Hi all,

I've got an error during the gpc report: Accuracy Error: Deviation is so high that it is most likely due to anomaly in the data.

What is the problem?

What will be the consequence conerning the suggested chem id?

Please find zip.data and GPC-Report.Data_7.05.20.zip Data_7.05.20-report.zip

Thank you so much.

Hi Sebastian,

I see the discharge current varies quite a bit in your log file. I would suggest you try again using a fixed C/10 discharge rate (10mA) and submit your IVT log file again.
