High-level Functions	N/A

Enables the instrument to operate in additional voltage ranges where instrument specifications may differ from standard ranges. When set to VI_TRUE, this attribute enables extended voltage range operation. Review specification deviations for application suitability before using this attribute. NI recommends setting this attribute to VI_FALSE when not using the extended voltage range to avoid unintentional use of this range.

The extended voltage range is supported only for PPMU, with the output function set to DC Voltage. A voltage glitch may occur when you change the PPMU output voltage from a standard range to the extended voltage range, or vice-versa, while the PPMU is sourcing. NI recommends temporarily changing the SELECTED_FUNCTION attribute to Off before sourcing a voltage level that requires a range change.
