Description
Specifies the measurement range. Positive values represent the absolute value of the maximum measurement expected. The specific driver is expected to coerce this value to the appropriate range for the instrument. Negative values represent the Auto Range mode.
There is a dependency between the IVIDMM_ATTR_RANGE attribute and the IVIDMM_ATTR_RESOLUTION_ABSOLUTE attribute. The allowed values of IVIDMM_ATTR_RESOLUTION_ABSOLUTE attribute depend on the IVIDMM_ATTR_RANGE attribute.
Typically, when the value of the IVIDMM_ATTR_RANGE attribute changes, the instrument settings that correspond to the IVIDMM_ATTR_RESOLUTION_ABSOLUTE attribute change as well. This is true regardless of how the change of measurement range occurs.
The value of the IVIDMM_ATTR_FUNCTION attribute determines the units for this attribute.
