Damping

Damping affects all the outputs (output signal, display) and is only available in the
continuous 4 to 20 mA mode.
Damping has no effect on the SIO.
Activating damping:
Via local display, Bluetooth, handheld terminal or PC with operating program, continuous
from 0 to 999 s
Factory setting: 1 s

Switch output

Preset switching delay times can be ordered:
• 0.5 s when the tuning fork is covered and 1.0 s when the tuning fork is uncovered
(factory setting)
• 0.25 s when the tuning fork is covered and 0.25 s when the tuning fork is uncovered
(fastest setting)
• 1.5 s when the tuning fork is covered and 1.5 s when the tuning fork is uncovered
• 5.0 s when the tuning fork is covered and 5.0 s when the tuning fork is uncovered
The user can also set the switching delays for when the fork is covered and uncovered
in the range from 1 to 60 seconds independently of one another.
(Operation via display, Bluetooth or FieldCare, DeviceCare, AMS, PDM)
