Chapter 4 - Off Route Analysis with the dataPAC
Using a Strobe to Collect Phase/Magnitude/Speed Measurements
dataPAC 1500 V5 only
The dataPAC 1500 V5 allows you to use a strobe light to collect phase measurements so
that you can compare two phase measurements, such as the opposite ends of a shaft.
Measuring phase with a strobe is only meaningful if you have another phase measurement
to compare it to. Set up the parameters using Strobe for the Trigger Select. This screen
shows the set up.
1.
After setting up the measurement, press <STORE>.
2.
Press the button on the strobe and aim it at the rotating machinery. You can keep the
strobe in the on position by pressing the small button on the side of the trigger.
3.
Press <F2> (Auto Speed) to get an estimation of the running speed from the transducer.
If you do not have a high 1X running speed peak for the item you are viewing with the
strobe, the Auto Speed function may not be able to detect the running speed.
4.
Use the up and down arrow keys on the dataPAC to adjust the strobe speed so that it
matches the running speed of the machine. Lock the marker at one position, such as the
12 o’clock position. Use the 1/2X Speed and 2X Speed softkeys to make sure that you
have the correct flash rate. If you still see one mark when you press 1/2 Speed, the
correct flash rate may be half as slow as your current speed.
5.
Press <STORE> to continue. This action measures the phase shift. If you are collecting
a comparative measurement, stop the mark at the same spot as the previous
measurement. If you are comparing two measurements, such as the ends of a shaft, be
sure to lock each at the same position to get relative phase.
6.
Press <STORE> to store the measurement of phase, magnitude, and speed.
