Type of Data to Record
You can choose to record display or event data.
• Choosing What Type of Data to Record
Record the type of data that meets your needs. Use the following examples for reference.

Internal Memory
The measured data is partitioned and saved to files at set intervals. If the internal memory
is full or if the number of display data files and event data files exceeds 500 for GX10/GP10
and GX20-1/GP20-1 or 1000 for GX20-2/GP20-2, files are overwritten from the oldest file.
