4. In the case of Monofacial modules, the Fig. 34 screen is present on the display. The
following parameters are shown:
➢ VPN voltage between positive and negative pole of the string
➢ Module temperature (with PT305 probe connected)
➢ Module irradiance measured by reference cell HT305
➢ Display of currently selected PV module
➢ References of C1, P1, C2, P2 terminals connected to the instrument

5. In the case of Bifacial modules, the screenFig. 34 is present on the display. The
following parameters are shown:
➢ VPN voltage between positive and negative pole of the string
➢ Module temperature (with PT305 probe connected)
➢ Irradiance of the front side of the module measured by reference cell HT305
➢ Irradiance of the back side of the module measured by reference cells HT305
The "Rear Irradiance” parameter indicates the minimum value between the
irradiance measured by the HT305 cells at the bottom back (BB) and top back
(BT) of the module
➢ Display of currently selected PV module
➢ References of C1, P1, C2, P2 terminals connected to the instrument
