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 metre is as follows:
• BV < 1mm/s
• BV = 1-2mm/s -
• BV > 2mm/s
5. Temperature Mode (HS-630 only)
The HS-630 uses a thermopile infra-red sensor to indicate temperature in Deg. C or Deg.
F on the display. An alignment laser beam is provided to indicate the area where the
temperature is being measured. Ambient temperature is also indicated in the bottom left
of the display.
