Velocity Channels
The following sections will describe how to test alarms, verify channels, verify
filter corner frequencies, and test OK limits for channels configured as Velocity.
The output values and alarm setpoints are verified by varying the input signal
level and observing that the correct results are reported in the Verification screen
on the test computer.
Velocity channels can be configured for the following channel values and alarms:
