NAND mode

1.

This mode is used for logging the temperature data in the NAND Flash present on the

board. This logged data can be viewed at a later time in the graphical format in this

window.

2.

Select the NAND mode from the mode selection drop down menu in the Plotter window

3.

Select the desired frequency (1 second /10 second/ 60second) from the Time Interval

drop down menu. This frequency denotes the timing interval after which the next

reading is taken and stored in the NAND Flash.

4.

Click on the Play button in the toolbar which starts logging the data in the NAND Flash

present on the board. A total of 100 KB of NAND Flash can be used for data logging.

The percentage of NAND used is shown by the status bar in the toolbar of the Plotter

window. The first status bar shows that data is being logged while the second status

bar shows the percentage of data logged.

5.

To stop the DATA LOGGING, click on the stop button in the toolbar.

6.

To read the logged data from the on board NAND, click on the GET DATA icon in the

toolbar. It reads the data from the board and then plots the graph of temperature versus

time as shown in Figure 18.

7.

Use the toolbar present on the graph window to expand or compress the scale on the

graph.

8.

To store the image of the graph on the computer, click on the floppy icon in the toolbar

of the plotter window. It stores the graph as .tsg format.

9.

To store the graph data as text format in an Excel sheet, click on the Excel sheet icon in

the toolbar. It saves the temperature readings in Excel format.
