11. **Accuracy calculation**

165

166

Within the working temperature range, when the temperature change rate is less than 0.3°C/min, the accuracy of this product = ADC sampling accuracy + line resistance error + contact impedance error. According to the measure principle, it is necessary to wait for the module to be powered on for 45 minutes before measuring.
