Page 8: Overall Vibration Measurement & Assessment
HS-620/630 User Guide 2.4 Overall Vibration Measurement & Assessment At switch-on the meter defaults to the Velocity measurement mode, with the units ‘mm/s rms’ indicated at the bottom right of the display. If required, press SEL to select acceleration or displacement. Note that no vibration assessment is available on these ranges. -
Page 9: Bearing Status Check
HS-620/630 User Guide 2.6 Bearing Status Check Fix the sensor directly to the bearing housing as close to the bearing as possible. Note that valid high frequency readings are unlikely to be measured using hand pressure and the spike. Press the BRG key to enter the Bearing Status mode. Press the SEL key to select either Bg (g RMS) or Bv (mm/s RMS). -

HS-620/630 User Guide The ISO10816-3 Machine Vibration Standard Industrial machines covered by the ISO10816-3 standard include :- Steam turbines with nominal power less than 50MW Steam turbines with nominal power above 50MW with speeds less than 1500rpm or above 3600rpm (ie. excludes machines included in ISO10816-2 Rotating compressors Industry gas turbines with nominal power less than 3MW... - Page 11 HS-620/630 User Guide Fig.2 ISO 10816-3 Vibration Levels 10816-3 i V The machine mountings affect the resonances related to the basic f f f running speed of the machine. Machines with rubber or spring mountings often vibrate at low speeds following start-up, and as the f f t o l l speed increases the vibration level is reduced.

Page 12: Bearing Status Assessment
HS-620/630 User Guide Bearing Status Assessment When the rolling elements move inside a bearing, broadband noise and n i l vibration is generated. This increases if the bearing is not properly lubricated, or is overloaded due to misalignment or damaged surfaces. r o s i g i l The bearing vibration Bg or Bv measured by the meter is the RMS value... -
Page 13: Bv Value
HS-620/630 User Guide 4.2 BV Values Bv measurement is a long established method for detecting bearing faults which gives reliable indication of bearing condition in 80-90% of cases. The rule-of-thumb assessment used in the meter is as follows:- 1mm/s Healthy bearing, correctly greased BV =1-2mm/s Possibly damaged or un-greased bearing BV >... -
Page 14: Surface Temperature Measurement
HS-620/630 User Guide 5.1. Surface Temperature Measurement The temperature sensor measures the average temperature in a circle of diameter one-eighth of the distance between the surface and the sensor. For example, when the meter is held 1m from a surface, the sensor will respond to a 125mm spot diameter on the surface. -
