Error Debugging

Often observed problems

Hardware failure

Camera not working --> check the interface, test another module
Low cost module with only 2MB of PSRAM instead of 4MB --> image taking will fail first. This will never work due to too low memory

ROI misaligned

This typically happens if you have suboptimal "Alignment Marks". A very simple and working solution is to put put higly contrasted stickers on your meter and put "Alignment Marks" on it (see picture below)

If after those adjustment you still have some issues, you can try to adjust your alignment settings in expert mode:

My Analog Meter are recognized as Digital Counter or vice versa

First, check that your ROI are correctly defined (yey!)
Second, verify that the name of your ROI analog and digital ROIs are different

Recognition is working well, but number aren't sorted correctly

You have to sort your ROI correctly (Bigger to smaller). Select your ROI and click either "move next" or "move previous". Repeat until your ROI are correctly sorted
