1-inch digits for easy reading even in dark or dimly-lit testing environments |
Auto-rangingThe convenient auto-ranging operation allows you to select the right measurement range when working on a variety of components, from small electronics to main electrical sources. |
Max Hold & Data HoldThe Max Hold function allows you to capture the multimeter's highest reading. The display will update each time a higher reading is reached. The Data Hold function allows you to freeze the current display so you can review and take notes on your current reading. |
|
|
|
|
|
|---|---|---|---|
Auto Power OffThe Auto Power Off function powers down your multimeter after 15 minutes of inactivity to help conserve battery life. |
Type K TemperatureThe EX330 comes with a built-in thermometer and Type K bead wire probe for temperature measurements. Temperature measurements can be displayed in either Fahrenheit or Celsius. |
Capacitance & FrequencyThe capacitance option allows you to charge a capacitor with a known current and measure the resulting voltage when performing electrical troubleshooting. The EX330 measures frequency between 0.001Hz to 10MHz for quick and easy diagnostics when testing circuits. |
Relative FunctionThe relative measurement mode makes measurements relative to a stored reference value so you can compare one stored value with another. |
Testing Outlets
Test an AC wall outlet by inserting a test lead into each slot to measure the line voltage.
Testing Appliances
A variety of home electrical problems can cause appliances to malfunction or stop working. Using the resistance setting, test faulty appliances such as ovens, dishwashers, washers and dryers, furnaces and more.
Indoor Household Use
The MN10 can also test other common appliances around the house, including lights, ceiling fans, home theater systems, exhaust hoods/fans, and more.

There was a problem filtering reviews right now. Please try again later.
Also, I read a complaint somewhere about the stand being too flimsy - it's is built into the orange cover. But I think it's fine - it's a stand for the meter. It works. I mean if you were to pull on the leads while using, then yes, I suppose you could knock the meter over, but I have not had this problem. The leads seems good. I also read where getting replacement higher quality leads can be helpful. But the stock leads are great so far. Highly recommend!
Display is large so it's easy to read.
Simple, but precise, dial selector. Housing feels of good quaiky construction for field usage.
Has a nice and useful feature to monitor with a red light on top of housing when an outlet is energized, just by putting the meter close to the outlet.
Like Extech instruments because have good price / performance for non critical field usage.
Keep in mind there are better options for more specialized uses such as an electrician, industrial support, electrical engineer, etc. But as a all rounder that doesn't break the bank I think this is hard to beat.
I can't say enough good things about it, but I'll try to focus on the highest of the highlights: the NCV button! It's so nice to be able to diagnose so many electrical problems just by holding down a button and gently moving the device along a cable or a wall, listening for the spot where the current stops. And it's a great relief to be able to flip an unlabeled (of course) breaker, press the NCV button, and know if that was the switch for the circuit I'm about to work on.
Say I'm on the outside of a trailer, working on the water heater that's only accessible by removing an exterior wall panel. As described above, I've found the breaker that goes to this circuit. But that was yesterday; did my father-in-law flip it back on in the meantime? I'd better get down off of the ladder, walk around the house, and have the lady who lives here walk me back to the bedroom (awkward) where the breaker box is so I can check it, right? No way! I can just hit the NCV button and find out. (And then, just because I've been stung too many times by "disconnected" electric fences back on the farm, I go ahead and test it with the probes to confirm. But it's good.)
I've also used the NCV function to find faults in power cords on sump pumps, among other things. One little nick in the insulation, it turns out, can corrode an entire length of wire... But I digress.
Another great feature is the... What is it called? The one where you switch it to measure resistance and then toggle the mode a couple of times. Then you touch points with the probes and if they're connected (i.e., sufficiently low resistance), it makes a noise. You don't even have to look at the meter! It's great. I use that all the time to see which points in one place match up to which points in another place. Handy for when wires change colors on the other side of something that would be a pain to move, and the audible signal means I can focus on touching the right points instead of trying to watch the display.
I've used most of the functions at one time or another, but those are the most common ones for me. At work yesterday, I fixed a multi-thousand-dollar refrigerated centrifuge with it by using a combination of the DC voltmeter, ohmmeter, and frequency functions. I've fixed a lot of other things with it, too, but that was all for yesterday.
I'm not an electrician or anything, just a guy who likes to tinker with stuff and works in a laboratory. I really ought to have my boss invest in one of these for the lab so that I won't have to keep carrying mine back and forth from home. I've gotten to the point where I look at it and think, "If I don't take it with me, I'm sure to need it." And it's true.
Despite my enthusiasm for it, there are a few things I would change about it if I could:
1. I would include some leads with alligator clips with it. Come on, those are just too handy not to have. I suppose I can buy them separately, but it would have been nice to include them.
2. I really wish it had some little clips on the side to hold the probes. I have to wrap the wires around it or let them dangle; neither is satisfactory, and both leave you with surprisingly sharp points sticking out. I guess I should invest in a nice rubber band, and maybe something to cap the points. I don't know, like I said, I'm not a professional or anything.
3. The temperature probe is a separate attachment that I almost never have with me, because who wants to carry that, too? I don't know how to fix this, but it would be nice if it could be improved somehow. Also, the cable for the temp probe is really stiff. I don't know how necessary that is for the functionality of it, but if it could be as pliable as the two contact probes (or leads, whatever; I'm an amateur), that would be a step in the right direction. I'm kind of worried about it snapping due to metal fatigue, honestly. It's that stiff.
