Hi,

You just have to try different things. Experiment with the VI's you got from Hameg. Changing current should be just like changing voltage, just replace the voltage-VI with the current-VI.

This is instrument-specific.  Probably you should read the operational manual for this power supply at the very least to see what it is capable of doing.

Thanks Bill.

I am tryng to shut my powersupply off after finishing all the process but in the instrument driver vi there is no any vi for power off or software off.

now i am trying to design that logic can you give me any idea regarding to this that how can i shut off my power supply by using vi.

[dkfire]

What do you mean by shut off the power supply?

If you want to turn off the output terminats, have you tried the "hmp4000 Configure Output State.vi" ?

[AnkitRamani]

ya thats same turn off.

I am trying with that let's see.

thank you.if suppose i have problem then i ll post here.

[AnkitRamani]

hiii,

i have connected led with subvi and i want to turn it on when my power is on.

here in attachment i have attach that power on vi,as well subvi so you will get clear idea about my problem ,

is there any changes i have to do to turn on led because generally when there is any error in vi then led will on to show that there is error,but i want to make led on when  there is no any error.

You have to invert the data line with a "NOT".

You can also right-clik on your boolean and change the colors. Green when OK and RED if error for instance.

thank you very much 

i ll try it now..
