thermocouple?

What happens to the recorded data if the power of the device is suddenly turned off?
If the sampling interval is less than one minute, data is recorded to the SD memory card every minute, so it is
possible that even data from one minute ago may still be there.
However, if there is a power failure while recording data, you may not be able to play back the data.
If there is a possibility of power failure such as momentary power failure, install the optional battery pack (B-569).
If the optional battery pack (B-569) is installed in the main unit, it will automatically switch to battery operation
and continue recording.
During recording, stop recording and establish the data before the battery runs out.
Therefore, no data will be lost even if the battery runs out.
