Recording and evaluation

All data on the lighting installation (see section "Measurement conditions") must be recorded in drawings, photos and descriptions, along with measuring instruments and measurement execution. Measuring values are documented in tables, graphics, photos or digital storage and screen display.

From the measured illuminance values, minimum and maximum illuminance Emin and Emax can be determined as well as average illuminance Ē and uniformity of the illuminance values g1 and g2, n being the number of measuring values and Ei the respective individual measuring value.

g1 = Emin/Ē
g2 = Emin/Emax
