The settings were changed. 

Today the voltage of second LC was 13.215V. I stopped the measurement and changed the voltage resolution of both LC to be 10mV.

Restarted the measurement again, with LC1 from 0 to 25V and LC 2 from 13.22 to 25V. 

The resolution was too fine and it would take more than 2 weeks to finish the measurements. Hence, changed resolution for higher voltages. 

The file where data is being saved is same as before.
