A measurement map calculates the average and uniformity of point illuminance readings taken across a space with a lux meter — the U0 = Emin/Eaverage ratio defined by EN 12464-1 is one of the acceptance criteria for a lighting design. This tool instantly calculates average, minimum, maximum and U0 from the grid of readings you enter, letting you quickly verify compliance during a site survey or in a handover report.
