Hi,
I am working with Labview 2017 I want to increase voltage gradually from zero to 600 in steps of 5 volt when 600 voltgae limit is achieved I want Keithley should deliver 600 volt and do not OFF its power. I have an VI but meter out put does not hold its output gets off when its reaches peak limit.
Please help and suggest solution.
My target is to start from zero in steps and hold meter output ON when reahced 600 volt.
Solved! Go to Solution.

That might not be an option.
You might have to step though voltages yourself.

Thanks for reply.
Could you please help me in providing such VI with option to apply voltage by myself please.

Hi,
I am going through very hard time I am using 6517B for providing voltage. I required to increase voltage in step upto 600, once the maximun limit is achieved 6517B should hold its output at 600 I need to take measurement at 600 constant voltage level.
I request to please help me.

There are lots of ways to go about that.
In a simple while loop. Set a voltage, do measurement, wait a while, stop when done.
In a state machine. Make an init state, a next step state, a measure state, etc..
A sequences or state pattern. If you're into OO...
I don't have those drivers installed, but this is more about general LabVIEW programming. You'll need just a bit more structure to get it done.

6517B Keithley Stair Case sequence and remain powered ON when reached Stop Voltage

Thanks for reply.
I think I could not explain it clearly actually, I have to start measurement once the 6517 output reached at peak level means 600V, for each step I have no need to take measurement. Just want to reach at 600V through steps and hold it at 600V.
Please suggest in this scenario.

The scenario is mostly the same, simply remove the measurement.
The driver should have a set voltage VI. Simply call it in a for loop or while loop, with a wait in it. Create ramp of values, or use 'i' X step voltage as an input.

Sounds like several states in a state machine.
What is your problem with implementing a state machine with several states?
And please don't spread this discussion over several threads…
