LeonR, agreed, the UT117C's backlight isn't great. I reached for my nearest DMM, an HP-770D, for a side-by-side check. I'd guess the UT117C had about 60-70% of the lumens of the other.
makz, SEL+REL sounds right. As for comparison, I'm not sure what you're asking.
Out of the box, all the DCV and resistance ranges I tested on my UT117C are about six digits off. This is oddly consistent and made me think they copied the EEPROM from another unit without recalibrating
.
As for some of my other calibrated meters...
The RM303 is rated for better accuracy (0.05%+-3 in DCV) and is now within a digit or two on multiple DCV and resistance ranges after a brief warmup. It's the best resistance accuracy I've seen in a cheap meter so far. I modded the voltage reference but it was nearly as good before this. (Changed ICL8069D to a handpicked ICL8069A with low drift and added a 4.7uF cap across it per datasheet recommendation. Was hoping to get rid of its wobble, 10.000V is 9.999-10.001 every second or two, but the mod only helped a little. Paralleled caps in a few spots also didn't help. Didn't want to try adding a VLCD supply as another modder did.)
The B41T+ is only accurate to 1-2 digits on a short range of DCV. Its linearity as tested across its 2.2-22V range seems a bit off (several digits IIRC) and some other modes don't have their own calibration (no EEPROM, just a few pots). The B41T+ is a good performing meter otherwise, with a fast-responding analog bar graph and fast auto-ranging.
Incidentally, the bar graph on the UT117C is responsive but "noisy", at least during a quick check of around 5.0VDC.
