1
One side of transformer secondary is connected to signal
common. Dedicated transformer is recommended.
2
Time for reaching 63% of reading at 25 °C and 1 m/s air-
flow.
3
Long term exposures to conditions outside normal range
or high humidity may temporarily offset the RH reading
(+3%RH after 60 hours).
4
15-30 VDC/24VAC power supply voltage required for
10 volt output.
