Query state of reference
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.
PRINT #1, "output 16; :curr:ac:ref:stat on; stat?"
' Enable reference
PRINT #1, "enter 16"

Acquire Reference for TEMP
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 2mA 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.
PRINT #1, "output 16; :func 'volt:dc'"
' Select DCV function
SLEEP 1
' Allow reading to settle
PRINT #1, "output 16; :volt:dc:ref:acq; stat on"
' Acquire and enable refer-
ence
PRINT #1, "output 16; :volt:dc:ref?"
' Query reference value
PRINT #1, "enter 16"
' Get response from 2002
