You could do the calibration for the below reasons:
1. You have used it over 3 weeks without calibration;
2. The upmost accuracy is required
3. The meter been used in patically continual conditons.
And you could check the calibration steps as the video show, and here are some notice for you:
1. Please prepare YIERYI PH calibration power with 250ml of water at temperature of 25℃
2. Please wait till the value become stable, then press the "CAL" button, and press the button for about 3~5 seconds.
3. Please wait till the value flash become stable, then do the next calibration.

As you see, soil PH affect plant health a lot, if the PH is two low, then it could not take in the Nitrogen, phosphorous, potassium, sulphur, calicuim, magnesium, and molybdfenum, which will make the plant grow slowly, being small, and even withed, and rood rotten and death. And at too high PH, the soil cannot take in nitrogen, magnesium, iron, manganese, copper and zinc, which will make the plant have yellow leaves and inadequate nutrient and so on. So you see, the PH affect the plant growth a lot, and so do the temperature affect the plant to grow a lot also.
