ECT-752 (EV Charging Cable Tester)

• Added on-screen keyboard so users can enter custom names and
  codes (Projects, Clients, Cables, etc.).
• Cable measurements are now locked after testing to protect
  results. Users can still unlock and edit them if needed.
• RCD measurement options expanded: now supports 10 mA, 20 mA,
  and 30 mA (previously only 30 mA).
• Added delay support for (Apriv) Škoda IV, Audi e-tron, and
  Porsche IC-CPD. These devices now power on in state A, even if
  they stopped due to an error.
• New warning shown if no Test Plans are available.
• Improved RTC accuracy.
• Added option to edit cables in the Master Test List.
• Corrected some German translations.
• On first boot, a language selection menu now appears.
• Added option to run Auto Measurement from a selected step.
• Bluetooth version check: warning is shown if outdated.
• Diode error now times out after 20 seconds if no user action
  is taken.
• VIN and Vehicle Type Plate fields added to Cable information.
• Main menu screen redesigned.

• Other Bug Fixes

• Bluetooth turns of when the user leaves Transfer mode
• Established mains socket power on at mains zero crossing to
  prevent nonsense tripping of F1 fuse.
• Fixed multiple minor bugs and improved overall system
  stability.

• Improved power up sequence to support the IC-CPD with extended
  power down time.

 
Bug Fixes

• Some general bug fixes

New Features & Enhancements

• Language Support: Added Spanish (SPA), Polish (POL), French (FRA), and Portuguese (POR).
• UI/UX: Extended QWERTY input to 35 characters and increased Testplan capacity to 200 slots.
• Keyboard: Added special character support for international layouts.
• Navigation: Testplans are now sorted alphabetically for quicker access.
• Visual Indicators: Added a “Powering off…” status message.
• False cable support: All the functions with powering on the IC-CPD don’t get blocked in case IC-CPD Control Pilot functionality is degraded.

Measurement & Performance

• Powering on Timing Optimization: Added an additional delay between powering on the cable and checking for State A to support slower-responding cables.
• Enhanced power down Logic: Implemented a 100ms State B transition between State C and A when powering off IC-CPD to support proper powering off sequence.

Bug Fixes & Compatibility

• EVSE Compatibility: Fixed communication and state issues specifically for Audi, VW, Opel, and BMW Flexible Fast Charger cables.
• False Warnings: Adjusted detection voltage after RCD measurements to prevent false warnings caused by ghost voltage.
• Logic Fixes: Corrected “FAIL” triggers for Control Pilot (CP) during Diode error, Error D, and specific State C scenarios.
• Timeouts: Resolved intermittent communication timeouts during RCDA testing in AUTO Mode 2.
• General: Fixed various translation errors across all supported languages and resolved an issue where data could get “stuck” when switching between testplans.
