3.2.10.7 Environmental Conditions
Use the transmitter only within the temperature range of -10 °C…+40 °C. Avoid the inadmissible exposure of
heat, cold, direct sunlight, UV radiation or vibration. Install the instrument in that way, that air circulation is
possible and heat sources are sufficient far away.
