To set the Current Range:
1. Select Current Range.
2. Choose a value. Note that the choices are different depending on your potentiostat.
Figure 69: Selecting the Current measure Range
The current measure range constrains the maximum current that will flow through the device under
test (DUT). Make sure to choose a range higher than your expected maximum current. Setting the
current range also sets a current limit, which can be used to stop the test or otherwise protect your
DUT. Your potentiostat will limit the current to 105 percent of the selected range.
Now you will adjust the Period. This setting lets you specify the duration of one cycle of the pulse
wave. The Period and Pulse Width settings are related. You cannot set the Pulse Width to a value
more than 99 percent of the Period. Adjusting the Period may also change the Pulse Width setting
automatically.
To adjust the Period:
1. From the Pulse Settings screen, select Period.
2. Enter a value.

3. Select OK.
