Acquisition Method:
Level Crossing
The Level Crossing Acquisition Method acquires data each time the selected
master signal changes by a specific amount.
When you define a Level Crossing Acquisition Method, you must select the
master signal and define the level increment at which data is acquired.
Master Signal Selects a signal that determines when data is acquired.
Note When you select Time you get timed data acquisition, when you select
any of the feedback signals you get level-crossing data acquisition.
Level Increment Defines how much the signal must change before acquiring data. Initially a
default level increment is displayed, which for Time is 50 mSec, for Count is
1 segment, and for feedback signals such as Actuator Displacement is a
percentage of the signal’s full scale value. Type the desired level increment and
select appropriate units. The level increment must be greater than zero.
