0. Download and unzip the independent firmware package at the end of this page (the file name is version number, for example, is V1.00.62)
1. Cut off the power supply of the meter.
2. Turn the trackwheel to the left and hold.
3. Connect the meter to the computer through the connection port (micro-USB port) (at this time, the dial is still pressed to the left).
4. After almost two seconds, the header screen displays the words "Bootlodaer..." and the computer recognizes a disk.
5. You can release the button.
6. Create the "FW" directory in the newly recognized disk and copy the files you just decompressed into it. (Structure such as "u-disk:/FW/…")
7. Wait for the copy to complete.

I don't see differences to CT-2

1. Provide lua API, user independent programming, convenient for batch testing.
2. Support expansion modules (currently only one load module SM-LD-00, other modules with rich functions are under development).
3. A more powerful host computer.
4. Internal 12MB user storage space for storing user programs (user programs can also write files to this space), offline recording.
5. The VBUS ripple can be viewed through the 3.2Msps ADC.
6. Larger screen (2.0' 128*160).
7. The (Super)VOOC/DASH special identification line is straight through, and can be directly measured without additional leads.
8. Added buzzer for better user experience.
9. Added a gravity sensor to automatically turn the screen.
10. Full font support, user programs can directly display Chinese, Japanese and Korean strings.
11. (Super) VOOC/DASH cable reading and identification.

I have the AVHzY CT-2 and have now purchased the AVHzY CT-3 that I have received in Spain and which I am very happy with.

1) Would it be possible to customize a logo and colors of voltage numbers and others parameters on the AVHzY CT-3 as on the AVHzY CT-2?

2) What is the reason that the female USB-A port is on the AVHzY CT-3 upside down to the AVHzY CT-2?
It's the only thing I don't like about the CT-3.

For the rest I am very happy and I look forward to prompt updates that allow further customization of the CT-3.

In windows 10-64bits it is necessary to disable the use of signed drivers so that the device is accessible ...

1) Home
2) Configuration
3) Update and security
4) Recovery
5) Advanced startup ... restart now
6) Troubleshoot
7) Advanced options
8) See more recovery options
9) Startup settings
10) Restart
11) Disable mandatory use of signed drivers ... press key number 7

There is a bug with Fastcharge Auto Enum function in firmware 10044 and Xiaomi MDY-08-EI QC3 charger.
There is a loop software and is not possible to exit.
Is needed reconnect the CT3 usb meter in other power source that Fastcharge Auto Enum works ok.

The bug is using a USB-A to C cable connected on usb-c in and with no load atached.
I have tested other cable and the bug is.
But if I have a charge (0.28A for example) atached to usb-c port-out the bug is not happen.
