Measurement Uncertainty over all,
according to GUM (Guide to the Expression of Uncertainty in Measurement), k = 2
Irradiance ±0.4 W/m² ± 1.6 % from rdg.
Irradiance IEC 61724-1, Class A
All Temperatures 1,0 K
User information
The sensor is designed for the measurement of solar irradiance (not concentrated) at PV monitoring. The
warranty is for 1 year from the date of invoice for the intended use. M&T does not accept any liability for
possible losses or damage due to incorrect usage of the sensor. Liability for consequential damages is excluded.
Special note: The housing for the Si sensors is not allowed to be opened by the installer or user, because as a
consequence, the housing will no longer be sealed after it is closed. If the housing is opened, the
manufacturer's warranty will be rendered void.
Maintenance
Scope of the regularly check (at least every 2 years): Cleaning of solar cell, external damage, mechanical
fastening, cable laying and any damage to the cable.
In the report IEA-PVPS T13-03: 2014 "Analytical Monitoring of Grid-connected Photovoltaic Systems" an
interval of 1 to 2 weeks is recommended.
Should damage be found that degrades the function or safety, the sensor is to be replaced.
A recalibration is recommended at least every 3 years.
