Averages

Averaging the 'out of balance' values can increase the accuracy of
your measurements, allowing the instrument to make more precise
recommendations for the size and placement of balance weights. A
higher number of averages produces more accurate measurements,
but lengthens the recording time accordingly.

Machine Information

Entering machine information is optional. It allows you to specify
some of the physical properties of the machine being balanced.

Rotor Weight, Diameter and Speed

Entering the rotor's weight, diameter and speed helps the instrument
to calculate the appropriate size and placement of trial weights
based on your machine's physical properties. The aim is to calculate
a trial weight which will cause a significant change from the initial
reading.
From the Balance Setup Menu press
•
Information and use the on-screen options to enter your
values. If you need to enter a decimal point press
If you need to change a measurement unit e.g. for rotor
•
weight or diameter, return to the Balance Setup Menu and
press
then press
After you take the initial reading the instrument will display the
suggested trial weight mass in the upper left of the screen.
Note: In Manual input mode and without a tachometer connected no
suggested angle and weight will be provided by the instrument.
