Definition of exponential function :
x(t) = log (-Bt)
Definition of exponential factor X :
X = log (-Bt) at t = T, where T is the length of the time block.
Actually X is the attenuation rate of the exponential window at the end of the
time block. This should be a real number between 0 and 1.
Channel ID : Select type of channel ID from Model/ODS and Machine.
Channel ID for modal testing or ODS testing.
Point number: Enter a value between 0 and 999.
Direction
: You can select one of the directions from a pull-down menu.
+X, -X, +Y, -Y, +Z, -Z, +R, -R, +T, -T, +P, -P. These point ID’s and direction
labels are used for modal or ODS testing work. The point ID’s will be stored
in the data file for identifying the points.
Auto Advance
: ON/OFF: Auto advance is a feature that is useful for taking
many data points. If you have auto advance turned on, then you can assign an
advance number after you save the data file. Each channel is independent of
each other, so you can auto advance only the channels you wish to advance.
Advance Number
: Advances the number of Channel ID after you save the
file.
