Temperature correction factor
When the instrument is used under the following environmental conditions:
0°C-18°C, ≤80%RH; 28°C-40°C, ≤80%RH
Measurement Accuracy: Multiply the basic measurement accuracy value listed in chapter 5.3.1 to
5.3.4 by the temperature correction factor K in the following table:
