Acquire measurement data on the Memory HiLogger, and start recording.
When recording stops depends on data recording settings (repeat recording,
triggering, timers, etc.). (p. 78)
When you want measurement data to be automatically saved, before starting
recording, check that auto-save is enabled (p. 46), that a CF card or USB flash drive
is correctly inserted (p. 94), and that sufficient storage capacity is available (p. A11).
Starting and Stopping Recording
Press the START/STOP key.
The green LED lights.
When using the trigger function, the times when measurement
starts and when recording (data acquisition) starts are not the
same.
A confirmation message appears when you press the
START/
STOP key to start recording. Save important data to a CF card
or USB flash drive before starting, because previous measure-
ment data will be overwritten when recording starts.
