5.2. PROGRAMMING THE REMOTE UNIT SOLAR-02
In order to obtain correct irradiation measurement results, it is necessary to carry out a
correct preliminary setting of the sensitivity values of the probes connected to the PYRA/
CELL input of the unit. The set values will be read and considered by the master
instruments upon testing/recording and will be kept by the SOLAR-02 even when the unit
is turned off, until they are modified.
The unit SOLAR-02 allows setting the parameters of max 3 irradiation sensors. In detail:
➢
The use of a sensor type Irr-S2 requires setting the sensitivity (K) expressed in mV/
kW*m
-2
or in µV/W*m
-2
and the parameter Alpha expressed in %/°C for the various types of
silicon (monocrystalline, polycristalline, etc.)
➢
The use of a sensor type Irr-P requires setting the sensitivity (K) expressed in mV/
kW*m
-2
or in µV/W*m
-2
. The parameter Alpha expressed in %/°C is ignored.
The presence of “K” symbol on the left of “Tc” temperature value,
indicates that the Cell temperature (Tc) value displayed is not a measured
value buti s a calculated value according with previous relationship.
When the SOLAR-02 is switched on (before connection to MASTER
instrument) the Tc value is the measured value.
