FAQ

• Calibration

  • How often do I need to execute local calibration?

    • Only once. The calibration is valid for the whole lifetime of the device.

  • What is the calibration frequency with respect to the lifetime of the DustIQ?

    • It is needed only once to make sure the effect of your local dust is used to get the best measurements.

  • What is the calibration frequency of the DustIQ (mainly the LED)?

    • The DustIQ does not need recalibration for at least 5-10 years as it has extra internal sensors and compensation for any potential wear or drift.

  • Is it necessary to send to a K&Z facility for calibration?

    • No. All components have been selected in such a way that we do not anticipate factory recalibration. A local dust calibration also measures and corrects for any future deviation from the original factory calibration.

  • Is the DustIQ able to calculate loss when covered with dust different to the calibration dust sample?

    • The DustIQ works with dust it has been calibrated with. For the factory calibration it is Arizona Test Dust. For other dust types, the DustIQ can be calibrated locally, it cannot be calculated or "programmed".

  • Since it is needed to do calibration with natural soiling, is the data still valid before calibration?

    • The data will be less accurate most likely. After local dust calibration the "old" data can be post-processed as described in the manual.

  • What to do in case of a dust storm where the local dust is different?

    • Ideally, perform a local dust calibration soon after and record the mentioned Modbus registers for dust slopes before and after. Going back to factory settings is possible.

  • Can you provide more details about the on-site calibration? How long does this take, how much labor is required, etc.?
