1.2.4 Measurement Data Logging
Measurement data of each scan interval is sent to the GX/GP/GM as well as saved in the
GX70SM as logging data (up to 4500 points per channel).
When the data becomes full, the oldest data is deleted to save new data.
Even when an error occurs in the wireless communication with the GX/GP/GM,
measurement data is backed up for a certain period.
Logging data can be retrieved using the Wireless Input Unit Configurator and saved as a file
in the PC.

When the GX70SM battery voltage becomes low, a low battery warning is indicated with an
LED.
The GX/GP/GM can monitor the GX70SM battery status and generate a warning output
(relay output) when appropriate.
A low battery warning may occur temporarily when the GX70SM is in the process of joining a
wireless network.
