6.4.2 Basic Commands FETCh? and READ?
FETCh?
The command
FETCh?
without further keywords and parameter list has a special mean-
ing. While omitting parameters of the parameter list normally means that default values
are used and checked, the current measured value under
FETCh?
is supplied when it is
valid. If a measured value is not yet available, processing is suspended until a valid result
is available.
Usage:
Query only
READ?
The
READ?
command without further keywords and parameter list can be compared with
FETCh?
.
READ?
starts a measurement and returns a measured value without checking
the current settings.
Usage:
Query only
