Review: I am pretty happy with this multimeter, but there is room for improvement. First, the dang thing beeps every 10 or 15 minutes to remind you it's still on. The beep even occurs when you bypass the auto-off function! Second, the display is not as easy to read as other meters in this price range. I see a lot of reflection off the plastic lens, and the LCD display is not super bright. Lastly, there is a big chunk of plastic on the top of the backside that keeps the unit from lying flat. I suppose this is to accommodate the leads while in transit. MY unit stays on my bench.
Review: Excellent device, was looking to purchase one long time. This is the best for its price and functionality.

## Questions & Answers

**Q: I'm finding conflicting information. does the ut139e have a black ebtn display like the ut139s?**
A: Hi, the UT139e has a regular display, black numerals over a light background. The UT139s has the black EBTN display. I have the “e” model and it’s fine, but I can see how the reverse contrast background might be more legible under certain lighting conditions.

*by J***N on 29 March 2025*

Very nice meter. I did not everything I would use the NCV feature on this meter but had to change a tankless hot water heater and wanted to make sure that power was actually off. Just held the meter to the the wire going to the unit and verified it was off. No reason to use the leads. Also noticed this works with USB cords as well to see if they have power at the end. I also work on analog power supplies which will have large capacitors on them. This unit is able to measure these which my old meter would not. So far I am very pleased with this meter.
