Section 8: Measuring I-V characteristics of a solar panel Model 2460 Interactive SourceMeter® Instrument User's Manual
In the example above, the instrument is programmed to display custom text on the USER swipe
screen using the display.changescreen and display.settext commands. After the test is
finished, the display will indicate the maximum power (P ), the short circuit current (I ), and the

After the code is executed, five values are returned in the Instrument Console of Test Script Builder
(TSB), and the measured current, voltage, and calculated power are displayed on the front panel of
the Model 2460. You can copy the data from the TSB Instrument Console into a spreadsheet such as
® ®
Microsoft Excel for graphing and further analysis. The figure below shows the results of graphing
the data in an Excel spreadsheet. Notice that the test on the solar panel was executed with light (light
ON) and in the dark (light OFF).
