  1. 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).
  2. 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.
  3. 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.
