I'm trying to set up a CV experiment using an Arbin battery cycler, however when I try to save I get an error message saying that the Schedule must contain at least one step (presumably referring to the 'Step/ Limit' tab). I have tried adding a short 'rest' (OCV) step for 10 seconds to the 'Step/ Limit' tab, however when I run the schedule it finishes immediately after the rest step and does not transition to CV.
I've also tried dismissing the error message that says the Schedule must contain at least one step and trying to save anyway, but the Schedule fails to save when I do this.
I've followed the manual and made sure that CV is enabled in the Advanced Options of the configuration file, and I'm able to edit steps under the CV tab. I also followed the example in the manual for setting up a CV schedule, but this resulted in the above error.
Is there an additional setting that I need to change, or have I missed a key step?
Dear Liam Bird ,
ask for saving some data, say "'1 measurement' per second", in your data recording file, during your (1st) short 'rest' (OCV) step[1a].
Also, the Voltage limits (VLow1, VHigh1), in your (2nd step), CV1, should include the latest OCV1 values (VLow1,< OCV1 < VHigh1). Otherwise[1b], this CV1 (2nd step) is bypassed, without your notice.
So, retry to begin with (initially, very much) extended, new, testing (VLow2, VHigh2), Voltage limits: (VLow2
Dear Ioannis Samaras ,
Thanks so much for your detailed answer.
I think I have managed to include the first part of your answer by adding a 'log' step to record the voltage each second (i.e. 'DV_Time').
However, my cell voltage (OCV) is ~2.3 V, and I set my CV limits as 1.5 V and 2.8 V, so hopefully this shouldn't cause a problem regarding the second part of your answer.
I think the problem might be in the 'Step/ limit' tab - when I set the 'PV Channel Time' step limit and set the schedule to progress to 'Next step', is it possible to direct the schedule to go to the CV schedule (i.e. that defined in the CV tab) as the next step (There is no next step defined within the 'Step/ limit' tab)? Currently I can't find a way to link the schedule defined in the 'Step/ limit' tab to steps defined in the 'CV schedule tab', however I'm not able to save and use the schedule with the 'Step/ limit' tab blank.
Thanks again for your help - it's really appreciated.
Dear Liam Bird ,
you can't find a way to link (to) the 'CV schedule tab', because we need (must) to give a definition (by name) to the 'CV' step, in a previous time; so, now, define a helpful nick name: say 'CV1', for your 'CV' step.
After, and only after, the definition/nomination (above: 'CV1'), then we can, say a (new) way to, ' l i n k ' (by name) (i.e. GOTO that step ('CV1').
Also, you are (/might be) not able to save and use the new schedule, because it was, previously, protected/flagged, from another (administrator or even a power) user, as 'RO' (Read Only)[1].
1. In this case, try to:
a) rename the filename of your modified/expanded schedule, or even you need to
b) change the (absolute, full) 'Path/filename'.
