Shift + S-Tran LEVEL A= X.XXXA You are being prompted for the first current value.
Press the 5 key for 5 A.
Enter Enters the 5 A value, then displays WIDTH A = X.XMS. You're being
prompted for the duration of the 5 A load -- press the 3 key for 3 ms.
Enter Enters the 3 ms value, then displays LEVEL B= X.XXXA. You are being
prompted for the second current value. Press the 1 and 0 keys to enter
10 A.
Enter Enters the 10 A value, then displays WIDTH B = X.XMS. You're being
prompted for the duration of the 10 A load -- press the 2 key for 2 ms.
Enter Enters the 2 ms duration, then displays :CONTINUOUS, :PULSE, or
:TOGGLED. Use the △ or ▽ arrow keys to display :CONTINUOUS.
Enter Returns to the standard display of voltage and current.
To activate this continuous transient condition, press Shift + Tran, then press On/Off. The load will
begin switching between the two Tran values with the timing you entered.
Pulse transient operation
In pulse transient operation, the load operates at the A value that has been entered until a trigger is
received. At the trigger, the load switches to the B value and stays at that level for the B timing
value. Then the load switches back to the A value and stays there until another trigger is received.
