POINTs.
As a general setup guideline, in order to be triggered
properly and to read phase properly, check the
following:
•
Set the Microlog to accept an external
tachometer trigger signal. The strobe light will
provide this signal.
•
Set the frequency range for order analysis (10
orders full scale works best). This ensures the
1X frequency will be centered in the 1X (first
order) filter, which is necessary for repeatable
phase measurements.
•
Set the Microlog to display averaged spectrum
and phase data (4 or 8 averages).
•
Set transducer power to On.
•
Connect the proper interface cable between the
strobe and the Microlog. See wiring diagram to
build the cable. The Input and Output jacks are
located on the left side of the strobe. Connect
the vibration transducer (this may be a separate
cable or an integral cable) to the strobe cable.

For the AX Series Microlog, strobe
light use requires accessory cables
CMAC 5404 (input cable) and CMAC
5406 (output cable). Reference your
AX Series Microlog User Manual for
connection details.

For the GX / MX Series Microlog, you
will need to use the SKF Audio
