What's wrong?

What is wrong with my configuration?

I get the following output from Recognition, which looks completely correct to me:

However, the determined results are not correct. I expect the PH value to be 7.1, but I always get 7.0.

Where is the error?

@SybexX What value should I set there? I have changed it to 0, but unfortunately it still doesn't work.

What happens if you remove the decimal shift?

[SybexX]

but: I don’t think it has anything to do with that, since the digits are being recognized correctly

Look at the third number in your last picture, the 5 is recognized as 3.1

Your image is a lot dark, increase the LED intensity.

In addition, you should move/adjust your ROIs so that your 7 is also recognized as a 7 and not as 6.9 ..........

@SybexX
i thought the interpretation was based on individual digits. and therefore the first digit 7.0 is interpreted as 7. the second is then 1.0 al 1

the first number consists of only two digits. so 7 and 1 should be interpreted as 7.1, shouldn't they?

but the value is still 7.0

These values ​​are calculated with a simple rounding and do not really say which value was really recognized.
In order to obtain more information, you should put the loglevel on debug, then you can see what was really recognized and what function the 1 down on a 0.

Since you have a digital display, the numbers should be recognized correctly so that the logic does not have to/cannot falsify the numbers too much(round down/round up).
