    • "Nice" by joelsampson on 3/26/2014
      Overall: 4.5 out of 5
      Value:
      Quality:

      It's a good meter at any price. I got it on sale from MCM and it was a bargain. It measures about everything and it's nice to have an ac powered meter on the bench. The display is large and easy to read. It seems you can measure most things with just the COM and V jacks, which is not what the manual says.

      My gripe is the power switch is on the back, not the front. It's not good for my setup, so I plugged it into a remote controlled power strip.

    • "Excellent meter" by alval43209 on 8/28/2012

      I am an electronic hobbyist, and I have had the meter for a little over a year. I do not do PC uploads, but I do find the meter excellent for giving me readings on my projects. Excellent quality, great functionality, and easy to use. Yes, the power button is on the rear of the machine, but I do not have difficulty reaching over the top and turning it on. The only problem my jaring the power plug (also on the back of the meter) and then trying to figure out why the meter is not powering up. I am very satisfied with the meter.

      Accurate but readings are unstable on low ohms and low volts ranges.

    • "Great meter, no so great software" by dgille on 6/8/2010
      Overall: 4 out of 5
      Value:
      Quality:

      This is a great meter! Extremely accurate and reliable. The display is clear and bright, readable from a distance if needed. I would prefer that the power switch be placed on the front panel and not on the back). I tend to need print outs of meter readings and settings. The software provided does attempt to show what the meter is reading but has no concept of scale. The readings get placed on graphs with no decimal point scaling. The graphs are just very large integer numbers that have to be scaled by hand / mind (not very useful if you intend to send them to a remote engineering team. If you plan to use the meter for it's great accuracy and display it's a must buy, but for PC software use, find another MCM meter/software package.
