Dark current of S9295 at –20degC, stdv=62mV confirmed

At equivalent 5000PLC, it can be read 4.2 min/reading is optimum in term of noise reduction.

At >100mV range, 50Hz, where 100LPC->0.25read/s, digital filter for 50 reads (MED) corresponds 200s=3.3min>>20s. But in 10mV range, where 17 read/s, the 50 reads corresponds to 50/17=3s <<20s
