Measurement tolerances
Statement of accuracy in ± (% of reading + display error in counts (= number of smallest points)). 
The accuracy is valid for one year at a temperature of +23°C ± 5°C, and at a relative humidity of less than
75 %, non-condensing. Temperature coefficient: +0,1 x (specified accuracy)/1°C
