11.9 SAMPLE DATA BLOCKS
These data were acquired using an RC network and a constant current laboratory transmitter.
The RC network is as follows:
Block 0010 is the program header and is written to the data cache only when the operator goes
between Menu 2 and 3.
Block 0011 is the main data block and is written at the end of each data acquisition cycle, when
Enter
is pressed in answer to the instruction: "CONTINUE to save, ESCAPE to
discard".
