CSV format	3 days	12 days	18 days	36 days	91 days	182 days	Over 365

Figures are approximate. File size of captured data is 2GB in GBD or CSV file format on this chart.
Sampling interval is limited by the number of channels in use.(10ms:1ch, 50ms:5ch, 100ms:10ch)

Ring capture function

The most recent data is saved when the memory is configured in ring memory mode. (Number of capturing data is 1000 to 2000000 points)

Relay capture function

Data is continuously saved to multiple files up to 2GB without losing any data until capturing is stopped when the memory is configured in the relay mode.

Memory loop function

In addition to the existing relay capture function, the oldest file is automatically deleted before memory capacity runs out.

Hot-swapping the SD memory card

SD card can be replaced during data capturing when the sampling interval is 100ms or slower.

Back up recording data

The data file can be created periodically for purpose of backing up data while recording it, and the file is automatically transferred to another storage device on the unit or FTP server on the network.

Backup interval: 1, 2, 6, 12, 24 hour(s)
Backup file destination: SD memory card or FTP server
Data file format: GBD (binary) or CSV (text)

The CSV format is available with firmware version 1.43 or rater.
• Available sampling speed is the 100 ms or slower when using the CSV format.
• When the RING mode or external pulse synchronization sampling is selected for recording, the backup function is not available.
• The storage device specified as the recording destination of the measurement data can not be set as the transfer destination of the backup file.
• When backup is enabled and data file format is specified with CSV format, SD memory card exchange (hot-swapping) and RELAY recording are not available.

Data file verification

It is a function to check the integrity of the data file when replaying the data file. It compares check-sum generated from the data file and recorded check-sum. When two check-sums do not match, the data file may be corrupted or has been changed by someone. The check-sum code is recorded into the file when data file is created by the GL unit.

Check-sum code is added to normal data recording file and also file created for backup, ring or relay recording. Adding check-sum is available for data files created in GBD format.When the recorded data file is converted and saved using GL100_240_840-APS or GL-Connection software, the check-sum code will not match.
This function is available with firmware version 1.43 or rater.
