Hey, guys.
I'm very new in this of labview, I do some programs using always drivers to control instruments. So recently I have the job to control a Keithley 2410 SMU. I do a simple program to source constant voltage, and measure current vs time. This program works wells in short periods and the Keithley functions very well. But a week ago, I have to used for 20 hrs, the problem was that at 45 min of functioning, the frontal screen of SMU unit went off, the labview show an I/O error that can communicate with the instrument, and when I reboot the instrument it can't do anything, and the labview is not capable of communicate with the instrument. The unit is manufactured when is functioning as a source and measurement unit to not to be damaged with high currents, and so the last measurements was about 100mA when the compliance level was at 1A. When I power on the unit, I only hear the fans and I can't do nothing, I look for the fuse but It was ok.
So I know this is a Keithley Hardware error not related to NI. But I have the idea that maybe something that i put in my program damage the instrument in some way.I control the instrument with a serial cable, and I used the drivers that I downloaded from a NI page, dont remember what version was. Just need help to see if it's something bad that I do, damaged the instrument
Greetings to all.
