Press the
Function
button to toggle through the 3 main measurement parameters; as well
as RPM and Frequency readings. The three main measurement scales are typically used
for vibration testing.
a)
Acceleration
: Normally measured in m/s
2
has excellent high frequency capabilities
and is therefore very effective in determining faults in bearings or gear drives.
b)
Velocity
: The most commonly used vibration parameter. It’s used for vibration
severity measurements in accordance with ISO 2372 which contains guidelines for
acceptable vibration levels of machinery under different power categories. These
guidelines are presented in a table in the back of this manual. Velocity is typically
measured in cm/s or Inch/s RMS (centimeters or millimeters per second).
Note
: this
instrument measures in cm/s. If you are more familiar with measurements in mm/s
or need to compare your measured values directly with the vibration severity chart in
this manual, you must multiply the value by 10.
c)
Displacement
: This parameter is typically used on low speed machines because of
it’s good low frequency response. This is NOT recommended for monitoring bearings.
Units are measured in Mil or mm equivalent peak-peak.
Calibration:
The DVM does not need a scheduled (daily, weekly, monthly) calibration performed however,
the calibration should be verified yearly by Phase II or a qualified calibration facility.
Battery Replacement:
When the battery symbol appears on the display, its time to replace the batteries.
Slide the back cover off and remove and properly dispose of the old batteries. Replace with fresh
set of batteries paying careful attention to the polarity.
Maintenance:
Be sure to keep this unit free of dirt, dust, liquids or viscous fluids. Its also best to store this unit
in a temperature controlled environment when not in use for a long period of time.
If the DVM-1000 malfunctions, contact Phase II tech support directly for instructions. Any
attempt at internal repair will void any stated or implied warranties.
