The gradient Glog should be calculated using the mathematical expression: Glog = log10 I(D) log10 I(D+0.1). Where I is th
11、e measured candela value and D is the vertical angular position in degrees. Plot the results Glog vs. D.5.2.5.2 Gradient Position in the Beam PatternThe lamp aim shall be adjusted until the vertical angular position at which the maximum gradient measured along the V-Vline is located at 0.75 degree d
