One Plane Balancing with a Strobe Light
This section discusses the procedure for balancing a machine in one plane using the
dataPAC and an attached strobe light. The entire procedure is divided into parts based on
when you start and stop the machine. You must complete the entire procedure until the
vibration level has been reduced enough for your needs.
Using the Strobe dB+
The dataPAC Strobe dB+ is the newest strobe available from Entek. It synthesizes all
signals digitally, in small, very precise steps. These signals are derived from a stable crystal
oscillator.
To use the strobe by itself, turn the knob counter-clockwise to increase the flash rate and
clockwise to decrease it. The knob is velocity sensitive. Turn the knob slowly to have each
“click” equal to 0.1 FPM. Turning the knob more quickly will adjust the FPM by larger
steps. When adjusting flash rate, quickly turn the knob (or use the x2 or ÷2 buttons) to
coarsely change the FPM. Then slowly turn the knob for fine adjustments. Turn slower still
for very fine adjustments.
To turn on the stroboscope, depress the trigger. You can lock the trigger in position using
the side locking button. Push the trigger as far as it will go, and then press the locking
button. Release the trigger with the lock on and the trigger is held in place. To release the
lock, simply depress the trigger and release.
The back panel on the Strobe dB+ consists of a backlighted liquid crystal display with six
alphanumeric digits which indicate modes, flash rates, and other items. Below the six digits
are five small triangles which indicate the present mode or value currently indicated - Ext
(External mode), TACH, ALT function, FPS/HZ (Flashes Per Second), and FPM/RPM
(Flashes Per Minute).
The External triangle is on whenever the strobe is in the external mode. The external mode
means an external signal, such as the dataPAC, is plugged into the external input jack. The
FPM triangle is on when the display is displaying Flashes Per Minute. The FPS triangle is
on when the display is displaying Flashes Per Second or Hertz (Hz). (FPS = FPM ÷ 60)
