Page 12: Condensation Guard (Cg) Against Temporary Condensation
User Manual HTS801 3.4.3. Condensation Guard (CG) against Temporary Condensation Temporary condensation on the sensing element in highly humid environments is eliminated when a specified RH set point (factory setting: acc. to order code) is reached. By intensive heating of the sensing element for 10 seconds occurring dew is evaporated. -
Page 13: High Humidity Guard
The dual heating system of the HTS801 prevents both: condensation on the RH sensing element and on the probe body by a regulated heating strategy. This leads to very short response time and fast recovery after condensing conditions. - Page 14 User Manual HTS801 CONFIGURATION HINT Display alarms can be configured via display and push-buttons only.
