Operation as an analyser

When operating as an analyser the task is the acquisition of

measurement in the following modes

•

Overall Vibration / BCU

•

Spectrum / Cepstrum

•

Envelope Analysis / BCS

•

CPB - spectrum

•

Process-values

•

Tracking Analysis

•

Keyboard Input

Selection of the measurement mode is done at the

VIBROTEST 60 main menu.

Operational modes

SELECT The item on the menu highlighted by the cursor will

be selected.

INFO

Switch to the information display menu.

SETUP Opens the menu „System Setup„
REPORT Opens the Reports selection list.

Measurement task configuration

The VIBROTEST 60 must be configured for the current

measurement task. The configuration menu is selected using

the »SETUP« button

after

the operating mode has been

selected.

Two-channel measurement acquisition

The VIBROTEST 60 can acquire measurements at two

channels simultaneously. Two-channel measurement acqui-

sition is activated in the „System Setup„ under „Channels„. The

measurement display is switched between the two channels

using the button »1/2«.
