Introduction to the SKF Strobe Light
Overview
Strobe Light 1 - 3
User Manual
Overview
The Strobe Light is a truly portable, battery-operated
stroboscope suited for a wide range of industrial,
institutional, and educational applications, and is able
to interface with the SKF Microlog. Several interface
cables are available. Sturdy and compact, the strobe
can be operated anywhere in the plant or field to
permit visual inspection (freeze motion), phase shift
studies, and digital measurement of rotary,
reciprocating, or linear motions of various equipment
while it is in operation.
The Strobe Light has a special “tuning” circuit that
allows it to track vibration transducer (accelerometer)
signals. This capability makes it different from
general-purpose strobe lights. It also has a Narrow
and Wide Bandwidth filter selection to discriminate
fundamentals from harmonics. The Narrow
Bandwidth filter limits the influence of harmonics
around the selected frequency, providing a more
stable phase reading.
The Strobe Light requires an input signal to
synchronize the flash rate with an external source,
typically a vibration transducer in the tracking mode
or optical pickup in the external mode. This signal is
applied, using a special cable, to the Input (
pointing into socket) jack connector on the side of the
strobe light. The Strobe Light generates a tachometer
signal that is on the Output (pointing away from
socket) jack. Information about the use of these
signals is given in other sections of this manual.
Special adapter cables are available to work with your
Microlog.

The Strobe Light is ideally suited for:
Balancing
Inspection of High Speed Rotating Parts
Motion Analyses, or Phase Shift Measurement
Over speed Trip Tests
Online coupling Inspections
RPM / RPS Measurements
All applications suited to a general purpose,
phase shifting stroboscope
The Strobe Light can also be used as a highly
accurate, remote electronic digital tachometer for
direct measurement of RPM / RPS (speed) without
special reflective tape or markings. RPM results are
updated and displayed approximately every half
second on the LCD display.
Display Panel / Definition of Buttons
Display Panel
The display panel consists of a backlit liquid crystal
display with six numeric digits on top and five
alphanumeric digits on the bottom, which indicate
modes, flash rates, etc.

Multiplies flash rate by 2 times
ALT Function - Starts Menu
Hold when powering up to show all segments, then
Rev # and display test
Divides flash rate by 2
Hold when powering up to reset factory defaults
In Internal/External Mode - Toggles display between
RPM and RPS. In External Phase or Time Delay Mode
- Cycles display through RPM, RPS, Phase and Time.
In Auto Mode - Cycles display through RPM, RPS,
VRPM and VRPS.
ALT Function - Toggles Tach Mode (flashing) on/off
Manually cycle through Internal, External, Wide Lock,
and Narrow Lock Modes
ALT Function - Memory - Reads and Stores 9 preset
flash rates
Activates Alternate Function for buttons (lower
section) and knob
The ALT FUNCTION button toggles ALT. in the
display. When ALT. is displayed, the buttons will
perform their secondary function listed in the lower
section of each button. It also changes how the tuning
knob works.
In Internal Mode, toggles between normal flash rate
adjust and “phase” delay adjust
In External and Lock Modes, cycles through External
only (no delay), Phase, Time and Auto (VRPM)
ALT Function – In Lock Mode, toggles Filter tracking
