Advanced Settings
3.4.1 Calibration Settings
Go to Device -> Setting -> Calibration Settings of ToolBox App to enable calibration. EM310-UDL supports two calibration types:
- Numerical Calibration: users can define calibration values to correct every distance.
- Measure Outlier Calibration: users can define either outlier range or value. When the device distance value exceeds the outlier range (or value) compared to last value, the device will measure the distance again.
3.4.2 Threshold Settings
Go to Device -> Setting -> Threshold Settings of ToolBox App to enable the threshold settings and input the distance threshold. EM310-UDL will detect whether the distance reaches the threshold according to the collecting interval. If the threshold is triggered, it uploads the current data once instantly.
