80.1	241
81.4	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)).
80.1	243
81.6	244	(% style="color:#037691" %)Calibration Principle
80.1	245
81.4	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
81.6	248	(% style="color:#037691" %)Step-by-Step Example:
81.4	249
81.6	250	Scenario:
81.5	251
	252	* Sensor 1 (reference) reads 1500.
	253	* Sensor 2 reads 2000, but should match Sensor 1's value (~~1500).
	254
81.6	255	Steps:
	256
81.10	257	~1. Calculate the K-value ratio:
81.7	258
81.9	259	Ratio=Desired Value/Current Value=1500/2000=0.75
81.7	260
81.10	261	Multiply by the default K-value (1000) to get the new K-value: 0.75×1000=750(Decimal)
81.7	262
81.16	263	2. Convert the (% style="color:#037691" %)S(%%)new K-value to hexadecimal:
81.7	264
81.14	265	* 750(D) = 0x02EE(H)
81.9	266
81.15	267	3. Send the calibration command to Sensor 2:

81.16	272
	273
80.1	274	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.
	275
	276	Modify the K value of sensor 2:
	277
	278	* K value calculation as follows:
	279	* 1500/2000=0.75, 0.75*1000=750
	280	* Convert 750 to hexadecimal to 02EE.
