A very versatile and cost effective product. As a generator sales and service company, it is imperative that we are able to perform testing of our customers generator windings. The Amprobe AMB-45 does this and much more in a cost effective platform. I would recommend this to companies such as ours. May 26, 2015
Great Value and User Friendly I have used this meter for quite some time and have found it to be very accurate and easy to use. When I have loaned it to others they have quickly put the features to good use. May 26, 2015
I enjoy my AMB-45. It's simple to use and has convenient options. I enjoy my AMB-45. It's simple to use and has convenient options. I enjoy the timer function that allows for easy cable testing or hands free operation. The built in volt and ohm meter lets me to quick safety checks with one tool prior to megging. I've also tested the output several times and it is within 1v of the stated output every time. The battery also has decent usage life, although I've never used it for more than a hour or two at a time. I'm a real user / electrician NOT someone paid to post product feedback. January 27, 2015
Full featured insulation testing multimeter The AMB-45 has met and exceeded my needs in a insulation testing meter. It has just the right features that compliment the testing that do on bus duct and switch gear.The high volt and low ohm features go hand in hand with this type of meter and the memory and record feature that lets me download to my computer is just brilliant . This meter comes with everything I needed and at a very reasonable price. Well Done Amprobe Co. November 20, 2011
