Sweep rate XXXXXXXXmV/s
Function Voltage ramp for cyclic voltammetry.
Parameter Range; Default value / Meaning
U.start -3000...3000 mV; -
Initial voltage
Initial voltage for the voltage ramp.
U.end -3000...3000 mV; -
Final voltage
Final voltage for the voltage ramp. This voltage is retained after the end
of the sweep until a new voltage is applied or until it is switched off by
ØMEAS or END in the main program on the "OP.SEQUENCE" page.
U.step 1...12 mV; 5 mV
Voltage step
Voltage step for direct current ramp.
The following condition holds for the definition of U.step:
U.step
–––––––– < 100 V/s
t.step
t.step 0.1...9.9 ms, 0.01...9.99 s; 1.0 ms
Time interval for voltage step
Time interval after which the voltage in the sweep is increased or
decreased by the amount U.step.
The following condition applies to the definition of t.step:
U.step
–––––––– < 100 V/s
t.step

Ramp slope
Here, the slope of the direct current ramp is displayed in mV/s. It is
calculated as follows:
