Advanced Settings

Data Collection Settings

Go to “Device Settings- >Basic” of ToolBox software or “Device - > Settings -> Data Collection Settings” of ToolBox App to select the data you need to monitor. This feature is only supported by EM500-CO2 and EM500-SMTC sensors.

Calibration Settings

Numerical Calibration:
The toolBox supports numerical calibration for all items. Go to “Device Settings - > Basic” of ToolBox software or “Device - > Settings -> Calibration Settings” of ToolBox App to type the calibration value and save, the device will add the calibration value to the raw value.

CO2 Calibration:
For EM500-CO2, ToolBox provides more calibration methods:
Manual Calibration: Put the device in an open outdoor environment for more than 10 minutes and click this button to calibrate the CO2 value.
Factory Calibration Restored: Clean the manual calibration and turn it back to factory calibration.

Abnormal Value Prevention:
For EM500-PT100/SWL/UDL, ToolBox provides an abnormal value prevention feature for accurate results. If the current value exceeds the range of the previous value, the sensor will discard the current value and remeasure it again. Take 20% as an example, if the last value is 5 and the max range is 10, the next value should be within the range 3-7, or the sensor will measure again.
