www.kippzonen.com/dustiq
Needed before tare
1. Connected, working clean DustIQ 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, then consider adding
a third person, just to push the button.
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.

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

Value Meaning Remarks
There is not enough sun light and not enough
soiling on the sensors
Enough sunlight There is > 500 W/m² solar irradiation on the DustIQ.
But not (yet) enough soiling so wait for more soiling.
Enough soiling on both sensors There is >3% transmission loss in registers 21 and 25.
But not enough sunlight (yet).
0
2
Enough sunlight and soiling on both sensors.
Calibration possible.

Unstable soiled measurements Before calibration the DustIQ, must have had 2 minutes of stable sunlight
and the two sensors must have had 2 minutes of stable soiling.

1
On-site check for clear sky and local time is between 2 hours before and after local
solar noon. Check if there is >3% transmission loss in registers 21 and 25.
Contact people on-site to check readiness, time window and sky
conditions and if OK they can start the 2 minute waiting time
followed by pushing the button and cleaning.
Register 26 before calibration
Value Meaning Remarks
Successful calibration
Attempted to start without enough sun Calibration was halted. Nothing has been changed.
Register 26 should be checked before pushing the button.
Attempted to start without enough soiling Calibration was halted. Nothing has been changed.
Register 26 should be checked before pushing the button.

Attempted to start with
unstable sunlight on PV cell
Attempted to start with unstable dust measurement. On-site personnel touched the glass area of sensor 1 or 2 during the 2 minutes
before pushing the button.

1001
1002
1003
Button pushed but too short.
This prevents accidental start.
Push the button 3-5 seconds for the calibration to start.
1004
Time out. The button hasn’t been pushed
a second time within 2 minutes from first push.
Could be by accident. Not pushing the button a second time
is also a safe escape from the calibration procedure.
