Ice-Nucleation-Controller version

1.2.12

Area(s) with issue?

Ice Nucleation Controller, Temperature Controller

Steps to reproduce

When starting new measurement, temperature controller sometimes peaks to 100%. Starting system at 10°C, gradient close to 0K/min.

✔️ Expected Behavior

Slow and steady increase with minimal overshoot.

❌ Actual Behavior

Overshot significant.

~5K/min overshoot

Update Gradient calculations appear to be significantly off once system temperature readings start. Investigations should be made to ensure gradient calculations are correctly handled.
