7.13. Vibshape
The Vibshape™ function is mainly used to collect
data for computer animation of machinery
vibrations.
From Main menu select Measure and Vibshape .
The Vibshape™ function can also be used to measure coast-up on RPM controlled machines
like steam turbines and frequency controlled motors. Because the instrument saves the
vibration, phase and speed of each measurement many transducers (one by one) can be
measured at the same speed
To use the Vibshape™ function the instrument must have a
signal on the RPM input. This signal is usually coming from
the RPM transducer in the same way as with balancing, but
can also come from another source like a signal generator
driving a vibrator.

7.13.1. Vibshape Settings
When you select New the program displays the settings
menu. The following parameters can be set:

Measurement type : mV, Acceleration, Velocity or
Displacement

Detection type : How the amplitude of the frequency is calculated. RMS, Peak or
Peak- Peak.

Frequency unit : Hz or CPM

Multiple 1 value : Number of times to multiply vibration and angle to the reference
signal (Ext. Tacho)

Multiple 2 (Enabled, Disabled) If disabled you will create a list with only Multiple 1
values.

Multiple 2 value: The instrument can measure two values from the same transducer
at the same time. By entering for example 1 after Multiple 1 value and 3 after
Multiple 2 value the instrument will measure the vibration and angle (phase) of one
and three times the shaft speed or reference input.
