3.7 LUMINOUS INTENSITY MEASUREMENT
Push [cd] switch to enter cd mode in which Luminance intensity value appears.
(An example showing that the Luminance intensity is 338.0cd)
Luminous intensity＝C.C.F. × illuminance× L2
L：the distance from light source to the illuminance meter
If the distance data has not been entered, the distance data entry screen appears.
How to enter distance data
Push [cd] switch to enter cd mode.
Enter numerical value and push [SET] switch to activate the distance data.

Distance data you entered appears for 3 sec. and then, cd mode start.
・ Enter the distance data from 0.001 – 1000.
・ Error code E7 appears if you enter 0 as reference illuminance data.
・ Error code E3 appears if the calculated value is over the measurement range.
・ Push [cd] switch twice to reset distance data.
・ Distance data is deleted after turning off.
・ Distance data once you entered is saved till reenter the distance data or turning
