Experimental Sequence for Potentiostatic Intermittent Titration Technique (PITT)

Run the PITT standard technique within the Sequence Wizard. This initiates the following sequence of events:

  1. The Framework™ software creates a Runner window, and the pitt.exp script is run in this window.
  2. The script creates the first Setup dialog box and accepts changes in the parameters.
  3. After you click the OK button, a second dialog box is displayed, containing additional parameters.
  4. The script now obtains the use of the potentiostat specified during Setup, and opens the data file specified in the Output name. The Runner window’s Title reflects the Output filename. If the potentiostat is in use or the file cannot be opened, the script returns to the Setup dialog box.
  5. 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 output file contains only this information. This header information includes: (a) Tags identifying possible analysis; (b) The current time and data; and (c) A list of setup parameters.
  6. The cell is turned off and the specimen’s Eoc is measured. The last measured potential is recorded as Eoc.
  7. The cell is turned on.
  8. The voltage pulse is applied for the set duration.
  9. The cell is turned off.
  10. The rest period begins for the set duration.
  11. The pulse magnitude is adjusted by the defined value, and steps 7-10 repeat until the Final E parameter is reached
  12. 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.
