Measuring device for synchronous recording of measurement values of up to three additional reference cells

Recording of up to three additional reference cells for spectral verification

The PSL REF is used to record data for up to three reference cells. This is most often used to record irradiance in different spectral regions. The measurement is synchronized with the power measurement performed by the tester measuring load.


Product Specification

› Three inputs for reference cells
› Three standard filtered reference cells for
VIS, NIR and IR optional
› Optional customized filtered reference cells available
› Works as a slave unit in conjunction with the
tester measuring load
› Includes software upgrade for full integration
into the solar simulator
› Can also be cascaded for recording more
reference channels
