Illuminance vs Light Resistance
Measuring Conditions
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 (R10/R100)
log (100/10)
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.
Spectral Response

Light Resistance (kΩ)
Light Resistance:
measured at 10 lux with standard light A (2854k color
temperature) and 2h pre-illumination at 400-600 lux prior
to testing.
