Before Executing Your Program Before executing a program that uses the capacitance compensation subprogram,
you must link the subprogram to your program as follows. The subprogram is in an
ASCII file on the E5250A Program Disk.
1. GET the file C_COMPEN from the E5250A Program Disk.
GET "C_COMPEN"
2. RE-STORE the file.
RE-STORE "C_COM"
3. Load your program.
4. Link the subprogram to your program by using the LOADSUB statement.
LOADSUB ALL FROM "C_COM"
Error Messages If error occurs, following error message is displayed, and program is paused:
Parameter Out of Range Improper parameter value. Confirm and enter the
available value.
