Trying to write a vi to do a current-voltage sweep with Keithley 2410 hooked up to Labview with GPIB. The vi is attached, as well as screenshot. According to the manual, if I do not set a manual voltage setting time, and use default NPLC (1PLC), each voltage point should have 3ms automatic voltage setting time (with the current range I'm in), then come the measurement which is 1/60 s = 16.7 ms, so the measurement time for one data point should be 16.7 + 3 = 19.7 ms. However, when I run the program and read the time stamp, 100 data points takes 7.2s, which averages each data point takes 72 ms, which is significantly longer than it should. I triple checked the wiring to make sure everything is correct. Am I doing anything wrong here? Thanks a lot for your time!
