【 REAL/AVG 】

key  enter  the  real-

time measurement  mode.  The  current  circuit  is  measured  in  real  time  and  the 
measurement parameters  cannot  be  modified  in  the  measurement  mode.  If  the 
parameters  need  to  be modified,  the  test  needs  to  be  stopped  first.  Event  analysis  will  not 
be  conducted  during  the real-time test, and event analysis will only be conducted after the test 
is stopped.
