Page 3: Introduction
The DustVue is designed to be the principle component of an independent soiling measurement station, or as an add-on peripheral to any new or existing meteorological station. The DustVue is delivered field ready and requires no programming. The DustVue will work with any photovoltaic (PV) panel up to 700 W. -
Page 4: Initial Inspection
CR310 Certificate of Calibration 8 GB USB flash drive with Device Configuration Utility software Upon receipt of the DustVue, inspect the packaging and contents for damage. File damage claims with the shipping company. Immediately check package contents. Thoroughly check all packaging material for product components that may be concealed. - Page 5 5. Set time. Although set at the factory, confirm time settings are correct and if necessary, reset the clock at the time of deployment. a. In the Logger Control tab use the drop down next to Reference Clock Setting and select UTC (Greenwich Mean Time). Click Set Clock to apply the setting. DustVue...

4.2 User entered values UserEntered values will be applied at the factory prior to shipping if they are provided to Campbell Scientific when the DustVue is ordered. Confirm all UserEntered values are entered correctly at the time of deployment. CAUTION: Be sure to check the Longitude_UserEntered, TempCoefflscTest_UserEntered, TempCoefflscRef_ UserEntered, IscTeststc_UserEntered, and IscRefstc_UserEntered values. -

Page 14: Operation
Descriptions of available values are shown in Variable description (p. 15) In accordance with IEC 61724-1 (2021), the DustVue calculates the daily soiling loss index during the hour before and the hour after solar noon. Only the values showing effective irradiance greater than 500 W/m are included to minimize the effects from the zenith angle of the sun, PV panel current dependence on irradiance level, and air mass density. -
Page 15: Offset Correction
3. Results will be available when the minimum number of data points has been met for calculating a good offset value. This is typically midnight if the offset was initiated in the morning, or midnight of the following day if the offset was initiated in the afternoon or evening. DustVue... -
Page 16: Maintenance
If the maintenance button is inadvertently pressed for more than 5 s and the offset correction is not needed, the process can be aborted by accessing the DustVue through the assigned IP address and using Device Configuration Utility to reset the Offset Correction variable to 0 before midnight. -
