Memory management
The generator includes commands to manage its internal memory resources. These
commands or useful if the generator exhibits degraded performance or other anomolies.
To verify and correct memory related anomolies:
1. Check the generator’s memory for corruption by running a memory self test:
MEMT // runs the memory self test
MEMT ? // returns the results of the memory self test
1 // returned value from the memory self test
A value of “0” indicates no memory corruption or inconsistency was found. A value of
“1” indicates that there is a memory anomoly.
2. If the memory self test reveals a memory corruption, re-initialize the generator:
BOIT // re-initializes the generator
3. If the memory self test does not reveal a memory corruption, check to see if there is
enough free memory and contiguous memory:
MEMF? // queries for the free memory
808320 // returns the amount of free memory
MEML? // queries for the largest contiguous block of free memory
816568 // returns the largest contiguous block of free memory
If the amount of memory is low or the amount of contiguous memory is low the memory
should be compacted.
4. Compact the generators memory:
MEMC // compacts the memory
MEML? // queries for the largest contiguous block of free memory
818280 // should show larger block of contiguous free memory
