Measurement tolerances
Accuracy of measurement in ± (% of the reading (= rdg)+ tempera-
ture coefficient). The accuracy is valid for 1 year at a temperature of
+23°C +/5°C, and at a relative humidity of less than 80 %, non-con-
densing, and a colour temperature of up to 2856°K.
Temperature coefficiency: +/-0,5% every °C difference from the
given environmental temperature.
