One has to manually press "Stop Magging Up" button before magging down even though the current stays above 9A (reads 9.00581 A) for a half an hour.
When target temperature is chosen to be 0 K, the log box shows "Starting regulation to 0.1 K from 9.00581" but the regulation box shows 0 K. This is confusing.
Regulation is completed when the current is still quite high (a good fraction of an ampere, TmK > 120 mK). Do not display the log message until the current reading is less than let's say 0.01 A or remove phrase "Mag up and try again."
