Resolving the 'H# Abort: Count Rate Too Low' Error on Your LS 6500

Service AI

The 'H# value' failure in your Beckman Coulter instrument could stem from issues with the front-end electronics, such as the photomultiplier tubes (PMTs), the pre-amp housing assembly, or the high voltage power supply. Another potential culprit might be the Cs137 source drive.

To determine if the front-end electronics are operational, performing a simple Counts Per Minute (CPM) test is the most straightforward method. Valid sample counts from this test suggest that the PMTs, pre-amp housing assembly, and high voltage power supply are functioning correctly. Conversely, invalid counts may indicate a malfunctioning pre-amp board, often located in the pre-amp housing to the left near the cooling fan, as frequently observed in similar cases.

Should the front-end electronics pass the CPM count test, attention should then be directed to the Cs137 source drive. It's critical to verify that the source spring, which is responsible for maneuvering the radioactive source, is in working order. In instances where the mechanical movement is not at fault yet the problem remains unresolved, it is prudent to engage the services of a trained professional for in-depth analysis.
