*Figures are approximate. File size of captured data is 2GB in GBD or CSV file formate 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.

Hot-Swapping the SD Memory Card

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

 

 

Useful Functions

Displays the data by a bar chart (in firmware ver.1.10 or later)

The integrated data that is measured by the digital sensors can be displayed by a bar chart in the GL840 series.
