I am using keithley 2400 as source meter.
I've downloaded labview driver 8.0 and use the vi as following sequence
Initialize -> configure output -> output On -> close
I set this to a current source, with output current = 0.18A and voltage compliance = 10V and connect to a LED
My problem is, the LED will not turn on during the very first time.
I need to manually set the instrument to LOCAL, then hit the output button to ON, then i see the LED is on, and then OFF it,
Since then, i trigger again using my software, then only it is working now.
if i power off and on Keithley instrument and try again with my software, it will not work.
Everytime i need to manually set the output ON OFF first.
I suspect this is related to some configurations before i turn on the output.
I am running out of idea. anyone can help on this?
