How to use the nidmm.attributes.AttributeViString function in nidmm

Specifies the amount of time in seconds the DMM waits between measurement cycles.  This attribute only applies when the NIDMM_ATTR_SAMPLE_TRIGGER attribute is set to INTERVAL.
    On the NI 4060, the value for this attribute is used as the settling time.  When this attribute is set to 0, the NI 4060 does not settle between  measurement cycles. The onboard timing resolution is 1 µs on the NI 4060.
    The NI 4065 and NI 4070/4071/4072 use the value specified in this attribute as additional  delay. On the NI 4065 and NI 4070/4071/4072, the onboard timing resolution is 34.72 ns and  the valid range is 0-149 s.
    Only positive values are valid when setting the sample interval.
    The NI 4050 is not supported.

    Refer to the NIDMM_ATTR_FUNCTION topic in  the NI Digital Multimeters Help for device-specific information.
    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.

Call niDMM_GetNextInterchangeWarning  to extract interchange warnings.  Call niDMM_ClearInterchangeWarnings  to clear the list of interchangeability warnings  without reading them.
    Interchangeability checking examines the attributes in a capability group  only if you specify a value for at least one attribute within that group.   Interchangeability warnings can occur when an attribute affects the behavior  of the instrument and you have not set that attribute, or the attribute has  been invalidated since you set it.
