15.3 Specifications
15.3.1 Accuracy
■
Specified accuracy ± (% of the reading + display error in counts).
■
Accuracy is maintained for 1 year at +23 °C (± 5 °C), ≤75 % RH (non-con-
densing).
■
Temperature coefficient: +0.1 x (specified accuracy) / 1 °C.
■
To avoid impaired measurements, do not operate the product in areas with
electromagnetic field strengths >1 V/m (±5 %).
