Quick Reference Guide

This guide provides a quick-start reference for the Vibrex 2000 and

Vibrex 2000 Plus Digital Dynamic Balancer systems. The term Vibrex unit

refers to both systems.

Propeller Balance

Propeller Balance, Run No. 1

• Install the photocell, velocimeter(s), and reflective tape on the propeller

to be balanced.

• Turn on the Vibrex unit.

• Select Propeller Balance from the Main Menu screen.

• Ensure the propeller input is plugged into channel No. 1 and A and any

other propeller or velocimeter in the other channel. Press START.

• Select the engine horsepower, then press START.

• Operate the propeller at the desired balance RPM. When the RPM is

steady, press START.

• When the Vibrex unit has finished collecting data, press START.

• If the reading is not acceptable (greater than 0.2 IPS), press

START.

• Observe displayed note then press START.

• Implement the solution and power off the Vibrex unit.

Propeller Balance, After Run No. 1

• Turn on the Vibrex unit.

• Select Propeller Balance from the Main Menu screen.

•Vibrex 2000 Plus Only - Select Continue Current Session.

• Edit the solution if it is different from the solution done earlier then

press START.

Quick Reference Guide

xChadwick-Helmuth Company, Inc.

• Operate the propeller at the same RPM as done in Run No. 1. When

the RPM is steady, press START.

• When the Vibrex unit has finished collecting data, press START.

• Continue making adjustments until the propeller yields the desired

IPS level, then press DONE from the Prop Balance Quality screen.

Spectrum Analysis

• Install the velocimeter in the desired location for measurement.

• Power up the Vibrex unit.

•PresstheSPECTRUM ANALYSIS context key.

• Select the velocimeter channel and azimuth sensor channel (if used).

• Select the RPM range of interest.

• Operate the aircraft at the desired condition for taking measurements,

then press START.

•Press

START to save.

Balance Reading

• Install the velocimeters and photocell, as desired, for the aircraft to be

balanced.

• Power up the Vibrex unit.

•PresstheTRACK & BALANCE context key from the Main Menu

screen.

• Operate the aircraft in the desired condition.

• Press the desired channel to take measurement input.

•Press

START to save.

Strobex Track

• Install the Photocell (or magnetic pickup), Strobex, and retro-

reflective targets to be viewed.

• Power up the Vibrex unit.
