- Perform a Factory Reset: Go to
Utility → System → Factory Reset (or press and hold the “Run/Stop” button while turning on the scope – test this combo).
- Re-calibrate the Touchscreen: Navigate to
Utility → Touch Calibration. Use a stylus or the tip of a pen (not your finger) to hit the crosshairs precisely.
- Update the FPGA Logic (Separate File): Some HDS2102S firmware updates require a secondary file for the waveform generator. Check OWON’s download page for a file named
fpga_update.upk. Apply it using the same USB method, but with the scope already booted.
What You Will Need:
- A Windows PC (7/10/11, for formatting and file copying).
- A USB 2.0 flash drive, 8GB or less (Kingston, SanDisk Ultra Fit USB 2.0 often works best).
- The correct firmware file from OWON (we’ll discuss where to find the stable version).
- A micro-USB cable (optional, for serial debugging if the screen is completely dead, but we cover screen-based recovery first).
