Calibration

| ** After saving the calibration value, the sensor will add the calibration value to the raw value and send the final value.
| If the current value exceeds the outlier range/values, the sensor will recollect the value.
Note:** This item is only for EM500-UDL.

Threshold and Alarm

the sensor will send current data ignoring the report interval.
**** Data Collecting Interval| The sensor will detect and check whether the value is triggered again after data collecting interval.
