Just thought I'd share this, don't leave your UT61E in the sun, the screen will turn black. After cooling it down it recovered. My Fluke 101 and a cheapo Ohmeron mt488e didn't have this "problem". |

That's not specific to the UT61E, it happens to almost all LCD displays |

The meter has had several modifications done to it at this point. Yes, I did modify the reference to attempt to make it more stable with temperature. Originally it was one of the least stable meters I looked it. It's actually more stable now than many of the meters I have. I also changed out the 10T trimmer pot while I was at it, assuming this was the major contributor. It did not turn out to be the problem and I just left the new part in there. |
