:NULL:OFFSet
CALCulate:NULL:OFFSet <value>|MIN|MAX stores a null value in the
multimeter’s Null Register. You must turn on the math operation e.g., execute

any number between 0 and
±
120% of the highest range, for the present function.
MIN = –120% of the highest range. MAX = 120% of the highest range. The null value
is stored in volatile memory. See the section titled “Math Operations - NULL
