Operation via handheld terminal or PC with operating program: take minimum
communication resistance of 250 Ω into consideration.
Damping A damping affects all outputs (output signal, display). Damping can be enabled as follows:
• Via the onsite display, Bluetooth, handheld terminal or PC with operating program,
continuous from 0 to 999 seconds
• Factory setting: 1 s
