Just got a TC66C yesterday. All is ok, pc communications included, i am very satisfied. But i cannot update the firmware (it shipped with 1.12 while there is 1.14 available).
I followed the procedure, pressing K1 while connecting it to the PC: the TC66C shows “BOOTLOADER 1.06” and the pc software says “inserted” but when i click on Update Now the software hangs and do nothing. The display on the T66C keeps showing BOOTLOADER line.
well, my tc66 just stopped turning on when putting in to usb-c after 4 days. Yes, the pwr switch is on, have to hook up a powerbank to the microusb for it to light up.
I got it up again. Did go through the process maybe 6-7 times and its working again.
-pd softswitch off and on
-pd swith on the back off and on
Did that 6-7 times and it finally detected it again. Was testing phone charge so had turned off pd, but seems to have been a bug turning it on again.
on fw 1.14
thank you for your support, and usually it takes 20-25 days to Brazil.\
recently it is fast, one year ago, it is very slow , sometimes it is more than 60 days
RD tech- Im curious as to which charger you are using on page 1 (C66C can test the maximum power of PD charger, so that we can know the quality of our charger)- It looks like it is capable of PPS 45 W
what is name/model number of it?
thanks
Thanks- I don’t mean to hijack the thread but have you come across any chargers that do pps 10v-4.5A (like the samsung 45w charger)? p.s. love the functionality of the TC66!
Hi Guys,
Just a quick question, can we down load the off line filed from the TC66C using the Android app, like you can with the PC software.
Thanks
Dave
Thanks, hopefully this will be addressed in later firmware revisions.
Also as per a previous poster my TC66c failed to restart with only the screen illuminating with a dull glow.
Could get it to boot into the bootloader but and it would talk to the PC via a cable, but it would not measure any voltages or current.
After quite a few reboots it surprisingly came back to life (thank God).
Same story here. This is a great meter with some unfortunate durability problems. To date I have purchased three. I don’t use them for anything crazy; at worst there might be the full weight of another tester on the USB-C connector, but at the moment only one of mine still works. The other two only turn on to a faint glow and don’t pass power through.
When the first one stopped working I thought one of the connectors had a broken solder joint. “Repairing” that broken joint had no effect.
I would be interested in knowing what the problem is, so I can at least take a stab at repairing it properly.
I got a couple of 65W USB PD chargers, one for the car and one for the wall, and tried monitoring the charging of a MacBook Pro with this unit. The MBP says it is charging at 65W and the meter shows 20V but the power displayed jumps around between say 35W and 65W (and the current proportionally).
Sorry if this was covered already, but can the TC66 measure internal resistance of USB-C to USB-C cable, similarly to how UM25C does it for USB-A cables?
