HP WaterSkis E1312A, WaterSkis E1412A manual NULLOFFSet?, STATe?

:NULL:OFFSet

CALCulate:NULL:OFFSet <value>MINMAX stores a null value in the multimeter’s Null Register. You must turn on the math operation e.g., execute CALC:STAT ON before writing to the math register. You can set the null value to 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 Function” beginning on page 41 for another way to store the offset value.

Example Set the Null Offset Value

CALC:FUNC NULL	Set math function to NULL. You may choose to
CALC:STAT ON	set the math function after setting STATe ON.
	Turn on math operation.
CALC:NULL:OFFS 500	Set null offset to 500.

:NULL:OFFSet?

CALCulate:NULL:OFFSet? [MINMAX] queries the null value.

Example Query the Null Offset Value Set for the NULL Math Operation

CALC:NULL:OFFS? Query the null offset value.

:STATe

CALCulate:STATe OFFON disables or enables the selected math function. The state is stored in volatile memory.

Example Enable the Currently Selected Calculate Math Function

CALC:STAT ON	The selected or default math function is
	enabled.

:STATe?

CALCulate:STATe? queries the state of the math function. Returns “ 0” ( OFF) or “ 1” ( ON).
