3.  Set the rising slope, press [Enter] to confirm. 
UP=1A/uS 
4.  Set the descending slope, press [Enter] to confirm. 
DOWN=1A/uS 
5.  Set level A, press [Enter] to confirm. 
LEVEL A=1A 
6.  Set level B, press [Enter] to confirm. 
LEVEL B=2A 
7.  Set the frequency, press [Enter] to confirm. 
FREQ=50HZ 
8.  Set the duty factor, press [Enter] to confirm. 
DUTY=98%(0.1%-99.9%) 
9.  Open  the  transient  test  function,  maintain  on  the  “on”  selection,  press 
[Enter] to confirm.

11.  Press  [On/Off]  to  turn  on  the  input  function,  and  press  [Shift]+[ ] 
(Trigger) to trigger. 
It can be seen that the A/B value is continuously switched, and the number 
of running times is visible in the lower right corner. 
Note 
The maximum number of running times is 65535 and then reset to zero. The 
running times reset does not affect the execution of the transient test. 
12.  Press any key of CC/CV/CR/CW or other composite function keys to exit 
the transient test function. If you need to continue transient test parameter 
setting and perform transient test, repeat steps 1 to 11. 
Pulse Mode 
In pulse 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. 
 
 
Take  CC  mode  as  an  example  (other  modes  operate  similarly).  When  the
