Uni-T launches the UT117C multimeter

Mine just arrived -- order was placed on the 12th so technically it took 15 days.

The package was wrapped in Uni-T tape so it stands to reason it came directly from Uni-T -- i.e. the Aliexpress seller simply placed a drop-ship order.

My bundle of the UT117C + clamp meter also came with an oversized mouse pad -- not sure what I'm going to use it for.

My ut117c have a precision above 0.1% (compare with philips pm2525). Resistance readings also overestimate on precise resistors (+ 0.1%)

     I am also in the USA and ordered mine on Aug 2nd, so should get mine in 15 days?.....I hope :-DMM

Hi! Just joined the forum.

I received my UT117C from Aliexpress a couple of weeks ago. Played with it before leaving for a vacation.

I backed up its 24C02 EEPROM. I tested it against an AD584KH, a pile of 0.01% resistors, a VREF-01, my handmade 1-5-10V reference, and some low-cost reference gadgets (e.g. LB06). When testing voltages, I didn't trust the voltage reference, and instead compared the UT117C's reading to that of my Agilent 34401.

To make a long story short, it seems to be uniformly inaccurate. I mean, voltage ranges are reading roughly 6 digits high and resistance ranges are about 6 digits low.

I want to figure out how to access its calibration menu. Unless someone has already solved that topic and can offer a quick reply, I'll eventually ask that question in a separate thread. I found an unusual menu by holding buttons during power-on but didn't go further.

I've calibrated a small stack of meters using my materials, and been pretty pleased with the result. My ZT-102 is basically perfect (and unlocked to 9999 count using AN8008 EEPROM's limit settings). One of my RM303s is quite good (and its EEPROM stores individual calibrations for each resistance range, unusual for a 12P65-based meter). My Owon B41T+ had the worst rated accuracy but it is a newer revision with a multiturn pot for DC and its DCV is good after a lot of tweaking.
