Before beginning the firmware installation, prepare your workspace to minimize the risk of bricking your device: 2 in 1 Pocket Oscilloscope - Fnirsi DSO-TC2 fnirsi dsotc2 firmware

Correcting language translation errors and improving menu navigation speed. Prerequisites for the Firmware Update

Ensure your cable transfers data. Many cheap USB-C cables only provide power charging and will not recognize the device on your PC.

Always double-check the model number on the screen of the device or in its system information before proceeding with an update. Ensure you are using a , not just a charging cable

If the update fails immediately, double-check that you haven't accidentally downloaded the firmware for the TC1 or TC3 .

: We provide a patched firmware version (available on GitHub [anonymized for review]) that:

Not from the probe. From the device itself. A low, rhythmic beep, twice per second, like a sonar ping. And on the screen, a third channel appeared—‘Else’. Its waveform was a smooth, perfect sine wave, but its frequency was 3.14159… kHz. Pi. Exactly Pi. Always double-check the model number on the screen

The FNirsi DSO-TC2 firmware is based on the STM32 microcontroller and provides a range of features, including:

Understanding the firmware is crucial for:

FNIRSI DSO-TC2 is a popular 2-in-1 tool that combines a digital oscilloscope with a transistor tester. Keeping its firmware up to date is essential for ensuring accurate measurements and accessing improved features like faster waveform auto-scaling and enhanced component identification. Latest Official Firmware Features The DSO-TC2 firmware manages two distinct modes: Transistor Tester Mode

During the upgrade, the DSO-TC2's screen will provide clear feedback. Do not disconnect the USB cable or interrupt the process. After the upgrade, the device will restart. The next time you power it on, the splash screen should display the new firmware version numbers.

Transistor tester algorithms are continuously refined. Newer firmware provides more accurate readings for ESR (Equivalent Series Resistance), diode forward voltage, and capacitor leakage.
