REMOTE 
ERASURE 
The C3 command allows you to erase the entire calibration 
memory.  The  erasure  is  executed  by  sending the string 
"C3  CO"  (equivalent  to  pressing  ERASE  and  then 
STORE). 
Any 
command other than 
CO 
after C3 will abort 
the erasure. To facilitate remote  calibration, the 
CO 
com-

mand  does not  timeout 
as 
does the  front panel 
ERASE 
button. The selective erasure that is possible from the front 
panel  is  intended 
as 
a  troubleshooting  aid,  and  is  not 
available over  the  IEEE-488 Interface. 
Note that the erase command can take up to 3 seconds to 
execute. To prevent timeout problems with the controller, 
you  must  determine  when  the  command  is  completed 
before continuing. Several methods are presented in Tirn- 
ing  Considerations,  above.
