1.1.3 Fail-safe Saving of Recording Data
l
Data storage
The GM supports long-term recording and multi-channel recording.
Measurement data is constantly saved in internal memory and can be transferred periodically to
an external storage medium (SD card). Moreover, the FTP client function can be used to provide
data redundancy using a file server. Measurement data is saved without fail even in a sudden
power interruption.
Data can be saved automatically or manually to an external storage medium.

Data types
Based on the sampled measurement values, the GM can recorded two types of measurement
data: event data and display data (the data type depends on the GM settings).
Measurement data is saved to internal memory as data files.
For details, see section 3.1.2, “Recording.”
