Klein Tools MM400 Multimeter, Digital Auto Ranging, AC/DC Voltage, Current, Capacitance, Frequency, Duty-Cycle, Diode, Continuity, Temp 600V

Excellent meter; much better than previous meter and a good value.

It is a very well built instrument. Feels solid to the touch and a lot of thoughtful features have been built into the design - such as a removable protective shield for the probe tips. It was easy to set up and use. Highly recommend!

I love the affordability of this product, works as designed only complaint would be the leads are pretty short

I had not used this since I purchased, and recently tried to get voltage readings on some batteries and the display was jumping all over the place, replaced batteries in the unit and still same issue.

I had fluke meters this is as good as a fluke but less expensive great for the money

Needed a replacement meter since my craftsman’s batteries leaked and destroyed my meter. However I used my old leads because I’m not a fan of the ones it comes with (little contact points on the leads). But overall a solid budget friendly meter.

I watched and read a number of positive expert-level reviews on the Klein MM1000 and MM2000 meters. I was sold. But, those meters are discontinued. The MM400 I purchased here is one of the lower cost models, so I wasn’t expecting as much.

Use for general measurements

I had an electrician that came to my house an forgot his meter used mine short story In his words great product

I was going to buy a high quality fluke meter and got talked into buying this junk. I used it about twice and then it quit measuring voltage. I checked the batteries and fuses and it still didnt work. Into the trash it went and off I went to buy a fluke. Dont waste your money.
