Flooded Sample Chamber 3
The instrument with the flooded sample chamber is continuing to generate purge fails when the instrument attempts to bring itself down to zero following a group of stand-alone cal checks. DVM is continuing to wander up and down so when the instrument sets zero, it is sometimes much lower than it should be.
On other occasions the instrument simply crashes part way through a group of cal checks because it is unable to find a stable DVM to rely upon as zero.
