Dynamic mode

The dynamic mode of the plotter is used to plot the real time temperature variation with

respect to time. In this mode the sensor measures the temperature at a selected frequency

and in parallel plots that temperature on the graph. The steps to plot the graph in dynamic

mode are as follows:

1.

Select the Dynamic mode from the mode selection drop down menu in the plotter

window

2.

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

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

reading is taken and plotted on the graph.

3.

Click on the Play button in the toolbar which opens the plotter and starts plotting the

graph as shown in Figure 16.

4.

To stop the plotting, click on the stop button in the toolbar.

5.

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

graph as shown in Figure 17.

6.

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

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

7.

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.

8.

In order to see the previously stored graphs, click on the folder icon in the toolbar and

open the .tsg file to view.
