An outside of the united states (ous) customer contacted a siemens customer care center.A siemens customer service engineer (cse) was dispatched to the customer¿s site.During this visit, the cse performed an instrument grounding and leakage inspection.The inspection focused on verifying the integrity of ground connections, measuring earth bond resistance, and identifying any potential issues affecting electrical safety.It was determined that the relative humidity in the lab was low and out-of-specifications, the fans' mounting plate was loosely tightened on the atellica sample handler chassis, which could potentially affect the quality of the electrical grounding of these components.The screws were subsequently tightened to ensure proper contact and grounding.The cse did not find any electrical measurement values indicating a grounding issue.Both the earth bond tests and the continuity tests were found to be acceptable.Siemens further evaluated the event and concluded that that the shock felt by the user at the back of the atellica sample handler was the result of electrostatic discharge (esd) due to user-buildup of static electricity, out-of-operating-specification relative humidity in the laboratory, and the loose hardware used to mount the rear fan plate to the chassis.The instrument is performing according to specifications.No further evaluation of this device is required.
