MAX TIME exceeded error though valid data is returned.

Hi,

 

I am trying to make a multipoint AC measurement with DMM PXI-4071 with the following settings:

 

ConfigureMeasurement(FunctionType.ACVolts, 10, 0.1); //range=10 and resolution=0.1

ConfigureMultiPoint(2, 4, (int)SampleTrigger.Immediate, -1); //trigger count =2, sample count = 4, sample interval=-1

ConfigureTrigger((int)TriggerSource.Immediate, -1); //trigger delay=-1

ReadMultiPoint(10000, 20, readArray, out points);//timeout=10secs, array size=20

 

I get all the 8 samples (Trigger count * sample count) in the array "readArray" and the "points" value is 8. But still i get the MAX TIME exceeded error message (when i check with the ErrorQuery method).

Can anyone help me understand why this happens? I am using NI DMM version 2.8.

Thanks,

Priya.
