6.2.2 Nominal values setting
When in the display „TEST“ e. g. the EFT test has been chosen and the „Main“ button has been pressed,
the different parameters of the „Electric Fast Transient test“ can be edited.
The parameter values can only be selected within the range given. If values are chosen that are above or
below the given range the maximum or minimum value will be input automatically.

When the EDIT button has been pressed the dialogue line indicates the possible range like v, f, time, etc.
The values can be varied as follows within the given ranges:
1. Set the cursor to the parameter for editing
2. Edit the values as required using the numerical keys
3. Confirm that the values entered are correct by pressing the ENTER - button.
6.2.2.1.1 definition of EFT parameters
The Repetition, Burst Duration and Spike Frequency are combined in the number of spikes / seconds value
(Spike Rate):
Spike rate [Spikes/s] = (Burst duration [ms] / repetition [ms]) x spike frequency [kHz] x 1000
This formula is only valid if the „Burst Duration“ is lower than the „Repetition“. If the „Burst Duration“ is
equal the „Repetition“, the „Spike Rate“ will be equal to the „Spike Frequency“ (continuous burst).
Spikes per Burst = Burst duration [ms] x Spike frequency [kHz]
