B. Setup parameters for sensors
The sensor parameters to be set up are described on P. 2-20 If you
have defined a default sensor for vibration measurements (see p.
2-22), the ‘Sensor Setup’ menu is deactivated.
C. Evaluation parameters for overall value / time waveform meas.
For characteristic overall value measurement tasks, which are mea-
sured according to ISO 10816-3, the corresponding thresholds are
stored in fixed evaluation setups. For all other measurement tasks,
create a user-defined evaluation setup.
• Activate the checkbox in front of the overall value.
• Select the limit value (see below).
• If necessary, change the names of the limit values.
To change the tab, press the '+/-' key or highlight this with the navi-
gation keys.
Enter a description for the evaluation setup:
• Press the MENU button and click on 'Description'. A text field (ini-
tially empty) appears.
• Press the MENU button and click on 'Edit'.
• Enter the descriptive text in the text editor.
• After terminating the text input and closing the text editor, press
the MENU button and click on 'Save'.
D. Parameters for RPM measurement
The RPM should always only be recorded if RPM-synchronous signals
appear in the spectrum, characteristic frequency needs to be updated,
or the frequency axis is scaled in orders (order-based analysis).
In addition to the measurement, you can enter the speed by hand (not
for phase measurement and balancing). If you want to enter the RPM
by hand before a measurement*, proceed as follows:
• Select the ‘RPM measurement’ menu and press the MENU key.
• Click on ‘Edit’ to open the task manager for the RPM task.
• In the ‘Sensor Setup’ menu, set the transducer to: ‘Manual entry’.

only) can be found in the next chapter
