Figure 4.13 Left: Trigger Acquisition. Right: No Further Action
Refer to Figure 4.13. The filter parameter sets a sample count. The sample count is a
period to measure if all of the values within these period of time exceed the trigger
level. If they are, this would allow trigger generation. If they aren't, no trigger would be
generated.
4.7 Operation Modes
There are three modes that could be run in the WISE-750. They are Datalogger, Fea -
ture Extraction, and Intelligent Mode respectively. You can set them in the WISE-750
Utility. They are independent modes. They each have their own functions respec -
tively. The function of each mode cannot be used in other modes. For example, the
Datalogger function in Datalogging mode cannot be used in Extraction Mode and
Intelligent Mode.
4.7.1 Datalogger Mode
The Datalogger Mode is hte default mode when first starting the application. No mat -
ter the final application is in Feature Extraction Mode or Intelligent Mode, this function
is always used in the starting stage of the application. After data logging, users can
analyze the data then understand the data features and will be able to set the criteria
afterwards. To use the datalogger, switch the utility to "Feature Extraction" Page.
Options and Parameters:

saves the data for.
File Count: The datalogger will save corresponded number of files according to this
parameter. For non-zero file count setting, the logger will save corresponded number
of files to the directory you set. For file count 0, the logger will save the files until you
press the stop button. The settings in different mode will result in different types of
data logging:
– Raw Data Mode: the datalogger will save data to file with the number of sec -
tion length data written in the file and save number of files for this parameter.
For example, if you set the section length for 2048 and file count for 100,
there will be 100 files saved and 2048 rows of data in each file.
– Feature Extraction Mode: the datalogger will save feature data (calculated in
every iteration of section length) to file with 100 rows of feature data in each
file. The file count sets the number of files to be saved.
Destination: set the data logger directory in this PC.
Configuration Process:
1. Select the data logging types. The option "Feature Values" will save the feature
values to the destination you set.
