U2004 power sensor VISA

[jgar5427]

Using VISA Read and Write i am able to read power sensor IDN. However when trying to use READ? or READ:PW:AC? command I can obtain only 3 measurements, the 4th one generates  Error -1073807339 occurred at VISA Read in Sensor Read_1.vi    Possible reason: VISA:  (Hex 0xBFFF0015) Timeout expired before operation completed. Any help would be really appreciate it?

Maybe you are not allowing enough time to take the measurement. Increase the Timeout value which is probably set to the default of 10 secs.
