240 +== 4.6 Calibration Values (K-value Adjustment) ==
241 +
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)**).
243 +
244 +**Calibration Principle**
245 +
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 +
250 +Scenario:
251 +
252 +* Sensor 1 (reference) reads 1500.
253 +* Sensor 2 reads 2000, but should match Sensor 1's value (~~1500).
254 +
255 +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.
256 +
257 +Modify the K value of sensor 2:
258 +
259 +* K value calculation as follows:
260 +* 1500/2000=0.75,  0.75*1000=750
261 +* Convert 750 to hexadecimal to 02EE.
262 +* Send command to sensor 2
263 +* Send：0B 06 00 53 02 EE F8 5D  Send successfully and return this command
