Storage Folder and File Name
Automatically Saved Log Files
When log files are automatically saved with Save Log File checkbox ON in toolbar:
| Item | Description | Notes |
|---|---|---|
| Storage folder | "folder path entered in toolbar Log Folder" + "\\" + "3-digit number shown in toolbar No field" | No value is determined when monitoring starts. The application checks whether subfolders 000-999 exist under the folder specified in Log Folder, and uses the smallest non-existing number. |
| Log file name | "string entered in toolbar Log File Name" + "_" + "Ch number (1-1, 1-2, ..., 4-2)" + ".csv" | If split-save is enabled in options, an underscore and split number (4-digit sequence from 0000) are inserted between channel number and extension:"Log File Name" + "_" + "Ch number" + "_" + "split number" + ".csv" |
tip
If all subfolders 000-999 already exist under the folder specified in Log Folder, an error appears at monitoring start and monitoring cannot start.
Manually Saved Log Files
When saved manually by clicking 
in Analyze Window:
| Item | Description | Notes |
|---|---|---|
| Storage folder | Folder path specified in file dialog | |
| Log file name | File name specified in file dialog | Default file name is:"Ch" + "Ch number (1-1, 1-2, ..., 4-2)" + "_" + "monitoring start datetime or log merge datetime (YYYYMMDDhhmmss)" + ".csv" |
