Pretreatment Time [s] is the duration at a soak value, Initial Value. After the
pretreatment period, the scan will begin at the Initial Potential [V]. Steps in the
experiment are inserted via the arrow buttons circled in red in Figure 18b. The first step
after the pretreatment is step “0”. By clicking the box next to Hold/Ramp/Step (Fig.
18d), the user can select the potential or current control required. VRTX Value is the set
point of the Hold/Ramp/Step. Rate/Time to Next is scan rate or time between steps,
depending on which control mode the user is in. In Figure 18b, step “0” is a “ramp to” 1
V at a rate of 0.5 V/s. Figure 18c shows step “1” set to a “ramp to” -1 V at a rate of 1
V/s. Figure 18d and 18e show the selection of step “2”, which is initially grayed out, as
“step to”, and the selection of “step to” as 0.5 V. In the case of the “step to” selections,
the Rate/Time to Next input box is not used and can be ignored. Figure 18f shows a final
“ramp to” 0 V at 1 V/s in step “3”. Repetitions, if used, will repeat the experiment
starting at step “0”. If the Cell ON After Measurement box is selected, the potential will
soak at the Standby Value when the experiment is complete.
