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 +(% style="color:#037691" %)**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 +(% style="color:#037691" %)**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 +**Steps:**
256 +
257 +1. (((
258 +**Calculate the K-value ratio**:
259 +
260 +Ratio=Desired Value
261 +)))
262 +1. Current Value=15002000=0.75Ratio=Current ValueDesired Value​=20001500​=0.75(((
263 +Multiply by the default K-value (1000) to get the new K-value:
264 +
265 +0.75×1000=750(Decimal)0.75×1000=750(Decimal)
266 +)))
267 +
268 +
269 +

271 +
272 +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.
273 +
274 +Modify the K value of sensor 2:
275 +
276 +* K value calculation as follows:
277 +* 1500/2000=0.75,  0.75*1000=750
278 +* Convert 750 to hexadecimal to 02EE.
279 +* Send command to sensor 2
