Bakeout test completed. Maximum temperature reached within baking volume was 120 degrees, with baking stopped by the program due to detection of
negative temperature gradients. Negative temperature gradients due to a couple of thermocouples becoming unsecured and moving to cooler part of baking
volume. Attached documents show temperatures of thermocouples. The colour of plots are linked (all of chamber temperatures are blue etc). Temperature |
