5.4 Starting/Stopping Recording

5.4.1 Starting recording

When holding the SET/REC/STOP key (for at least 3 seconds) in RUN mode, recordings of
the differential pressure data start and "REC" turns ON.
The measured data is recorded and accumulated in the internal memory, and is output as a
CSV file into the SD memory card when the SET/REC/STOP key is pressed.
Important
 If a recording starts when the recorded data still remained in the internal memory, the
recorded data will be lost. When pressing the SET/REC/STOP key for less than 3 seconds
before recording, the file can be output to the SD memory card. A state in which the
recorded data remains in the internal memory occurs due to a power failure or the reset
switch being pressed during recording and therefore the Differential Pressure Station
restarted. If a recording stop operation is performed properly, the recorded data will not be
remained.
 In RUN mode, press the  or  key to display the time at the lower line. If the value in the
lower line is 0, there is no recorded data in the internal memory.
Note
 The SD memory card is not always required to be inserted during recording. However, it
needs to be inserted when pressing the SET/REC/STOP key or while the recording is
stopped.
 Move to another mode other than to RUN mode is prohibited during recording.

5.4.2 Stopping Recording

When pressing the SET/REC/STOP key (for at least 3 seconds) while "REC" is turned ON
during recording, the recording stops and the file is output to the SD memory card, and "REC"
is turned OFF.
Important
 Be sure to insert a writable SD memory card when recording stops.
 Even though the writing to the SD memory card failed, recording will not stop.
 If the SD memory card cannot be ready when you want to change the operation mode due
to setting changes, press the reset switch or shut down the power supply and then restart
the unit. Although the data recorded in the internal memory before a restart will be
maintained even after the restart, the data will be lost after recording starts. Insert the SD
memory card before starting recording and press the SET/REC/STOP key to output the file.
