Specifications and Reference Data
Humidity limits
0–100% relative humidity.
Turn-on Time
Process variables will be within specifications less than 60 seconds
after power is applied to transmitter.
Damping
Response to step input change can be user-selectable from 0 to 7
seconds for one time constant. This is in addition to sensor response
time of 0.2 seconds.
