Hi
I am currently using LAbiew 7.1 to measure the debounce time response of various products by closing a relay across the DUT switch contacts.
I have a PXI 2570 relay card and have written a VI which accepts a relay number and the close time.
However I am using the software millisecond timer which sometimes does not accurately activate the relay for the time specified.
I presume Windows is getting in the way as say I close a relay for 50ms, most of the time its accurate but occasionally it expands to 60 or 70ms.
Is there any facility on this card to accurately close the relay for a specified time repeatedly ?
Attached is my VI
Thanks.
