Section 3: Onsite Analysis - Measurement Menu

The only parameter you need to set is the Fmax value. This can be
done in two ways:
¾ Press
to display the Machine Running Speed Menu
then use the number keys to enter an RPM value. The
Fmax will be set to 10 x the RPM (or rounded up to the
closest value).
OR
Press
to display the Set Fmax Menu and use or
to select a value.
Once the Fmax is set, select the machine, point and
direction in which the sequence of measurements will be
stored.
Recommendations
A large number of recordings will be created so we recommended
you create a new 'point' for each new coast-down or run-up
measurement to clearly separate each set of recordings.
For machines with a slow coast down or run up, e.g. more than one
minute, we recommend that you add a few seconds extra delay
between recordings (press
then enter the number of seconds
required).
The use of a tachometer is also recommended but not essential. It
obtains an RPM reading for every measurement, which aids
interpretation.
Taking a measurement
Press
to begin the recording sequence.
After the first spectrum has been recorded, switch off the
machine (or begin ramping its speed up or down).
Once the machine has stopped rotating (or its speed has
been fully adjusted) press
