3.3 Recommended Operating Conditions
Humidity and temperature:
The sensor shows best performance when operated within the normal operating conditions (dark green
area in Figure 5). This means 20…80 %RH, temperature >0 °C and dew point temperature <60 °C.
Exposure conditions outside this “Normal operating condition” for a long time, especially at high humidity
>80 %RH may cause a temporary humidity gain error. If the sensor is brought back to normal operating
conditions, the initial values will recover. Applications with high humidity at high temperatures will result in
slower recovery. Reconditioning procedures can accelerate the recovery process.
Although the sensors would not fail beyond the normal operating condition limits, the specification is
guaranteed within the “Normal operating condition” or within the “Extended operating conditions” (light
green area) after a reconditioning procedure.
Prolonged exposure to extreme operating conditions (marked orange in Figure 5) may accelerate ageing.

Normal operating conditions (humidity = 20…80 %RH & T > 0 °C & Td < 60 °C)
Extended operating conditions (outside of normal operating conditions & Td < 80 °C)
These values for humidity over water are physically not possible at negative temperatures
Humidity accuracy not specified due to working point (Td > 80 °C)
These humidity values are physically not possible at normal pressure (Td > 100 °C)
