:REFerence <n> Commands
:REFerence <n>
Command syntax:
:RESistance:REFerence <n> Specify reference for Ω
Command parameter:
<n> = 0 to 20e6 Reference for Ω
DEFault 0 (All measurement functions)
MINimum Minimum value for specified function
MAXimum Maximum value for specified function
Query:
:REFerence? Query reference for relative function
Description:
These commands are used to establish a reference value for the specified function. When reference
is enabled (: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 REFerence? query command returns the programmed value.
Conversely, when a reference is set using the :ACQuire command, the :REFerence? query
command returns the acquired reference value.
:STATe <b>
Command syntax:
:RESistance:REFerence:STATe <b> Control reference for Ω
Command parameter:
<b> = 1 or ON Enable reference
0 or OFF Disable reference
Query:
:STATe? Query state of reference.
Description:
These commands are used to enable or disable “reference” for the specified function. When
enabled, the displayed reading will include the programmed reference value. When disabled, the
displayed reading will not include the reference value.
