DEFault 0 (all functions)
MINimum Minimum value for specified function
MAXimum Maximum value for specified function
Query :REFerence? Query programmed reference value
:REFerence? DEFault Query *RST default reference value
:REFerence? MINimum Query lowest allowable reference value
:REFerence? MAXimum Query largest allowable reference value
Description These commands are used to establish a reference value for the specified
function. When Reference is enabled (see :REFerence:STATe), the result
will be the algebraic difference between the input signal and the reference
value:
Reading = Input signal - Reference
From the front panel, reference is called relative (REL).
The :REFerence <n> command is coupled to the :ACQuire command. The
last command sent (:REFerence <n> or :ACQuire) establishes the reference.
When a reference is set using the :REFerence <n> command, the :REFer-
ence? query command returns the programmed value. Conversely, when a
reference is set using the :ACQuire command, the :REFerence? query com-
mand returns the acquired reference value.
