7.9.1. Coast Up Measurement Settings
When you select Coast Up from measurements menu the
instrument will display the settings menu.
In this menu, the following parameters can be set:

Measurement type (Acceleration, Velocity,
Displacement or mV)

Show unit (depending on the above selection)

Detection (RMS, Peak or Peak- Peak)

Maximum Speed- Maximum speed when the measurement will be stopped. This
may be the nominal speed of the machine. The limit is 60 000 CPM

Start Speed- Minimum start speed is 90 CPM

Speed interval- The minimum speed change to store a new measurement point.
Disabled means as fast as possible or about 6 CPM (0,1 Hz)

Frequency Unit (Hz or CPM).
By pressing (F4), all the parameters will be set to a default value.
The function keys have the following shortcuts:

(F1)–enters Select Sensor menu

(F2) – enters Transducer Settings menu
In addition to the above settings the instrument will automatically disable the energy

Press (OK) to start measurement. Press (ESC) to exit.
7.9.2. Measure Coast Up
When you enter the measurement, the Instrument displays the measurement parameters
and waits for a start confirmation (It displays "Press
(OK) to start measurement").
The screen is divided into two panels:
On the left panel of the screen are presented:

Vibration sensors used

Speed transducer selected

Start speed

Maximum speed (when measurement will be
stopped)

End speed (when stopped)

Speed interval

Actual speed measured (only during measurement)

Measured points (the number is displayed after the measurement is finished)
On the right side screen appears the current measurements for one of the measured
channels in two diagrams, each of them having the speed on X-axis. The upper diagram
shows the Amplitude on Y-axis, in the selected measuring unit. The bottom diagram shows
