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)**).

244 -**Calibration Principle**
244 +(% style="color:#037691" %)**Calibration Principle**
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.
247 247  
248 -**Step-by-Step Example**
248 +(% style="color:#037691" %)**Step-by-Step Example:**
249 249  
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.
250 +**Scenario:**
251 251  
252 -Modify the K value of sensor 2:
252 +* Sensor 1 (reference) reads 1500.
253 +* 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
256 -* Convert 750 to hexadecimal to 02EE.
257 -* Send command to sensor 2
258 -* Send：0B 06 00 53 02 EE F8 5D  Send successfully and return this command
255 +**Steps:**
259 259  
257 +**~1. Calculate the K-value ratio**:
260 260  
259 +Ratio=Desired Value/Current Value=1500/2000=0.75
261 261  
261 +Multiply by the default K-value (1000) to get the new K-value: 0.75×1000=750(Decimal)
262 262  
263 +**2. Convert the (% style="color:#037691" %)new K-value(%%) to hexadecimal**:
264 +
265 +* 750(D) = 0x02EE(H)
266 +
267 +**3. Send the calibration command to Sensor 2**:
268 +
269 +* Command Format: **0B 06 00 53 [(% style="color:#037691" %)K-value(%%) (2 bytes)] [CRC]**
270 +* Example for K-value 0x02EE: 0B 06 00 53 02 EE F8 5D

272 +(% style="color:red" %)**Notes:**
273 +
274 +~1. Always use the sensor with the most trusted reading as the reference (do not modify its K-value).
275 +
276 +2. The default K-value 03E8 (1000) implies no scaling. Values below 03E8 reduce the output; values above increase it.
277 +
278 +3. CRC is auto-generated by the tool (no manual calculation needed).
