• TRACE LOGGING
When this setting is on, the trace waveform is also saved when logging data is saved.
This waveform data is saved temporarily to a single file in the internal memory or USB
storage medium.
Temporary save directory
Internal memory (INTERNAL): \INT\AQLOGDAT\LOGTMP.LG7
USB storage medium
\EXT\AQLOGDAT\LOGTMP.LG7
If you restart data logging, the files and directories in the temporary save directory will
be deleted.
For instructions on how to save the temporarily saved waveform data to a normal file,
see section 7.10.
• DESTINATION MEMORY
Selects where the temporary trace waveform data will be saved to.
INTERNAL: Internal memory
EXTERNAL: USB storage medium
If the size of waveform data will be large, use the USB storage medium.
Note
• If you also want to save trace waveforms when logging is in progress (TRACE LOGGING =
ON), the temporary storage area must have sufficient free space for saving waveform data
of all logging measurements.
If there is insufficient free memory space at the start of logging, a warning will appear.
(Warning 151 Disk space is not enough for logging)
If this happens, reduce the number of waveform data values (SAMPLING POINT) or reduce
the logging time to decrease the waveform data size.
• Temporary saved data (LOGTMP.LG7) cannot be loaded as a logging file.
If you want to load it, save it to a normal logging file.
Cursors
If you turn on the cursors, cursor values will appear in the lower right of the graph area.
Cursor C1 and C2 will appear simultaneously. The value of C2 – C1 will appear below
the cursor values.
Scales
The horizontal and vertical scales are automatically set according to the logging
parameter conditions and logging data values.
Zooming is performed in 1-2-5 steps.
Example: The horizontal scale settings change like this: 5 s/div, 2 s/div, 1 s/div
The vertical scale settings change like this: 500 nm/div, 200 nm/div, 100 nm/
div
