Did you check the manual??

Maybe your OCP isn't between the potential window, is it?

Can you describe what you want to do, e.g.:

-charging at constant current....(value) until the potential becomes higher than ...(value) or

- charging at constant potential....(value) until the current becomes lower than...(value) or 

- charging at constant power

and similar for discharging. 

I suppose you need to do repetitive charging/discharging cycles.

I think you are at the first try. What I see in the image is discharging at constant current -1mA, until potential becomes lower than -4000mV. (I suppose you don't want this behaviour). If E< -4000mV the sequence ends and the method skips to the next sequence.

Observe that you can put charge/discharge in the same or in different CP/CA/CC sequences.

Thanks for you all,

I want charge using CC in certain voltage window, for example from 0V to 0.5V

and discharge with same condition (-ve CC). but unfortunately the dive goes to different potential with no control.

You can see the attached file, the technique has the option of "stop if" max. pot & min. pot. but only for one direction (-ve or +ve current).

I hope if I can find such a technique that I can control the potential window of both charging and discharging.

Any Help? 

thanks in advance  

 You may link two successive GC methods to have a charge/discharge cycle. 

I created a complete sequence for you, but I failed to send it here. If you accept, I can send it by e-mail. Send me a message at [email protected] .You may try it or use it as a model.

Thank you very much Dr. Radu, 

I sent email to via my email ([email protected])
