Measurement and Data Send Codes are used to measure (
M
Command) and then specify returned data
or acquire values without making a measurement (
D
command).
Either a
D
or an
M
can precede any of the following codes. For example,
M1 or D1
–
M602 or D602
. If
an M command is sent, a measurement will always be made even if the Data Code does not request
measured values. For example, if
M116
is sent to the instrument, a measurement is made then a list of
accessories is returned from the instrument.
In the following table,
qqqqq
is the returned error code. If
qqqqq
is all zeros (00000) no error has
occurred during the request. All other values for
qqqqq
relate to an error condition. Refer to the
Remote Mode Error Code section of the manual for a complete list of error codes and their meanings.
UUUU
