Hello JLS..
First i would like explain what i want to do with this VI. I have one power supply and 2 multimeters. after initializing all those guy i would like to start measurement as following. I write specific current to power supply, and writing s completed i wait for a specific time ( thats the reason why i use the timer ), at the end of the waiting time, I want to measure outouts of the power supply and the of other 2 multimeters at the same time (i know that it s not possible, but would be the best solution i dunno),and keeping measurements till i stop. So according to ur suggestion my trigger would be a start command, but why would i use seperate loop for each one?
in the further step, the ratio between signals from meters gonna be my x values as outout of the supply is y. And i ll plot x-y graph.
