Viewing the results on the front panel
The I-V characteristics of the diode can be seen on the front panel of the instrument using the
graphing function.
To view the graph:
1. Press the MENU key.
2. Under View, select Graph.
The default settings for the graph show time on the x-axis and the measure results on the y-axis.
However, it is possible to plot current and voltage against each other to generate an I-V plot.
To enable I-V graphing:
1. In the graph screen, select the Data tab located at the top of the screen.
2. Under the Graph Type option, select Scatter/IV.
3. Select the Graph tab located at the top of the screen to return to the graph.
