Phase
The device under test is disconnected from the supply and the voltage at the test
terminals starts to fall. Once the rms voltage falls for 10V the instrument starts the
timer.
Phase
After the voltage drops below an internally calculated voltage value the timer is
stopped. The instrument re-calculates the measured time to a value as it would be
if the disconnection occurred at the maximum voltage value.
(1) peak voltage
(4) Ulim
(2) voltage at disconnection time
(5) moment of disconnection
(3) calculated voltage value
(6) discharging time
