HT Instruments HT305 Manual De Instrucciones página 18

Accessory HT304k measures irradiance when connected to remote
unit SOLAR-02 and with Master instruments provided with 3-pole
HT connectors (PVCHECK, PVCHECKs, I-V400x, I-V500w, SOLAR I-
Vx) by means of an in-built monocrystalline cell and can be used on
MONOFACIAL modules.
•
Accessory HT304k CANNOT be connected to remote unit
SOLAR03, since it is provided of a 3-pole connector.
•
The backside of model HT304k reports the calibration constants of
the accessory (sensitivity) and the temperature coefficients to
compensate its effects (alpha) which must be set on the remote
unit SOLAR-02 or on the Master instruments provided with 3-
pole HT connectors (PVCHECK, PVCHECKs, I-V400x, I-V500w,
SOLAR I-Vx) to obtain correct irradiance values
