1 Overview
The HS-620 Vibration Meter Kit is a reliable and easy to use hand-held
machine condition inspection instrument. It provides vibration measurement,
alarm indication and a bearing status check facility. The HS-630 kit provides
an additional facility for non-contact temperature measurement. The meter
enables plant maintenance technicians to monitor their machines, find
potential problems in advance of failure, and to ensure machine reliability.

1.2 Overall Vibration Mode
The meter can measure vibration Velocity in mm/s rms, Acceleration in
g peak, and Displacement in
m peak to peak. When measuring
Velocity, and on switching to the ‘Hold’ mode, the meter display will
indicate an alarm status according to ISO10816-3.
1.3 Bearing Status Mode
The meter measures Bg value in g rms and Bv value in mm/s rms which
represent the bearing status. The lower frequency machine vibrations
are attenuated by a 1kHz high pass filter. In the ‘Hold’ mode, the meter
display indicates the bearing alarm status.
1.4 Measurement Units
The meters are available in three different configurations for
measurement units. These are: Metric 1, Metric 2 and Imperial. The
units required must be specified on order – see table on page 5 for units
used in each mode. Metric 1 settings are used throughout the manual.
