BEFORE CALIBRATION
www.kippzonen.com/dustiq
Needed before calibration
1. Connected, working, soiled DustIQ (3% transmission loss) with software version 2.15 or higher
2. DustIQ must be operative for minimal 3 minutes
3. Modbus registers 20-40 must be read and logged for soiling ratio’s, transmission losses, status flags,
dust slopes etc. (see manual section 4.2)
4. A person on-site and a remote person reading DustIQ data and the manual .
5. If moving from the back of the DustIQ to the front takes more than 20 seconds, than consider adding
a third person, just to push the button.
6. A clear sunny sky
The sky must be free of clouds and airplane contrails for at least 10 minutes.
The DustIQ calibration button must be pressed a second time within 2 minutes of the first push. The time available for
cleaning and drying is therefore 2 minutes. Otherwise the calibration procedure will stop, nothing will change and normal
operation will resume.
For local dust calibration it is strongly advised to take close up pictures of the PV modules nearby, DustIQ sensors and
PV cell before and after cleaning. This to help identify possible errors that might be made during the calibration.
DustIQ LED light interpretation
Regular operation, 5 seconds of blue led light with a 60 second interval
Feedback during the Tare or field calibration are given by the 2 sensors and the calibration button. There are 2 cases:
1. Slow blinking is 1x per second, confirmation and DustIQ awaiting next input
2. Fast blinking is 10x per second, this is the error signal
for further information see error code in register 27
Both signals last 30 seconds in total, before normal operation restarts.

Local Check
Check for clear sky and no clouds.
Inform person of start of calibration when OK.
Do not cast a shadow on the DustIQ during the calibration process!
No action needed.
Push calibration button for 3 seconds
No action needed.
Check sensors or button flash
Slow blinking = proceed with next step
Fast blinking = stop and inform person
During calibration 0 will be presented in register 27.
If an error occurs register 27 is updated with a specific code. (manual section 4.2.2)
Clean and dry the whole DustIQ front
No action needed.
Push button again (for 3 sec.)
No action needed.
Wait
Sensors and button light up continuously for 1 minute
Do not cast a shadow on the DustIQ
Do not touch the DustIQ
Check sensors or button
Slow blinking = OK and finished
Inform person of successful completion
Fast blinking = error
Inform person
Confirm successful calibration in register 27 (manual section 4.2.2).
and optionally read and use new dust slopes. (manual section 4.1).
If unsuccessful read error code in register 27 for possible reasons and solutions.
On-Site
1
Check register 26 for enough soiling and sun and inform on-site person 1.
(the expected value is 3), for further details check the cheat sheet.
