Description These commands are used to enable or disable Reference for the speci-
fied function. When enabled, the displayed reading will include the pro-
grammed 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 ac-
quired 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 mea-
surement 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 com
-
mand is sent.
The :ACQuire command is coupled to the :REFerence <n> command.
See the description for :REFerence for details.
