Click here to watch video

The Amprobe AM-530 autoranging digital multimeter is the multimeter of choice for professional electrical contractors. The AM-530 is a True-rms digital multimeter so it accurately measures voltage on systems affected by harmonics. With its full menu of digital multimeter features, you can use it to: measure and verify the presence of voltage before connecting new equipment or performing repairs; run new wiring; check continuity of electrical connections; identify blown fuses; troubleshoot motors or check transformers. The CAT III 600V safety rating provides an extra measure of safety for high voltage multimeter applications. Its built-in flashlight helps you see wire colors in the dark and “third hand probe holder gives you an extra hand when you need it.

Rated 5 out of 5 by Accurate I am tired of buying meters that are not accurate but this one proven to be accurate time after time January 17, 2016
Rated 5 out of 5 by The meter meets all requirements needed for maintenance of community facilities Working in the multi-family dwelling maintenance field for nearly 25 years, rarely have I found a tool that covers most needs of facility maintenance personnel. Troubleshooting electrical problems with the AM530 is relatively easy and precise. I have used the AM530 "True RMS" in every area of the facilities found at most communities from HVAC, to troubleshooting pool pump and aerator motors. The many features the meter offers are useful and combine functions found in multiple tools. Making the meter versatile whether used to trouble-shoot 5 HP pool pump motors to measuring flame signal from a spark or hot plate ignition furnace system, it's got it all. With the alligator clip leads accessory TL35B telephone troubleshooting DC voltage checks are simplified and accurate. Many other features make it the ideal tool for technicians in the facilities management field. A great meter at a reasonable price. May 29, 2015
Rated 4 out of 5 by GREAT!! he multimeter has a solid feel. The selector switch has well defined detents and the case does not spin if using it on a flat surface. The bail is fine and you can use all of the buttons without difficulty in the upright position except for the 400k Ohm input impedance button. The screen is big and easy to read; the decimal point is always easy to spot. There are two type-k temperature probes that can be attached for simultaneous readings. Past Amprobe multimeters have had an annoying beep when turning the selector switch; thankfully this function has been eliminated. There is also a non-contact voltage sensor function with an audible alarm (a visual warning would have also been good considering that this may be used in noisy environments). Amprobe has been in the electronic test equipment business for many years and made their name with current clamps. They are now owned by the Danaher Corporation which also owns Fluke (both headquartered in Everett, WA). Amprobe markets its products mostly to electricians and HVAC professionals. May 27, 2015
Rated 5 out of 5 by My history with AMPROBE goes back many years When I worked at TV-18 in Milwaukee, WI, I would BORROW the company"s AMPROBE DIGITAL CLAMP-ON meter. Then somebody borrowed it and NEVER RETURNED IT! DENNIS HOYER AUDIO TRANSFORMERS May 26, 2015
Rated 5 out of 5 by Very Good This is being used for school work and I can easily see me using it for other areas. The one concern is it is very easy to blow the MA fuse if not careful. Other than that it does everything I want to include an easy read screen. May 26, 2015
Rated 5 out of 5 by Great Value and Easy to Use I purchased this meter for general electrical and HVAC maintenance work. I have found the meter to be a great value and easy to use. The quality is very good (as has been my experience with all Amprobe tools) and it possesses all the basic functions needed general maintenance. I am hoping Amprobe will market an inexpensive amp-clamp attachment for this meter in the future. April 25, 2015
Rated 3 out of 5 by Rather Disappointed I am rather disappointed with my AM-530 because it is actually very slow in obtaining steady final readings and shortly after purchase it became faulty with intermittently no display visible. I persisted with it for awhile because the fault was intermittent in nature but it failed totally after just a couple of months with eventually no readout visible at all. I then contacted Amprobe Support online about the fault issue and was subsequently contacted by Fluke warranty support from Washington USA who were very good to deal with and who immediately instituted the nescessary process to replace my faulty meter under warranty. Overall I am quite happy with the build quality, the operating features and the price of the meter but the slowness of obtaining final steady test readings and the faulty display issue has unfortunately soured the ownership experience for me.

Rated 5 out of 5 by Very diverse and user friendly functions. For being in the upper mid-range of multi-meters this device is well worth the price. Exceptional design, well thought out and versatile functions. The ability to test capacitance as well as most any other reading makes it great for HVAC work as well as line voltage, resistance, amp draw etc. One of the best meters in it's price range I have found. So much so I have specified it as the meter for 65 apartment community maintenance shops. April 29, 2014
