6.1.4.4 Test duration TEST TIME.
The test duration can be selected between 1 and 29999 s (8h33). This is the test time per
coupling path. In the case of multiple coupling paths, eg. L, then N, then PE the total time to
complete all three paths will be TEST TIME x 3.
To increase the test time, it is possible to loop a program with itself so it runs continuously until
START / STOP is pressed.
6.1.5 Synchronisation
The Synchronisation menu enables spikes to be produced at random, or to be synchronised to a
defined source.
Internal detection of the reference source is between the following:
- a signal from the external filter available at the connector P90 EXTENSION.
- a signal from the front panel SYNC IN connector.
- an internal signal ( 50 or 60 Hz ) corresponding to the supply frequency of the PEFT Junior.
Synchronisation is defined in relation to the first impulse of a burst.

6.1.5.1 Random burst distribution RANDOM
The RANDOM function, enables impulses to be distributed in no fixed relationship within the
range SPIKE FREQ.to SPIKE FREQ. - 50 %.
