Assuming the reported original Distance value is 1000mm, the Calibration is reduced by 100mm
，
and the reported value is
900mm
SetGlobalCalibrateReq
：
Calibration is reduced by 100mm

Clear the calibration value: the reported value is restored to 1000mm

Downlink: 0300000000000000000000
Device returns: 8300000000000000000000
Note:
1. When Multiplier is not 1, Calibration value = DeltValue*Multiplier.
2. When Divisor is not 1, Calibration value = DeltValue/Divisor.
3. This universal calibration supports calibration of positive and negative numbers.
4. Negative values use the 2's complement
5.6 Example for MinTime/MaxTime logic
Example#1
based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V

REPORTS 3.6V REPORTS 3.5V REPORTS 3.6V
Note:
MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BatteryVoltageChange value.
