The value of <function>
8.2.13.1 {<function>}:NULL:STATe
Description: Enable or disable the null function for the function specified by <function>. The possible values of
<function> can be found in 7.3.12.
Syntax: {<function>}: NULL:STATe {ON|1|OFF|0}
{<function>}: NULL:STATe?
Parameters: {ON|1|OFF|0}
Example: VOLT:DC:NULL:STAT ON
8.2.13.2 {<function>}:NULL:VALue
Description: Set a null value for the function specified by <function>. See <7.3.12> for the possible value of
<function>.
To use a null value, you must turn on the null state ({<function>}:NULL:STATe ON).
Specifying a null value disables automatic null selection ({<function>}:NULL:VALue:AUTO OFF).
Syntax: {<function>}: NULL: VALue {ON|1|OFF|0}
{<function>}: NULL: VALue?
Parameters: {ON|1|OFF|0}
Example: VOLT:DC:NULL:VAL 0.214
8.2.13.3 {<function>}:NULL:VALue:AUTO
Description: Enable or disable null values for the function specified by <function>. See <7.3.12> for possible
values of <function>.
When the automatic reference selection is turned on, the first measurement made is used as the null value for all
subsequent measurements.
{<function>}: NULL: VALue has been set to this value. Automatic null selection will be disabled.
Syntax: {<function>}: NULL: VALue:AUTO {ON|1|OFF|0}
{<function>}: NULL: VALue: AUTO?
Parameters: {ON|1|OFF|0}
Example: VOLT:DC:NULL:VALue:AUTO ON
