This is the default screen while the system is idle, displaying the present
terminal voltage and indicating that the system is ready for operation. If the
system is idle in another screen and no button is pressed for a period of time,
the system will transition to this screen. Pressing Enter will transition to the

main menu.

From this menu, the user may input the variables necessary to execute a
complete capacitor test cycle. A test cycle is broken into three distinct
stages: charging the capacitor with a constant current, holding the set
voltage for a specified amount of time, then discharging the capacitor at
the same constant current, during which measurements are taken. See
Figures 4-3 and 4-4 for detailed examples. In the event that the voltage
drops too rapidly during discharge to make accurate capacitance
measurements, the test will return to the hold stage, then attempt the
measurement again at a reduced current. The ESR measurement uses
a pulse technique and will similarly automatically adjust the current to an
appropriate value.
