Hello All,
I designed a relay board which is controlled by a USB DAQ-6501 to perform pin to pin resistance measurements (See Block Diagram). The board is powered by an Agilent E3646A power supply and the resistance is measured by an Agilent 34401A multimeter. The issue I am having is when I perform a read with the Agilent 34401A multimeter I see to get intermittent timeout issues. The VI seems to execute correctly and provides correct data. However, the program run time is extremely slowed down by the intermittent timeout issues. I tried clearing the read/write buffer for the Agilent multimeter read but that did not seem to resolve the issue. Am I doing something wrong in my code? Am I trying to communicate with to many serial instruments? I've attached my project with VIs. Any ideas or help would be appreciated.
Cheers,
E
