The pressure started decreasing after 45 min and the auto ramp was set to 1 A each 30 s to 86 A
The autoramp was set to 2 A each 10 s to 180 A
The autoramp was set to 3.2 A each 10 s to 300 A
The autoramp was re start at 3.2 A each 10 s to 400 A
The autoramp was set to 1 A each 10 s to 430 A
The autoramp was set to 2 A each 10 s to 450 A
The autoramp was set to 2 A each 10 s to 480 A
Autoramp at 2 A per min to 500 A
Manually tapped to 545 A.
After 48 hrs at maximum temperature, the target was cooled done at -2 A/min |
