TC66C-a powerful Type-C USB tester

I asked them and they told me that thay started shipping but they need time to Pack so many orders :cry:

we can only wait, and they won’t like disputes so they will send your package in time, :face_with_monocle:

"-6digit voltage and current, resolution is 0.0001V(0.1mV)/ 0.00001A(0.01mA)"

What is the accuracy in % for voltage and current readings?

Voltage measurement accuracy:±(0.05%+10digits at 23℃)
Current measurement accuracy: ±(0.1%+20 digits, at 23℃)
written in its Technical Parameters :crown:

My order is shipped. No the long wait beginns.

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?

To see fluctuations?

Sounds like they are still writing the software, while the devices are on their way to the customers.

Lucky for them, they still have about a month or so to finish coding it. :slight_smile:

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".

It depends on users. Usually 4-digit “accuracy” is enough, but it can not meet everyone’s needs, so we just choose the device what we need :smiley:

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.
if you want to know more,please contact RD offcial ,I’m not the designer :nerd_face:

Thank you for your article, it helps a lot. If other friends have interest in TC66C, you can contact me and I am willing to communicate with you

When will the PC software be released?

it should be this week, don’t worry, when you get the products, you will see the PC software

Got my meter today. Software not yet available though.

you get the products ? I will put the PC software fast …

I just got my unit!

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?

And I still don’t see the PC software anywhere.

Thanks.

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
