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 dis-

play.

This command is functional only if the instrument is on the speciﬁed mea-

surement function. Sending this command while in any other function caus-

es 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.
