int DMMBurstBuffRead(int nDmm, int iSettle, int iSamples)
Following reception of this command the DMM enters a burst read mode, where it takes
iSettle + 1 readings at the set measurement function, range, and reading rate; and saves
the last reading to the on-board buffer. This process repeats for iSamples. No other DM
command should be issued to the DMM until the it completes the operation, and the
buffer is read. One exception is the DMMDisarmTrigger command, which terminates
the process. No autoranging is allowed in this mode. This function is usable for VDC,
VAC, Ohms, IAC, IDC, and RTD measurements. Measurement rate should be set to
10rps or higher. The total time it takes to complete this process is equal to iSamples * (
iSettle + 1) / (measurement rate).
Use the DMMReady to monitor if the has completed the operation, and is ready. When
ready, read up to iSamples, using DMMReadBuffer or DMMReadBufferStr functions
