Taking a reading
Using the magnet mount, place sensor on a rigid part
of the machine as close as possible to the desired
measurement point
− For best results sensor should be placed gently onto
measurement point by rolling the magnet onto themachine
− Avoids sudden shocks seen as large acceleration peaks
by the sensor and takes some time to die away
Overall vibration numbers screen displayed
− View of machine’s vibration condition
Three color coded values
− ISO value
− Bearing noise in BDU
− Total g

Reading the display
ISO values
ISO value (in mm/s or inch/s) is the RMS
(average) of the vibration velocity in the
frequency band as specified by ISO
10816-1 standards.
− 10 Hz – 1 kHz (600 - 60,000 RPM)
− 2 Hz – 1 kHz (120 - 60,000 RPMCorrect frequency band is automatically
selected based on running speed
ISO value background is color coded to
ISO 10816-1 vibration velocity level chart
− Indicates the condition of the machine
according to the size and type of machine
selected

Bearing noise
High frequency vibration
Represented in Bearing Damage Units (BDU)
− 100 BDU corresponds to 1g RMS (average)
vibration measured above 1 kHz
− Shows the wear state of bearings

Reading the display
Bearing noise
The higher the number, the more worn the bearing
− 1 g of high frequency vibration (100 BDU) corresponds to a relatively high
level of bearing noise, indicative of damaged bearing
Bearing noise is roughly equivalent to a percentage of bearing wear
Displayed bearing noise levels
− Red: above 100 BDU
− Amber: between 50 and 100 BDU
− Green: below 50 BDU

Vibration analysis
Displays running speed of machine
− Entered manually or use strobe attachment
Vibration velocity (mm/s or inch/s) or displacement (mm or thou)
− Broken into three bands
Shows vibration level in frequency ranges based on multiples of machine
run speed
− 1X = unbalance
− 2X = misalignment
− 3X = looseness

Vibration analysis
1X = Unbalance
Vibration in the frequency band based on the running speed is usually
indicative of how well balanced the machine is
High vibration at the running speed indicates machinery is out of
balance
Even very well balanced machines show some vibration at running
speed
− Should be quite low
− Less than 2.3 mm/sec or 0.09 in/sec for a medium sized machine

Vibration analysis
2X = Misalignment
High level of vibration in the frequency band centered at twice the running
speed is a possible indication of misalignment.
Shaft misalignment can result in a double peak in the waveform due to
two different center of gravity (one from each shaft)
Accelerometer picks up a peak as each center of gravity passes by
− Two positive and two negative peaks each revolution of the shaft
− Gives rise to a vibration signal at double the running speed of the machine

Vibration analysis
3X = Looseness
High vibration in the frequency band centered at three times running
speed indicates something may be loose
− mounting bolts
− weak foundations
Not common to see third order vibration unless there is structural
looseness that is being excited by the vibration of the machine
