test circuit 2 for i h parameter. r -v p v bat = - 48 v surge generator d.u.t. this is a go-nogo test which allows to confirm the holding current (i h ) level in a functional test circuit. test procedure : 1) adjust the current level at the i h value by short circuiting the ak of the d.u.t. 2) fire the d.u.t with a surge current : ipp = 10a , 10/1000 m s. 3) the d.u.t will come back off-state within 50 ms max. smp30-xxx series 4/6
