This tool offers multiple functions that allows the professional worker to carry one meter into the field instead of several. The autoranging EX430 measures AC/DC voltage, AC/DC current, resistance, diode, continuity, capacitance, and frequency, all with +/-0.5 percent basic accuracy. This unit has a low current capability, measuring down to 0.1uA, and features input fuse protection and mis-connection warnings. A Type K thermometer is built in for surface or air temperature measurements.

CAT III test leads are included. And for greater convenience, the unit comes with a multi-position tilt stand, a Velcro strap for hanging, and a protective holster with handy test lead holder.

True RMS Prevents Distortion from Electronic Devices
It can be very difficult to make accurate current and voltage readings in industrial and commercial applications when electronic devices are present. Fluorescent lights, motor drives, computer power supplies, and other electronic systems can distort the AC waveform, making it hard for averaging meters to get an accurate read. True RMS uses a more advanced formula to compensate for this kind of distortion.

Large, Backlit LCD Screen For Easy Reading
Readings on the EX430 are displayed on large, backlit LCD screen with easy-to-read, 1-inch-tall digits. The 2,000-count screen offers high resolution over wide ranges, and features data hold. To preserve your batteries, the unit has auto power-off.

Compact, Ergonomic Design for Comfortable Handling
The EX430 is ergonomically designed and weighs less than 1 pound, so it offers a comfortable grip for one-handed operation. It measures a slim 7-2/5 by 3-1/5 by 2 inches (H x W x D), and uses one 9-volt battery.

Warranty Information
The Extech EX430 11-Function Professional MultiMeter is backed by a manufacturer's three-year limited warranty on parts and labor.

What's in the Box
Multimeter, CAT III test leads, stand, hanging strap, holster with built-in test lead storage, Type K bead wire temperature probe, battery, and owner manual.

It works well EXCEPT only a month or 2 into owning it (about 2 years now) the main dial stopped correctly working. Only in that the unit will not turn on unless I slowly move it over the detents to the value I'm requiring. Otherwise, it has matched up to Fluke in most metering respects..

I bought this to test my grounding / earthing equipment and a show my friends the difference between not being grounded and grounded. It works great! I briefly thought it was broken when the symbol OL showed up, but after read the directions I realized I was just overloading it on the setting I had it on. Changed it to a higher setting and I was fine. It has the lowest setting you needed, millivolts , To test grounding equipment

Great basic multimeter at an affordable price. Easy to use, has all the features a DIYer may need. I have worked with Flukes before, and while I agree they are great, much of what you pay for is the name. You are much better off saving your money and going for this meter.

Reviewed in the United States on April 9, 2016

I bought this (on Amazon) because another worker I respect has had one for years and it's 20 amp DC at the leads instead of the standard 10 amp. Now, however, I regret purchasing it and just use the Elenco ST-3030 purchased at the same time although it's clunky with the leads (awesome at the clamp though- review pending).

So, this thing works, is accurate and if the build quality wasn't so abysmal I'd give it 4 stars for doing what I want it do.
But build quality is poo. This all started a month after purchase and has progressed since. First: It wouldn't turn on unless spinning the dial till it made a noise then back to Volts. Fine, co-worker says that happens to his also.

Then the Ground plug loosened up inside the unit and became woobly- I'm with a customer testing their solar panel and I have to excuse myself to hit a nearby battery so I can wiggle the negative connection till it works and shows the battery voltage then hope it stays in place back to the solar panel? Unrealiable, unacceptiable.

Then I took the thing apart to see what was up and my review ends here since..yea, it's gathering dust till I can 'fix' it.
And a note, I don't return anything unless there's a blatant error or flaw- this worked great for a month and degraded. Bad unit? Maybe, don't care- the unrealiablility of build quality killed it for me.

I've only used it a bit, but I love it. It's just as good as the FLUKE I use in my lab, and 1/4 the price. I didn't even realize it came with a thermometer probe, which was an AWESOME surprise, considering I'm building a temperature controlled homebrew vessel.... Now I have something to validate my other sensors with.

Awesome product so far. According to other reviews, don't blow your fuse!

Extech: Turning the selector knob does not always work. I had to turn it back and forth(repeatedly at times) to get it to come on. Continuity test buzzer doesn't work sometimes when I touch the leads, so I'm doubting its validity(and other settings) while testing.

Amazon/UPS: would help if your return process was easier. I don't own a printer now(Of the ones I've owned, the ink always dried up or jets clogged). I need the multi-meter now. I feel your return policy should let customers receive a new one and still have enough time after It's received, before sending the old one back.
