A complete operational test was performed using a stainless steel grinding vial set. With the chamber empty, the low-LN₂ alarm was active; once the chamber was filled with liquid nitrogen, the alarm cleared, confirming that the liquid nitrogen level sensor is functioning properly. All control buttons are responsive, and the lid open\/close motor operates correctly. During the run, the impactor was audible, consistent with normal operation. This unit does not include the optional auto-fill accessory (SPEX 6820).
