analog input mV or V?

[labview1958]

I am trying to measure the mean voltage value of an analog DC signal. I have already set up the equipment together with a NI 6025E Daq card and a temperature sensor. The temperature sensor sents a signal to the computer via the DAQ card. I have made an labview program to change the voltage signal to temperature. Q: Is the program measuring the incomimg signal in V or mV? I assumed it was in mV and made the program based on that. However I am away from the lab for sometime and I cannot test it. Again is the incoming measured in mV or V? Here is part of the program: [URL=http://img51.imageshack.us/my.php?image=forumtempearature5nx.png][IMG]http://img51.imageshack.us/img51/7931/forumtempearature5nx.th.png[/IMG][/URL]

I am attaching the labview program in 6.0. Does the mean.vi gives the output in V or mV?

The mean doesn't know (or care) if the input is volts, millivolts, or parsecs. It just calculates the numeric mean of the input array. Unless you've created a custom scale in MAX, the output of AI Acquire Waveform is in volts. You can easily test this for yourself. Connect a know voltage to one of the DAQ inputs and look at what's being returned.
