Figure 1.2: Typical temperature dependency curve of the CM 4.
The CM 4 High Temperature Pyranometer is supplied with its own
individual graph of temperature dependence of sensitivity. Monitoring
the temperature during operation will allow easy data correction
afterwards for improved measurement accuracy. The table in
Appendix II lists how to interpret the Pt-100 output readings.
To guarantee long-term stability the CM 4 circuitry consists of high
temperature resistant components, such that continuous high
irradiance measurements have a minimum effect on the durability or
the stability of the instrument.
