The TC66C i ordered a few days ago says still processing (processing time 13days). I hope they will shipp it until then. The option to use it bidirectional is really helpfull. It makes checking the charge current (position of the device on the charger ) of my wireless charger much more easy.
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.
