Saving Data in the Internal Memory
In Chart Recorder mode, up to 1000 divisions of the recorded data are automatically
saved in the internal memory. The required section of the data that has been cleared
from the screen can be redisplayed after the recording is finished by using functions
such as search & zoom (limited to the data in the range defined by “Number of Data
Points That Can Be Saved” below). As with the normal data (data when the recorder
mode is OFF), cursor measurements, automated measurement of waveform parameters,
normal statistical processing*, search & zoom, and display setting modification in the
DISPLAY menu can be performed on the redisplayed data. The redisplayed data can
also be saved as waveform data in the same fashion as normal data.
Furthermore, the redisplayed data can be reprinted by changing the print conditions or a
PDF file of the reprint image can be created (see “Reprinting on the Built-in Printer” or
“Creating a PDF File of the Reprinted Image” on page 2-46).

Cycle statistical processing and statistical processing of history data cannot be performed in
Chart Recorder mode.
Number of Data Points That Can Be Saved
If the chart speed is slow, the number of data points that can be saved in the internal
memory is reduced. For example, if the chart speed is 10 mm/h, up to 100 divisions
of data (up to 4 days of data) are saved. If the chart speed is 20 mm/s, up to 1000
divisions of data (up to 8 minutes 20 seconds of data) are saved. The maximum
number of divisions that can be saved for each chart speed is as follows:
Chart Speed
Maximum Number of Divisions That Can Be Saved
20 [mm/s] to 1 [mm/s]
1000
100 [mm/min] to 2 [mm/min]
1000
1 [mm/min]
500
100 [mm/h]
1000
50 [mm/h]
500
25 [mm/h]
250
20 [mm/h]
200
10 [mm/h]
100
For the relationship between the chart speed and sample rate, see appendix 15.
Functions That Cannot Be Used in Chart Recorder Mode
When making measurements in Chart Recorder mode, history memory, GO/NO-GO
determination, dual capture, and waveform computation cannot be used. (The
HISTORY, GO/NO-GO, DUAL CAPTURE, and MATH keys cannot be used.)
In addition, items set with the ACQ key cannot be changed.
Compatibility with the Measured Data
The measured data in Chart Recorder mode is not compatible with the measured data
when the recorder mode is OFF. The measured/saved data in Chart Recorder mode
cannot be loaded with the recorder mode turned OFF, and vice versa. The measured
data on the DL750 and the measured data on the DL750P (when the recorder mode is
OFF) are compatible.)
