The final OUTCOME can be:
 Non-displayable: if the obtained values are inconsistent (e.g. PRp >1.15) or if
irradiation has never reached a steady value > minimum threshold set.
 The maximum performance point (PRp) of the system
The highest performance (maximum value of PRp) is detected according with previous
relationships.
10.2. RECORDING ON PV SYSTEMS
As regards the recordings which can be carried out by the instrument on PV installations
by pressing the GO/STOP key, the same relationships described in § 10.1 above apply,
with the only difference lying in the condition of “steady irradiation” for the samples
detected with PI defined by the user. In particular, the following conditions must exist in
order to obtain a positive result:
 The AVERAGE value of the measured irradiation is > minimum threshold set (see §
5.3.3.3)
 For recordings with PI < 1min the difference between the maximum and minimum
measured irradiation values is < 20W/m
2
 For recordings with PI > 1min the AVERAGE value of the measured irradiation is
always > minimum threshold set (see § 5.3.3.3)
