NIDMM_ATTR_FUNCTION
Specific Attribute

Description
Specifies the measurement function.
 |
Note If you are setting this attribute directly, you must also set the NIDMM_ATTR_OPERATION_MODE attribute, which controls whether the DMM takes standard single or multipoint measurements, or acquires a waveform. If you are programming attributes directly, you must set the NIDMM_ATTR_OPERATION_MODE attribute before setting other configuration attributes. If the NIDMM_ATTR_OPERATION_MODE attribute is set to NIDMM_VAL_WAVEFORM_MODE, the only valid function types are NIDMM_VAL_WAVEFORM_VOLTAGE and NIDMM_VAL_WAVEFORM_CURRENT. Set the NIDMM_ATTR_OPERATION_MODE attribute to NIDMM_VAL_IVIDMM_MODE to set all other function values. |
