Measuring Conditions
1. Light Resistance:
measured at 10 lux with standard light A (2854k color
temperature) and 2h pre-illumination at 400-600 lux prior
to testing.
2. Dark Resistance:
measured 10 seconds after pulsed 10 lux.
3. Gamma Characteristic:
between 10 lux and 100 lux and given by
log (R10/R100)
T = log (100/10)
– log (R10/R100)
R10, R100 cell resistance at 10 lux and 100 lux.
The error of T is +0.1.
4. Pmax:
Max. power dissipation at ambient temperature of 25°C.
5. Vmax:
Max. voltage in darkness that may be applied to the cell
continuously.
