The script creates the Setup dialog box, which becomes the active window and accepts changes in the experimental parameters. This Setup box 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. If the Advanced Pstat Setup is on, a second Setup dialog box containing hardware-configuration details becomes the active window, so you can modify the hardware configuration.
The potential of the sample is set to the Initial E plus N times the step height If a DME, SMDE, or HDME electrode has been specified in the Electrode Settings, a New Drop pulse is issued. This potential is applied for Tstep – Tpulse. At the end of this time, a current measurement is made.
The cell voltage is returned to the Initial E. This new voltage is held for Tpulse. At the end of this time, a second current measurement is made..
The secoond current measurement is plotted versus the potential prior to the pulse. If Autoranging was selected in Setup and Tpulse < 20 ms, after each point the current range is automatically switched to the optimal range for the measured cell currents. Note: If Line Rejection has been checked in Setup and if the pulse time is long enough (40 ms for 50 Hz or 33.3 ms for 60 Hz), each current measurement represents the average current measured over one complete line cycle (mains cycle).
The cell is turned off. The script pauses to allow you to view the curve you have just collected.
