Trend Data Operation
From the initial measurement of a patient, trend data (a data point) is
stored in memory every 4 seconds. Up to 50 alarm limit changes can also
be stored in trend data. The N
- 560 can store up to 24 hours of trend data.
The N-560 trend data will be lost if the coin cell battery fails or is
removed. The coin cell battery is located on the main circuit board.
CAUTION: Changing alarm limit settings uses trend memory space.
Change alarm limits only as needed.
Note: Trend memory always contains the most recent 24 hours of
data, with newly collected data overwriting the oldest data on a
rolling basis. The N
- 560 continues to record data points as long as
the N-560 is powered on and an initial patient measurement has
been made, with “blank” data points collected if no sensor is
connected to the N-560 or patient. “Blank” data will overwrite
older patient data if the memory becomes full. Therefore, if you
want to save old patient data, it is important that you turn your
N-560 off when you are not monitoring a patient, and that you
download the trend memory before it fills up and overwrites the old
data with new data (or “blank” data).
