niDMM_Control
ViStatus = niDMM_Control(ViSession Instrument_Handle, ViInt32 Control_Action)
Purpose
Controls the DMM. Use this function if you want a parameter change to be immediately reflected in the hardware. Use this function before calling niDMM_Initiate to make the initiate call as quickly as possible.
 |
Notes The NI 4050 and NI 4060 are not supported. Calling this function while the DMM is taking measurements results in an error. After the DMM is finished taking measurements, calling this function will make any unfetched data points unavailable. |
