NOTE:

 

 

 

 

 

 

 

For all Start Trigger types, the device must be armed

Data storage and display will not begin until the device triggers.

Data Tab

Figure 4-16. Data Tab

To save data to a file on the PC, select the Data tab and choose a filename. This data can be saved in Binary or Delimited (.csv) format.

Binary format is faster, and is recommended for slower PCs. Binary format also creates files that are about 50% smaller than Delimited files. Binary files can be converted to “.csv” format later by selecting Tools --> Export Data File.

Delimited format can use either commas or tabs as the delimiter, and the time can be saved as Elapsed Time or as a Date/Time stamp.

There are three “Save Behavior” options:

 

FIG 4-17. Data ‘Save Behavior’ Options

 

 

Auto-overwrite

If a file with the same name already exists, it will be automatically overwritten when

 

the Start Acquisition button is pressed.

 

 

Prompt for

If a file with the same name already exists, a prompt

overwrite

will appear when the Start Acquisition button is pressed.

 

 

Add creation

A timestamp is added to the filename, in the format

time to

YYYY-MM-DD-hhmm-ss. For example, MyFile.bin

filename

becomes MyFile-2011-1031-1121-03.bin. The timestamp will be automatically added

 

every time the Start Acquisition button is pressed, so multiple acquisitions can be easily

 

stored to the same folder without revisiting the Device Configuration window.

 

 

Data Displays

 

From the Main Window, you can choose to view live data from any combination of Gauges, Bars,

 

Digital Displays, Tables, and Waveforms. These displays can be opened by clicking the appropriate

 

button in the Main Window.
