1190 !This subprogram writes commands and parameters to the Command
1200 !and Parameter registers. It calls Wait_not_bsy prior to writing the next
1210 !command or parameter. Once a command and its parameter(s) are written,
1220 !it calls Wait_done and Err_chk to check for any errors.
1230 !The subprogram also stores the measurement function, range, and aperture
1240 !time so that the right routine (in subprogram Read_data) is used to
1250 !convert the measured signal to the appropriate quantity.

This subprogram retrieves the reading(s) from the multimeter’s data
1500 !buffer and converts it to the appropriate quantity (i.e. voltage,
1510 !resistance) based on the measurement function, range, and aperture time.
1520 !The subprogram calls Data_ready to determine when the readings are
1530 !in the data buffer.
