Device for bearing diagnostics using shock pulse methodOperation manualSection 4 Operation 21To ensure efficient bearing monitoring the following conditions should be met: Careful preparation for obtaining effective initial values of good bearingand equipment condition; Planned and perfect procedure of periodic data collection; All-around evaluation of any result deviating from the good condition4.3.2. Measurement procedureApplicationThe measurement range of BALTECH VP-3450 allows measuring bearings withthe maximum rotation frequency up to 19,999 rpm and maximum dBi 40.The minimum dBi value is -9dBi; the real limit is 0 dBi, as in case of lowvalues for low-speed bearings it is almost not possible to obtain usefulinformation on the bearing condition.Measurement rangeNormally, a bearing damage develops very slowly, and a measurementinterval is determined according to the following rules:• Bearings should be inspected at least once a month;• Critical equipment and heavily loaded bearings shall be measured morefrequently than standard bearings;• Bearings should be monitored more frequently if their measuring valuesare not stable;• Damaged bearings should be monitored as frequently as possible.NoteAfter bearing lubrication at least one hour should go by before start operatingit.
