4.2.2.1.2. CHARGE MENU
The user may set the charge voltage and current, and initiate
charging from here.
4.2.2.1.2.1. SET VOLTAGE
From this screen the user may set the voltage they wish to
charge the load to. The right and left buttons control which
digit is presently being edited, and the up and down buttons
increment or decrement that digit. Pressing Enter will exit this
screen and save the voltage.
4.2.2.1.2.2. SET CURRENT
From this screen the user may set the maximum current with
which they wish to charge the load. The right and left buttons
control which digit is presently being edited, and the up and
down buttons increment or decrement that digit. Pressing
Enter will exit this screen and save the current.
4.2.2.1.2.3. CHARGE CONFIRM
At this screen, the user is asked to confirm the charge voltage
and current, and begin charging the load.
4.2.2.1.2.3.1. CHARGING
This screen displays the present output voltage and
current. It transitions to the Voltage screen (4.2.2.2)
when the output voltage reaches the set point.
Charging may be aborted by pressing the Cancel
button.
4.2.2.1.3. DISCHARGE CONFIRM
At this screen the user is asked to confirm their intent to discharge
the capacitor bank. If the user confirms, the capacitor starts
discharging, until the load voltage reaches 10VDC. The time the
capacitor takes to discharge to half of its starting voltage is
measured, and from this value the load capacitance is calculated.
4.2.2.1.3.1. DISCHARGING
This screen displays the present output voltage and
discharge current. It transitions to the “Results” screen when
the output voltage reaches 20VDC.
4.2.2.1.4. RESULTS
This screen presents the user with the results of the previous
capacitor discharge and measurement.
4.2.2.2. VOLTAGE
If the system is idle and no button is pressed for fifteen seconds, the
system will transition to this screen, displaying the present load voltage
and leakage current. Pressing left or right will transition back to the main
menu.
