Test application parameters
You must enter test parameters that are consistent with the following values. Otherwise, you may
receive unsettled and inaccurate measurements.
The Cyclic Voltammetry test application parameters are listed below.
Model 2450-EC
• Potential range: -20 V ≤ E ≤ +20 V
• Current measure ranges: 10 μA, 100 μA, 1 mA, 10 mA, 100 mA, 1 A
• Source limit (compliance): 100 % of selected current range
• Scan rate: 0.1 mV per second to 3500 mV per second
• Potential step size during scanning:
• 100 μV (0.1 mV per second ≤ scan rate < 35 mV per second)
• 1 mV (35 mV per second ≤ scan rate < 350 mV per second )
• 10 mV (350 mV per second ≤ scan rate ≤ 3500 mV per second)
• Number of cycles: 1 to 100
