Description Specify typical rate of change for the interface position.
Selection • Fast > 1 m (40 in)/min
• Standard < 1 m (40in) /min
• Medium < 10 cm (4in) /min
• Slow < 1 cm (0.4in) /min
• No filter / test
Factory setting Standard < 1 m (40in) /min
Additional information The device adjusts the signal evaluation filters and the damping of the output signal to the
typical rate of level change defined in this parameter:
Process property Step response time / s
Fast > 1 m (40 in)/min 5
Standard < 1 m (40in) /min 15
Medium < 10 cm (4in) /min 40
Slow < 1 cm (0.4in) /min 74
No filter / test 2.2
DC value lower medium
Navigation Setup → Advanced setup → Interface → DC lower medium
Prerequisite Operating mode (→ 159) = Interface or Interface with capacitance
Description Specify the relative dielectric ocnstant ε
r
of the lower medium.
User entry 1 to 100
Factory setting 80.0
Additional information For dielectric constants (DC values) of many media commonly used in various
industries refer to:
• the Endress+Hauser DC manual (CP01076F)
• the Endress+Hauser "DC Values App" (available for Android and iOS)
The factory setting, ε
r
= 80, is valid for water at 20 °C (68 °F).
