How does DHMSCare judge vibration after stops and load changes?
DHMSCare checks whether a machine is running before it judges the vibration. Readings taken while the machine is stopped are set aside. A machine that runs at several speeds is compared with its own normal level at each speed. When vibration settles at a new steady level, for example after a load change, DHMSCare checks whether the operation changed. An operating state your team confirms gets its own normal level.

DHMSCare checks whether a machine is running before it judges the vibration. Readings taken while the machine is stopped are set aside.

When vibration settles at a new steady level, for example after a load change, DHMSCare checks whether the operation changed. An operating state your team confirms gets its own normal level. An alert moves up to critical only when the rise keeps growing over days or a second sign confirms it. One such sign is a matching pattern in the vibration spectrum, the breakdown of vibration by frequency.
