ATorch T3 USB-C Tester Firmware Update v2.0.6 Available - 4-Wire Resistance Measurement
As some USB-C tester enthusiasts know, ATorch released the model T3P a few months ago. which is an updated version of the model T3. I, and some others, suspected that the T3P replaced the T3 and ATorch would no longer release firmware updates for the original model T3. Today I discovered that ATorch released T3 firmware version 2.0.6 on 23-September. The version 2.0.6 firmware update is available on their support site at the link I attached to this post.
I had Google Gemini translate the v2.0.6 update notes.
Added 4-wire method line resistance detection & evaluation (requires pairing with a data line resistance adapter)
The voltage sampling circuit in the 4-wire method has virtually no current flowing through it, resulting in almost zero voltage drop across contact resistance. Therefore, the measured value reflects the true resistance of the cable itself.
I am about to order a T3P from AliExpress since the price in the ATorch Official Store recently dropped to $20.14 and I don't think its going to go any lower. I still cannot find the recently released ATorch cable resistance adapter on AliExpress, but I remain hopeful that it will appear soon.
