Solve Hard-to-Troubleshoot Temperature Related Problems
With the Temperature Plugin, you can:
- Check and Test Key Sensors: Read live data for the Shutter, CMOS Unit, and Main Board.
- Eliminate Guesswork: Spot failed or drifting temperature sensors instantly without replacing good parts.
- Target the Root Cause: Match fault codes directly to faulty sensor boards.
- Save Bench Time: Cut down diagnostic time and avoid frustrating callbacks.
Common temperature-related problems:
- Soft Focus on Hot Days: Caused by heat expansion shifting the Lens Flange / CMOS sensor distance.
- Random Overexposure or Underexposure: Caused by current fluctuations in the AE system.
- Dark Images at High Shutter Speeds: Caused by temperature shifts in the shutter timing.
- Flash Malfunctions: Caused by thermal drift in the flash control unit.

Image 1 (Error History Tab): Displays Error 351 — Possible cause: Faulty CMOS Sensor Unit.
Image 2 (Temperature Reading Tab): Shows real-time sensor readings against normal room temperature (23°C):

- Normal Benchmark: 23°C
- CMOS Unit: 27°C (Elevated)
- Main Board 2: 31°C (Overheating / Over-range)
The live data pinpoints the thermal failure immediately, confirming the exact board causing the Error 351 shutdown.
