I just purchased an EXTECH 800Amp AC/DC True RMS clamp meter, model EX730. I was quite surprised shopping Sears when I came across this meter as it is identical hands down. The EXTECH is covered with Craftsman but all the layout and lettering is the same. I looked at the manual and compared it to my EXTECH manual and is like a photo copy so convinced this is the OEM maker for this product. I purched it because the reviews were quite high and it has outstanding features and high in accuracy when compared to others with same features and accuracy costing way more. I am mad that the real EXTECH is >$40.00 higher in price from ****** for this same meter so wished I had came across this one first to save money. The only difference is the case color. I have not compared with others for accuracy and just received it so can't speak to satisfaction yet.
I needed to replace a meter that i use everyday in the hvac field. I saw the capabilities of what this meter could do and thought it would be ideal. The very first chance I had to use this meter will also be the last. Working on a rooftop unit that was blowing fuses, I was trying to track down an obvious short. I replaced wiring from the disconnect to the unit because this meter showed resistance between two of the three wires (3-phase) and ground with the wires disconnected form the unit. After replacing the wires I checked again and this meter still showed resistance on the wiring. I had to borrow a maintenance mans meter to finish diagnosing the equipment. Not only did I waste man-hours, I feel that I looked incompetent to my customer. In all fairness, the voltage, ammeter, and capacitance parts of the meter seem to function properly. If I can't ohm out components or check for continuity accurately, I don't trust the other readings the meter shows.
I am a HVAC Tech I use this tool on a daily basis. This is an excellent tool for the price with just as good of quality as a Klein meter. Offers lots of features AC DC voltage, capacitor reader, temperature, ohms, and other things I don't use. The only knock on this meter is that the temperature probe is not accurate. But if your a real HVAC tech you wouldn't use the temp probe on an electrical meter you would own a cooper thermal couple.
Great deal for the money.
I am an HVAC/R tech. I bought this meter about 10 years ago as a 2nd meter, for the last 6 or 7 years it has been my primary meter. It's on it's 3rd or 4th case, but the meter still works great, I used it today! For what this meter does, the other major brand comparable meter would be about 4 or 5 times more expensive. BTW I bought this meter when it was a new model, it cost more 10 years ago than it does today!
I waited for a sale to purchase this better quality ammeter. I'm no expert, but it seems to work well and has a nice carrying case.
I bought this to work on generators and the hertz reading are all over the place!! Not accurate at all!! I had to buy another for the job and sears would not return the meter!!!!! I am stuck with it and not tooo happy!!!!! Sears is not what it use to be a friendly and knowledgeable store. The associate had no clue about the meter just told me it was electronics and they would not return the item as it was 9 days since i bought the meter!!! It was used and could not offer to repair or replace!!! So Sears sorry for your luck I am now buying my tools and METERS somewhere else. No wonder your going broke!!!!!
As a car audio SPL competitor, a good clamp meter is an import device in your tool bag. Although this clamp is a little slower than a Fluke, it is a good meter for the price. You get a clamp capable of metering AC as well as DC amperage for the same cost or cheaper than a Fluke that will only meter AC amperage.
My man loves this amp meter! Very well made too!
