General
Safety Precautions
To prevent possible electrical shock, fire, personal injury or the device
damage:
• Carefully read user’s manual.
• Do not place sensor on the objects which exposed to high voltages.
These voltages could cause personal injury or death.
• The Analyzer could not be used in potentially explosive
environments.
• Take measures to prevent cables and straps become entangled by
rotating part of machines at measurement site.
• Do not expose 107VF parts to heavy impacts, high humidity and
extreme temperature.
• Do not try to open the display unit –this can damage the system, and
your after-sales service warranty will come void

Overview
The 107VF Vibration Analyzer (Device, Analyzer) is a compact yet
powerful, vibration analyzer designed to measure overall vibration
parameters, FFT spectrum analysis of the rotating machinery,
immediate evaluation against ISO 10816 standard, condition
monitoring by route based measurements and data collection. Route
files and data files exchange via email makes it ideal for data collection
at remote sites. Simple in use, with free firmware upgrades, comes
with data management and reporting software.

Measurement functions
Vibration mode –analyzer measures overall level of vibration
acceleration, velocity and displacement and FFT spectrum, route or
off-route measurements.
Tachometer –analyzer measures speed of rotation by means of
contactless optical sensor. The measurement result is displayed in RPM
and Hz.
IR thermometer –contactless measurement of object temperature.
The measurement result is displayed in °C and °F.

Settings
This menu is used to:
- set Date/Time
- Sensors setup
- Units setup
- Auto OFF delay setup
Date/Time
Use arrow keys to set date.
Hold then press or for month
decrement/increment.
Confirm by when correct date is set.
Use keys to set minutes and hours.
Use key to switch focused field. Focused field is
indicated by red frame.
Confirm by when correct time is set.

Sensors
Use keys to choose
sensor, which will be used for
measurements. Drop down
menu offers two types –IEPE
or charge type sensors to
choose from.
Confirm choice by key.
Type, S.N. and Sensitivity fields are editable.
Use key to choose field to edit.
Then use arrow keys to edit the field value.
Units
This option is not implemented yet..
Auto OFF
Use keys to set auto OFF delay (minutes).
Press or key to confirm and quit menu.

Vibration
Analyzer measures vibration Acceleration, Velocity
and Displacement. In ISO 10816 mode
measurement result is compared to the built-in
table of vibration severity grades according to
ISO 10816-3.
Use keys to choose measurement mode.

Vibration measurement settings
Press key to enter Settings menu.
Use to choose parameter to setup.
Use to change parameter value.
Low Freq –lower frequency limit. Can be set to 1, 2, 10 Hz.
Hi Freq –upper frequency limit. Can be set:
- from 200 to 10000 Hz for Acceleration;
- from 200 to 5000 Hz for Velocity;
- from 200 to 800 Hz for Displacement;
FFT lines –FFT spectrum resolution. Can be set to 400, 800, 1600 lines.
Trigger –not implemented yet..
Averaging –measurement averaging. Can be set in range of 0 to 64.
Zero means that averaging is OFF.
Window –weighting function. Can be set to Hanning or Rectangular.

Taking measurements
Choose vibration parameter e.g. Velocity, edit
settings if needed, then press key to start
measurement.
When measurement is running:
Use key to toggle FFT
spectrum / waveform display.
Press key to stop/resume
measurement.
When measurement is stopped:
Press key for Options:
Save.. –to save measurement data. Press key
to proceed.
Format –Linear/Logarithmic amplitude display.
Use to change parameter value.
Zoom –frequency axis display zoom change. Use to change
parameter value

To save measurements
Press key to stop measurement
Press key for Options
Choose Save.. and press key
Device will enter My documents
menu
Browse to the destination folder,
then press key save
measurement.
Device writes two files at a time –FFT
spectrum file and waveform file.
Device remembers path to the last written files.
To create new folder –press key. Date/time stamp is used as a
default name for new folder.
To create folders with meaningful names –connect device to the PC
via USB as external flash drive, then create folders using PC keyboard.
