Mengting Qiu 81.4 244 **Calibration Principle**
kai 80.1 245
Mengting Qiu 81.4 246 The K-value scales the sensor's output. If multiple sensors measure the same parameter but show different values, adjust the K-value of the secondary sensor(s) to match the primary sensor's reading.
247
248 **Step-by-Step Example**
249
kai 80.1 250 if the value of sensor 1 is 1500 and the value of sensor 2 is 2000, it is necessary to keep the values around 1500if the value of sensor 1 is 1500 and the value of sensor 2 is 2000, it is necessary to keep the values around 1500.
251
252 Modify the K value of sensor 2:
253
254 * K value calculation as follows:
255 * 1500/2000=0.75,  0.75*1000=750
256 * Convert 750 to hexadecimal to 02EE.
257 * Send command to sensor 2
