- Setpoint Range RH: 10-80% RH in 1% increments; Temp: Minimum to Full Scale in 1°F increments
* Specified accuracy with 24VDC supplied power with rising humidity**Reset Rate is time required to recover to 50% RH after exposure to 90% RH for 24 hoursOne side of transformer secondary is connected to signal common, so an isolation transformer or dedicated power supply may be required.
