(Reference Output query) Returns the present value of the reference when editing the
output (error mode). If not editing the output using the INCR command, the return is 0
(0E+00). The reference value is set with the OUT, NEWREF or MULT commands. To
determine which quantity is being edited, use the EDIT? and OUT? commands.
Response: <reference value>
Example: REFOUT? returns 0E+00
