multiple input limit range from multiple channels

[Piiwee]

Hallo I´m kinda new to LabView and need some information,

I use a Multifunction DAQ 16 Bit with the following specifications:

1. M-Series
2. NI PCI 6250
3. Operated by Microsoft XP

My problem:
* I would like to use 4 analog input channels from my M-Device to measure 4 diffrenttypes of voltage. The resolution from each channels varying from +/-10, +/-5, +/-1, etc (those are the possible range if i dont misunderstood the Data sheet from NI). I have tried to use a daqmx create task in a For-Loop so that vi runs only 1 input limit for 4 times and then put all the signals in the daqmx create channels.
The vi does execute the measurement but I dont get the right scale that I want.

Thanx for the info

Hi,

Do you mean you are able to acquire from each of those channels but not display with that scale limits on graphs??

Hi Devchander,

yes exactly, that is what I mean. Actually I could get the right scale if I use a simulated  input (I configure a simulate analog input channel with MAX on my PC) but once I try my program on my device, i cant get the right scale that I want to.

So sorry if you are confused, because english is not my native langguage.

Hi Piiwee,

You are doing just great with your English.

I got an idea as to what your problem is.

Just Have a look at attached VI.

it should solve your problem.

I have used chart instead of graph

I have stacked the 4 plots one over other and auto scaled each(  you can also set scale of each graph by going to properties)

Hope this helps
