Uni-T launches the UT117C multimeter
geb:
I understand Dave's point about the marketing of this meter, but I think UNI-T wanted something they could differentiate from Fluke's 117C, and wanted to grab some of the "I NEED a lot of counts" market. Some non-electrician might see the 60000 counts and grab it.
This meter has felt like it has a lot of potential to be my daily grab-and-go DMM, which lately has been a calibrated B41T+. The LCD is more readable than my other cheap meters. The input protection seems good enough that I could loan it to a non-technical friend and get it back in one piece. It's cheap enough that I don't mind abusing it.
I'm starting to compare it to UT181A, having seen N8FDY's review. I saw his AD584KH readings. When you pay USD350 for a UNI-T 60000 count meter, apparently they remember to calibrate it to within a digit. :P
I could get interested in hacking the MCU and adding a mA (and possibly uA?) mode. I didn't try reading out the firmware. I have limited time for playing with it at the moment.
I'd like to see more samples of dumped EEPROMs from other UT117C owners. I'll note that my EEPROM contents don't look like DreamTech's usual work (DTM0660 and whatever modified stuff is in my RM303). A bit of side-trivia, partially unconfirmed: DTM0660 seems to store a master voltage value, referenced to 500mV, at offsets 22H-23H in EEPROM. I changed a shunt voltage reference in a meter, recalibrated only its millivolt level, and the rest of the modes became as accurate as they'd been before the change. It would be nice if such a thing existed in UT117C. I could recalibrate one setting and all of my 5-digit-off readings might fall into line. One can dream, right? :)

I just tested the power consumption of UT117C.

Update: Turning on the backlight will increase the current consumption by about 2mA.

Here is mine.

I was thinking of getting a new multimeter. Would you recommend ut117c or Brymen BM789

I'd say that's a no-brainer. Brymen BM789 for nearly any use case I can think of. Especially if your use case if primarily bench electronics work.
You might also consider Dave's eevBlog branded BM786, which you can get from Amazon in the US. Otherwise you're looking to import from an EU dealer since Brymen doesn't authorize their branded meters to be sold directly in the US. Greenlee is the main US seller of rebranded Brymen meters with good US warranty & support, but at a premium cost compared to the OEM Brymen models. I can recommend the German retailer Welectron if you choose to buy other Brymen models. They have great prices, low cost & fast shipping to US, and no sales tax. But you'll get no warranty or support from Brymen.
