Checking the ultimate vacuum
➨
After any intervention at the equipment (e.g., repair / maintenance)
the ultimate vacuum of the pump has to be checked. Only if the pump
achieves its specified ultimate vacuum, the pump’s leak rate is low
enough to ensure that no explosive atmospheres will occur in the inte-
rior of the equipment.
