Compensation Matrix
Name Names the matrix used by the ALC compensator.
ALC matrix files are saved in the Specimen directory. The default ALC matrix
file is default.mat. If you want to use an existing matrix, copy the mat file into
the Specimen directory, and then type the matrix file name in the
Compensation Matrix Name box.
Initial Gain Specifies the amount of initial gain applied to the signal. The default is 100%,
or no magnification.
Enable Frequency
Compensation Attempts to run the test at a faster rate than specified in the selected profile.
For example, if the profile specifies that the end levels be achieved using a
frequency of 0.2 Hz, the application may actually achieve these end levels at
0.5 Hz. The maximum rate increase is specified on the ALC tab in the
Compensators tab in the Station Setup window in Station Manager.
Note This option is available only if you have specified a single-channel
profile.
Verify Loaded Matrix
Parameters Specifies whether you want the application to compare the matrix parameters
entered on this Matrix window with the parameters currently loaded in the
controller’s real-time.
If you choose “No, Use Loaded Parameters.” the application will disregard
any file saved on disk that matches the entered name and use the matrix
parameters currently loaded in the controller’s real-time.
If you choose ”Yes, Reload if No Match.” the application will compare the
matrix parameters entered in this Matrix window with the parameters currently
loaded in the controller’s real-time. If the parameters do not match, the
application will redefine the real-time matrix using the parameters currently
entered in this Matrix window. In this case the application will also compare
the entered parameters with those stored in any file in the current Specimen
directory that uses the entered name. If they match, the matrix values from the
disk file will be down-loaded into the real-time matrix. If not, the real-time
matrix values will be reset to indicate no correction values are present.
To use a saved compensation matrix for the current test, you must copy (using
Windows operating software) the desired matrix file into the current Specimen
directory before you enter the desired matrix name (as it appears in the
Specimen directory) and definition parameters in this window. If the name or
other parameters do not match precisely, or if the desired matrix does not exist
in the current Specimen directory, the application will create a new real-time
matrix with the entered name.
