(1) One side of transformer, secondary is connected to signal common. Dedicated transformer is recommended.
(2) Models with PM sensor included achieve ±5% accuracy over 0 to 80%RH range and an additional temperature shift of up +0.5° C.
(3) Time for reaching 63% of reading at 25° C and 1 m/s airflow.
(4) Long term exposures to conditions outside normal range at high humidity may temporarily offset the RH reading (+3%RH after 60 hours).
(5) Wiring with silicone or other high VOC insulation will affect TVOC readings.
