The following example measures one or more dc or ac voltages on the 3458A DMM and return the values to the computer. The 3458A DMM uses its
own non-SCPI commands and does not understand IEEE-488.2 commands or return IEEE-488.2 compliant data. Therefore, when the
instrument is not internally storing and returning values using ASCII (15 bytes/reading),
the 3494A control "Enter" command is not used. The IO commmand, "readBytes" is used instead to receive instrument data. The following
data types are read in using the readBytes command:
SINT - 2-bytes/reading
DINT - 4-bytes/reading
SREAL - 4-bytes/reading
DREAL - 8-bytes/reading
