[2] Result reading

Data from the last measurement is read. (No instruction is sent to execute an operation.)
See pages 13-15 to 13-25 for details about the measurement data blocks.
(1) Measurement data reading function 1 (fixed measurement data): code 21
The final evaluation result, based on the results of the last measurement, and the data in block 0,
which comes from the measurement functions specified for measurement numbers 0 to 3, are
output.

The measurement functions vary in terms of the data they produce. Only the data in block 0 is
output from the complete output data produced by each measurement function.
