Slow measurement when using NI DCPower

[Jan_HeG]

Hi,

In my application I use a PXI-4110 and the NI-DCPower VI's.

The problem is: the current time bottleneck is the voltage measurement. (using the niDCPower measure.vi) This VI use ~60ms to run, and as the voltage will be measured rather often this large delay is the most time-consuming part in my code!

Accuracy is not important, so is there any tricks or things I can do to reduce the time required to measure the voltage?

To take that much time, it sounds like you are initializing inside a loop - the same loop where you are reading. Or, you are doing the equivalent of starting /stopping the task once per loop iteration. Post a screenshot of the read loop for more help.
