Weight Orientation; Tach Trigger; Weight Lin Dist - Commtest Instruments vbBalancer Instrument Reference Manual

Reference Mark is used in conjunction with CH Position. The
instrument uses this information to calculate where on the rotor you
should place your trial weights after taking an initial reading.
You need to enter both the Reference Mark Location and the CH
Position so that the instrument can calculate the trial weight angle.
Refer to topic CH Position for more information.
If the Balance Machine Menu is not already displayed press
•
Machine Information from the Balance Setup Menu.
Press
•
tachometer reflective tape to your reference mark then press
If these marks are aligned with each other enter zero.
After you take the initial reading the instrument will display the
suggested trial weight angle in the upper right of the screen.

Weight Orientation

Weight Orientation allows you to choose where to place balance
weights on a rotor, relative to the rotor's direction of rotation.
With rotation (WR) means you choose a reference point then place
your weights forward of that point in the direction of rotation (i.e. in
the same direction as the rotor turns).
Against rotation (AR) means that if the rotor is turning forward then
you place your weights backwards from the reference point (i.e. in
the opposite direction of the rotor's rotation).
Ensure that with the rotor stationary you measure angles in the
direction specified. Do not rotate the rotor in the direction specified.

Tach Trigger

Tach Trigger allows you to specify whether you are using a standard
tachometer or a Keyphasor® if using a vbBalancer+ instrument.

Weight Lin Dist

Weight Lin Dist allows you to specify the measurement units for
linear speed distance, balance weights and rotor weight.
