- One side of transformer, secondary is connected to signal common. Dedicated transformer is recommended.
- Time for reaching 63% of reading at 25° C and 1 m/s airflow.
- Long term exposures to conditions outside normal range at high humidity may temporarily offset the RH reading (+3%RH after 60 hours).
- 15-30VDC/24VAC power supply voltage required for 10 volt output.
