240 +== 4.6 Calibration Values (K-value Adjustment) ==
241 +
242 +When sensor readings show deviations, calibration can be performed by modifying the K-value parameter in the sensor: K-value parameter(**Default: 03E8(h)=1000(D)**).
243 +
244 +For example：
245 +
246 +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.
247 +
248 +Modify the K value of sensor 2:
249 +
250 +* K value calculation as follows:
251 +* 1500/2000=0.75,  0.75*1000=750
252 +* Convert 750 to hexadecimal to 02EE.
253 +* Send command to sensor 2
254 +* Send：0B 06 00 53 02 EE F8 5D  Send successfully and return this command
