Run the Charge standard technique by selecting Experiment > Electrochemical Energy > Charge from the Framework™ menu bar. This initiates the following sequence of events:
1.Framework™ creates a Runner window, and the PWR Charge.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 charge begins. Readings are taken at fixed time-intervals during the charge. The charge runs until either a stop criterion is met or until the maximum time specified in the setup parameters step.
6.If you specified a subsequent Voltage Finish in the setup parameters, a potentiostatic hold (performed galvanostatically with a software feedback loop) is performed. This hold runs until either the current falls below a specified level, or for a user-specified maximum amount of time. The data are displayed on the same voltage and current plot.
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.
