Run the Leakage Current standard technique by selecting Experiment > Electrochemical Energy > Leakage Current from the Framework™ menu bar. This initiates the following sequence of events:
1.Framework™ creates a Runner window, and the PWR Leakage Current.exp script is run in this window.
2.The script creates the Setup dialog box which becomes the active window and accepts changes in the experimental parameters. This Setup window remembers the experimental settings from the last time this script was run. To restore the parameters to the values defined in the script, click the Default button.
3.The script now obtains the use of the potentiostat specified during Setup and opens the data file using the Output name. If the potentiostat is in use or the file cannot be opened, the script returns you to the Setup dialog box. The file header information is written to the data file. This information is written to the file prior to data acquisition. If the experiment is aborted, the file contains only this information. This header information includes:
•Tags identifying possible analyses.
•The current time and date.
•A list of the Setup parameters.
4.The cell is turned on.
5.The main experiment begins. The instrument runs in potentiostat mode and applies a constant potential to the cell. The resulting current-flow is recorded.
6.The data are displayed as current versus time and voltage versus time. On the current-vs-time plot, the amount of leakage current as a function of time appears.
7.The data are written to the output file, and the script cleans up and halts. After the experimental sequence is complete, the cell is turned off. The acquired data are written to the output file. The script then waits for you to click the F2-Skip button. After you do so, the script closes everything that's open, including the Runner window.
