For the details, please refer to the 3.20.2 simulate the waveform to verify the
anti-interference performance of the automotive electronics' products.

IT6500C series all come with built-in curves which meet general requirements,
test conditions and tests of electrical and electronic components in motor
vehicles up to 3.5 t.
E-02 Transient Overvoltage Pulse
Transient overvoltages may occur in the electric system due to the switching off
of loads and due to short accelerator tip-ins. These overvoltages are simulated
by means of this test. This test may be used for the electrical life test. The test
pulse of E-02 Transient overvoltage is shown in the next figure.
E-04 Jump Start
External starting of the vehicle is simulated. The maximum test voltage results
from commercial vehicle systems and their increased power supply voltage.
The test pulse of E-04 Jump start is shown in the next figure.
