Measuring tolerances
Indication of accuracy in ± (% of reading + display error in Kelvin
"K") "K" for Kelvin stands as absolute value of a temperature diffe-
rence or deviation.
Accuracy for the period of one year at a temperature of +23°C ±5K,
at a relative air humidity of less than
80 %, non-condensing. The warm-up time is 1 minute.
