5. The “System Status” on main screen will indicate “Logging Data” and display the selected
“Sampling Interval” and "Gold IDE Setup".
Suspending Operation (Pause Data Logging)
1. Refer to “Establishing Communication” above for connection to computer
2. Select “Pause Data Logging” to suspend operation.
3. On the main screen, verify that the “System Status” displays the message “Not Logging Data”.
Data File Format
Data files are stored to the computer using a comma-separated values (.csv) file format. These files can
be imported by standard data handling software (e.g., Microsoft Excel, MATLAB, etc.). The data file
column headers and brief descriptions are given below (Table 1).
Table 1. Data file column definitions and descriptions.
