|
|
<p>At first, for the most water meters the default configuration should be work. But the digit, especially the last digit differs in some devices.</p>
|
|
<h2 id="normal-transition">"Normal" transition</h2>
|
|
<p>In most cases, the transition of the last digit starts when the analogue pointer is > 9. </p>
|
|
<p>Often the last digit "hangs" a bit on this devices and comes not over zero. So it is not easy to see which digit is correct. In the first example 4 or still 3? (3 is correct).</p>

|
|
<h2 id="early-transition">Early transition</h2>
|
|
<p>Some units start the transition very early or run with the analogue pointer. In the third example, is it a 3 or a 2?</p>

|
|
<h2 id="inaccuracies-in-image-recognition">Inaccuracies in image recognition</h2>
|
|
<p>The models for image recognition are good, but have inaccuracies in the range +/- 0.2. In order to obtain as many correct results as possible, a treatment is carried out in the post process in the range of 9.8-0.2 for the analogue pointer, which must start differently depending on the type of counter.</p>

|
|
<p>If you have a devices with "normal" transition you should not have any issues. On devices with "early" transition, you can set the option <code>AnalogDigitalTransitionStart</code> to a value between 6 and 8.</p>
