High E (mV) = 0 -3276 to 3276
Low E (mV) = 0 -3276 to 3276
Initial Direction = Negative Negative or Positive
Pulse width (msec) = 250 1 to 32000
Sensitivity = 1
µ
A/V 100 mA/V to 100 nA/V (10 pA/V with the
Low Current Module)
Specific parameters
Number of Steps = 2 1 or 2
Quiet Time (sec) = 2 0 to 65535
Graphics Menu
Single Graph
displays the
Current vs. Time
plot as the default plot. The
Cottrell plot (
Current vs. 1/sqrt (Time)
) can be selected using the
Data
Type
drop-down list box in the
Graphics Options
dialog box.
Analysis Menu
The
Auto
option for
Results Graph
displays the plot selected in
Data Type
,
and the slope, intercept and correlation coefficient are listed in the
Main
window. Since data at early time points can be distorted due to the finite time
required for the potential step, the
Auto
option uses only the last 80% of the
data. An alternative line can be defined by the user through the
Manual
option (the line is specified by the X values of 2 points on the plot). The units
for the slope are mA
