4 conclusions: 4.
1 the bottom liner of the diluent container creates wrinkles and prevents the diluent level sensor to activate when the container is empty.
4.
2 the issue of wrinkles created at the bottom of the diluent container has only been observed in the european containers.
These containers use a double-liner construction and the inner liner separates from the outer liner which creates wrinkles that prevents the float in the level sense from activating properly.

3 further investigation of this item is in progress.
Customer has two instruments but has not yet confirmed which instrument experienced the reported incident.
