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 (see :REFerence <n> and :ACQuire). When disabled, the
displayed reading will not include the reference value.

Description When one of these commands is sent, the measured input signal is acquired
and established as the reference value. This command is typically used to
zero the display. For example, if the instrument is displaying a 1µV offset,
sending this command and enabling Reference (see :STATe) zeroes the
display.
This command is functional only if the instrument is on the specified
measurement function. Sending this command while in any other function
causes an error. Also, if the latest reading is overflowed (“OFLO”) or a
reading has not been triggered (“----”), an error occurs when this command
is sent.
The :ACQuire command is coupled to the :REFerence <n> command. See
the description for :REFerence for details.
