That means for example, that for 1.000A current your meter has accuracy of 1.000A+-1mA, so what the point of displaying 6-digit value, if you don't actually know last two digits at all?
Thats a very good point! Why adding digits if the accuracy is not there?
I still ordered one because of the bidirectional USB C connectivity.
And the accuracy is good enough for me (for the things i plan to use it for).
It looks like a nice device, but this 6-digit "feature" is nothing but marketing BS with goal to increase sale, because, you know, other similar devices have only 4-digit "accuracy".
The point is your TC66(C) device has useless extra two digits for voltage, current, and power, so why display it if those last two digits are basically noise and contain absolutely no useful information?
you can read their introduction or watch vedio, when you want to use 6-digit accuracy, it is charged by independent power supply and you can see they are not useless, 6-digit accuracy
means the fifth digit is credible,4-digit accuracy means the third digit is credible, that makes the difference.

Regarding CC Pull Down, there is a PD switch as well as a Settings Interface menu item that can both be used to activate the pull down. If one says to pull it down and the other is set to not pull it down, what happens?
Hi friend
in fact, one is software control CC pull down, one is firmware to switch PD , if you want to use PD trigger, you must switch them on … if one was closed, trigger can’t work
for PC software, we just finished yet, but we did not let our foreign friend to help me test first , we have tested, I would like let others test again
if you want to , you can help me test … this is file https://drive.google.com/open?id=1pX_YLL6HNbpq8rhjxmB_QnTtyyCZedur
