Introduction
The MTN/VM220 Vibration Meter is a rechargeable, portable instrument designed to operate with a constant current
type accelerometer to provide accurate vibration measurements.
Conforming to ISO10816-3/7, MTN/VM220 will display RMS, peak, peak-peak, crest factor and bearing condition on its
colour screen. Up to 100 time-stamped readings can be stored to non-volatile memory.
The MTN/VM220 is an invaluable trouble-shooting tool for instrumentation engineers familiar with the problems of
plant vibration monitoring, providing an instant readout of the condition of bearings and rotating parts.
2.
Precautions
• Only use the unit as directed in this manual.
• Protect the unit from shocks and extremes of temperature, humidity and harsh environments (such as high salt).
• Use only a soft clean cloth. Do not use solvents or harsh cleaning agents.
• The unit contains no user serviceable parts. Do not attempt to disassemble or repair the unit, as this will invalidate
your warranty.
• To ensure continued performance, have the unit checked and serviced at regular intervals.

Connections
The headphone jack
will accept a 3.5mm stereo jack plug. Headphones (not included) may be used to listen to the vibration
directly.
To avoid hearing damage, use of headphones with an inline volume adjustment is recommended. Ensure the volume is turned
down before connectin
g your headphones. After placing headphones in your ears, gradually turn up the volume until you reach a
comfortable listening level. Do not use headphones when it's unsafe to do so - while operating a vehicle, or during any activity or in
an environment where your full attention to your surroundings is required.

Charging
The meter will automatically turn-off after 15 minutes of inactivity (5 minutes if sensor not connected).
9.
Charging the unit
The supplied multi-voltage charger comes with 4 adaptors and is suitable for use worldwide.
Connect the correct adaptor for your region, plug into mains and connect the mini USB to the MTN/VM220.
The unit should reach full charge within 4 hours. The battery status icon will indicate charging is in progress (see 6.
Display & 8. Battery status).
When the battery is level is low, a warning screen (see left) will display for 5
seconds and the unit will power off.

Connecting sensor
• The sensor and cable can be connected/disconnected at any time.
• Once fully charged, briefly press the power button to switch the unit on.
1 2 3
Connect either end of the cable to
the unit by rotating the connector
to align the key.
Once in the correct position, the
connector will drop into the socket
and the knurl can be tightened to
hold the connector in place. Do
not overtighten.
• Repeat this process to connect the sensor to the other end of the cable.
Notes:
The connection status icon (see 6. Display) will change accordingly.

Measurement modes
Press buttons to switch between measurement modes.
The current mode will be highlighted.
Units for each measurement mode can be set (see 16. Setting units)

Calculation modes
When the unit is in one of the measurement modes (acceleration, velocity, displacement), press buttons to
switch between RMS, peak-peak and 0-peak displays. An additional bearing display is available in both acceleration and
velocity measurement modes. The bearing mode passes the vibration signal through a 1kHz-10kHz band-pass filter to
attenuate non-bearing vibration found at lower frequencies, and is used for more precise monitoring of bearings.

• Crest factor value
• Vibration value & units
The Crest Factor is equal to the peak amplitude of a waveform divided by the RMS value. The purpose of the
crest factor calculation is to give an analyst a quick idea of how much impacting is occurring in a waveform.
Impacting is often associated with roller bearing wear, cavitation and gear tooth wear.

Memory recall mode
Using buttons , select memory recall mode. Press buttons to navigate through memory slots.
When returning to the measurement mode, the selected memory slot will be the current memory slot for the next
store.
It is possible to quickly clear all memory slots (see 18. Clearing memories).
There are 100 memory slots in total. The blue fields shown in the above figure are saved into memory
Provided the unit is returned to Monitran for service, the memories will remain intact, even after battery replacement
and calibration (see 24. After Sales Support)
