Starting/Stopping Recording
5.4.1 Starting Recording
The unit starts recording power level when the SET/REC/STOP key is held (long press for
at least 3 seconds) in RUN mode or when the specified start time is reached. The "REC"
indication turns ON when recording starts.
The measured data is recorded and accumulated in the internal memory, and is output in a
CSV file to the SD memory card when the SET/REC/STOP key is pressed.
Important
・If recording starts with recorded data remaining in the internal memory, the remaining
recorded data is lost. To save the data, press the SET/REC/STOP key for less than 3
seconds to output the data to the SD card before recording. Recorded data remaining in
the internal memory is the result of the unit restarting after a power failure or a press of
the reset switch in midst of recording. This situation does not happen if recording is
correctly stopped.
To check for remaining data, press the ▽ or △ key in RUN mode to locate the display
in which the current time is shown at the lower row. Check its upper row, and if its value is
"0", then there is no data remaining in the internal memory.
・The unit cannot start recording while an error message is shown in the display. Remove
the error cause, and cancel the error status by holding the MODE key (3 seconds or
longer). Then, start recording.
Note
・The Power Startup REC Restoration (REREC) function automatically resumes recording (if
it is set to "ON") when the unit restarts after it was accidentally turned OFF during
recording.
・An SD memory card must be placed in the unit when the SET/REC/STOP key is pressed
for data output during recording or when recording is stopped. It is not necessarily the
case at the point when the unit starts recording.
・Disable the write protection of an SD memory card. If it is enabled, an error occurs when
the unit attempts to write data to the card (when the internal memory becomes full) and
recording stops.
・A shift to other mode is prohibited during recording.
5.4.2 Stopping Recording
The unit stops recording and outputs files to the SD memory card when the SET/REC/STOP
key is held (long press for at least 3 seconds) during recording ("REC" is ON) or when the
specified end time is reached. The "REC" indication turns OFF when recording stops.
Important
A write-enabled SD memory card must be inserted in the slot when stopping recording. If
a data output attempt fails, recording stops with the recorded data in the internal memory
retained and the error message is displayed. Hold the MODE key (3 seconds or longer) to
cancel the error status. Insert an SD memory card and output the recorded data file to the
card by pressing SET/REC/STOP key. Do not start recording before the data in the
