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 100 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.
