242 242  In the event of deviations in the sensor values, calibration can be carried out by modifying the sensor's internal parameter: K-value parameter(**Default: 03E8(H)=1000(D)**).

245 245  
246 246  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.

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.
255 +**Scenario:**
251 251  
252 -Modify the K value of sensor 2:
257 +* Sensor 1 (reference) reads 1500.
258 +* Sensor 2 reads 2000, but should match Sensor 1's value (~~1500).
253 253  
254 -* K value calculation as follows:
255 -* 1500/2000=0.75,  0.75*1000=750

257 -* Send command to sensor 2

280 +
281 +2. The default K-value 03E8 (1000) implies no scaling. Values below 03E8 reduce the output; values above increase it.
