FETCh?
This query command retrieves the last set of measurements taken and places
them in the output queue. The returned data will be either a single reading if
‘block’ mode is not selected, or the several readings if ‘block’ mode is selected.
FETCh? (Query only)
CONFigure, INITiate, READ?
Note that the SCPI definition allows <function> and <parameter> qualifiers, but
as the DMM only stores the readings for the current setting, these commands are
not implemented.
The returned data is formatted in the following character positions:

where:
s = the sign + or –
n = ASCII digit 0 to 9
x = either an n or a decimal point
E = ASCII character identifying the exponent
t = a terminator or separator: either ; or , or <lf> (linefeed character)
The measurement overload condition is reported as 200.000E+331
Multiple readings are returned with each value separated by a comma and the last
reading terminated with the linefeed character.
If no measurement has been taken or the instrument has been reconfigured, then
no result is returned and the error–230, ‘Data corrupt or stale’ is stored in the
error queue. This will be as a result of *RST, a CONE, SENSe etc command or
after an INIT command has been sent.
