They are portable, easy-to-use digital dynamic balancers. In
addition, they can do quick, efficient vibration analysis,
allowing the user to identify additional sources of vibration.
The Vibrex 2000, Vibrex 2000 Plus and Enhanced Vibrex
2000 Plus were developed to meet the dynamic balance
needs of the aviation community.
Although primarily intended for light aircraft propeller
balance, they perform as well as the world-famous
Honeywell Model 177M and Model 8350 “ring-of-lights”
Vibrex products developed for rotary-wing applications.
The Vibrex 2000, Vibrex 2000 Plus and Enhanced Vibrex
2000 Plus are not limited to the aircraft field. Like their
predecessors, these products are usable in a wide range of
uses, including agricultural, forest product-related, marine,
and industrial applications.
2.2 Product Description
This section gives a general description of the Vibrex 2000,
Vibrex 2000 Plus and Enhanced Vibrex 2000 Plus systems,
including the differences between the two products.
NOTE: See the “Glossary” for definitions of specific Vibrex
2000, Vibrex 2000 Plus and Enhanced Vibrex 2000 Plus related terms that may not be familiar to the user.
Keep in mind that the Vibrex 2000 Plus system and Enhanced
Vibrex 200 Plus have all the capabilities of the Vibrex 2000. In
addition, it has the added features and benefits listed under
Section 2.2.2 “Vibrex 2000 Plus Enhancements and Section
2.2.3 Enhanced Vibrex 2000 Plus Enhancements”.

the exact differences between the three models, see Section 2.3
“System Specifications”.
2.2.1 Vibrex 2000 System Overview
The Vibrex 2000 unit is a hand-held, battery-powered vibration
analyzer. It is a vibration analysis and balancing tool that rapidly
and accurately acquires and analyzes aircraft vibration data. It
uses that data to calculate balance solutions and to analyze
aircraft vibration levels across a broad frequency range.
The Vibrex 2000 system provides accurate helicopter vibration
readings for chart calculations on main and tail rotors, shafts, and
blowers. As a spectrum analyzer, they provide the operator with
an overview of rotor and drive-train vibration. The Vibrex unit
uses cables and transducers (for example, the Honeywell Model
7310 Velocimeter, magnetic pickups, and photocells) from
previous generations of our equipment, further reducing the cost
of ownership.
2.2.1.1
System Operations
The Vibrex 2000, Vibrex 2000 Plus and Enhanced Vibrex 2000
Plus systems allow the user to do the following operations:
Propeller Balance Operations - Easy-to-understand menus let
the user initiate up to four different balancing jobs at one time.
The instrument can automatically correct for the propeller
response to weight changes, and the user can save this correction
for future balancing operations.
A “first round hit” solution means lower vibration solutions,
even on the first move. Two channels allow the user to measure
the propeller and rear of the engine during balancing. All
measurements, solutions, sensitivities, and annotation are saved

in memory and can be reviewed on the instrument, printed out on
the optional portable thermal printer, or downloaded to a
personal computer (PC) through a standard RS-232 serial cable.
Rotor Track-and-balance Operations - The track-and-balance
menus are designed to simplify taking multiple measurements
without having to change the setup. The user can acquire and
save balance readings, in inches per second (IPS) and clock
angles.
The user can also track up to seven helicopter blades, using the
Honeywell Model 135M-12 Strobex Tracker.
Spectrum Analysis - Vibration peaks listed by frequency or
order are available up to 24,000 RPM (600,000 for V2K+). The
lists are based on 400-line fast Fourier transform (FFT)
calculations. As with all measurements, the lists can be saved,
reviewed, printed, or transferred to a PC.
The user can save the complete spectrum and view it with a
standard spreadsheet or with one of Honeywell's ground-based
software packages. Up to twelve orders and associated halforders can be listed.
2.2.1.2
System Benefits
The Vibrex 2000 systems offer the user the following benefits:
Reduced aircraft operating costs and down time
Reduced propeller and rotor vibration that translates into
increased reliability, increased mean time before failure
(MTBF) for avionics, as well as mechanical and
aerodynamic structures
Better ride comfort for pilots and passengers

2.2.1.3
Self-Test Feature
Each time the Vibrex 2000, Vibrex 2000 Plus or the Enhanced
Vibrex 2000 Plus unit is powered up, it checks its memory and
characterizes its analog filters to compensate for aging
components, temperature drifts, and so on. The unit then reports
the total amount of time the batteries have been used since
installation.
Press the unit’s STATUS key to display checked battery and
sensor voltages, along with the date, time, and firmware version.
Using this key, you may print the fault log for easy
troubleshooting. See Section 6.4.1 “Fault Logs” for details.
Self-Test Modes - The power-up self test has the following
modes:
Comprehensive Test - Performed if the unit has been turned off
for more than 2 hours and takes approximately 20 seconds, that
is, the unit’s full built- in test (BIT). Such timing allows this test
to be done sufficiently to ensure that all the unit’s functions are
tested at reasonable intervals.
Abbreviated Test - Takes only a few seconds. The unit does this
test if it has been in use during the last 2 hours. The
comprehensive test (or BIT) is unnecessary each time the unit is

powered up, so the unit only does an abbreviated test for shortterm power-down/power-up cycles.
2.2.2 Vibrex 2000 Plus
Enhancements
The Vibrex 2000 Plus model represents a significant
performance increase over the Vibrex 2000 (Part Number 135902 and earlier). In addition to all existing Vibrex 2000 benefits
features, and capabilities, the Vibrex 2000 Plus system offers the
following extended capabilities.
An increase in maximum spectrum frequency from 24,000
RPM to 600,000 RPM (10 kHz)
A graphic spectrum viewing mode
An extended balance frequency range from 120 RPM to
30,000 RPM
Support for running up to four propeller balance jobs in
parallel operation (can suspend one then jump out and start
another)
Four times the memory, allowing more data to be saved (1
Mb)
The ability to store balance jobs, adjustments, sensitivities,
spectra, and balance measurements in the instrument’s
memory and archive them on a PC
Storage of firmware in the instrument’s Flash memory,
facilitating software upgrades and enhancements; there is no
longer any need to open the instrument for this purpose

2.2.3 Enhanced Vibrex 2000 Plus
Enhancements
Using the same hardware package as the Vibrex 2000 Plus, the
Enhanced Vibrex 2000 Plus model improves some of the Vibrex
2000 Plus software features as well as adding a completely new
capability to track and balance specific helicopter (version
4.xx+) and fixed-wing aircraft (version 5.xx+) models. These
features are summarized below.
Adds the ability to save and recall Propeller Balance
configurations. Auto-corrected and user-entered balance
coefficients can be renamed and saved for later use.
The FasTrak optical blade tracker is now supported in
addition to the Strobex. The EV2K+ provides the ability
to use preset helicopter FasTrak setups as well as modify
and create new FasTrak configurations.
Adds an extensive new Helicopter Balance capability
(version 4.xx+). A complete set of balance charts for 28
helicopter models and variants are included. These
function as simple “single-plane” balance charts and can
be selected for various components, flight regimes,
change types and measurements. These balance charts
are the same as provided in the advanced VXP balancer.
They can be modified and stored as new configurations.
Adds an extensive new Fixed Wing Balance capability
(version 5.xx+) similar to the EV2K+ Helicopter
