Description

Specifies whether NI-DCPower automatically selects the voltage limit range based on the desired voltage limit for the specified channel(s).

If this attribute is set to NIDCPOWER_VAL_ON, NI-DCPower ignores any changes you make to the NIDCPOWER_ATTR_VOLTAGE_LIMIT_RANGE attribute. If you change the NIDCPOWER_ATTR_VOLTAGE_LIMIT_AUTORANGE attribute from NIDCPOWER_VAL_ON to NIDCPOWER_VAL_OFF, NI-DCPower retains the last value the NIDCPOWER_ATTR_VOLTAGE_LIMIT_RANGE attribute was set to (or the default value if the attribute was never set) and uses that value as the voltage limit range.

Query the NIDCPOWER_ATTR_VOLTAGE_LIMIT_RANGE attribute by using the niDCPower_GetAttributeViInt32 function to find out which range NI-DCPower automatically selects.

This attribute is applicable only if the NIDCPOWER_ATTR_OUTPUT_FUNCTION attribute is set to NIDCPOWER_VAL_DC_CURRENT.

Defined Values:

NIDCPOWER_VAL_OFF (0) NI-DCPower does not automatically select the voltage limit range.
NIDCPOWER_VAL_ON (1) NI-DCPower automatically selects the voltage limit range.
