The c501 module serial number was (b)(6).Calibration was last performed on (b)(6) 2023 and was acceptable.Qc was acceptable.There is no indication of an issue.The centrifugation speed was 5000 revolutions per minute (rpm).This speed may be too fast based on the sample tubes used.The field service engineer (fse) found the cause of the event was aged electrodes.The fse cleaned the electrode compartment, replaced the o-rings in the acrylic blocks, and replaced the electrodes.Calibration, qc, and a 21-cup precision were all acceptable.The service actions resolved the issue.
