The only parameter you need to set is the frequency of interest - this
is typically the machine running speed.
• Press
to enter the RPM then to continue.
• Press
to begin measuring both channels.
The instrument will perform a spectral peak search at the entered
frequency (machine speed or any frequency of interest) on the
channel 1 signal. The frequency of the actual peak is displayed at
the top of the screen, always in RPM. The instrument then looks at
exactly the same frequency on channel 2 and displays the phase
difference Ø
2
- Ø
1
(CH2 - CH1). The instrument also displays the
amplitudes of both channels at that peak frequency.
• To change the target frequency (the peak of interest) use
or to adjust the value in 50 RPM increments.
Note: This measurement cannot be saved.
Setting your own parameters
Option
Custom Setup allows you to customize this menu to use
your own settings instead of the factory defaults. See Custom Setups
