Frequently Asked Questions
How do I read a strobe display?
Adjust your instrument until the pattern is as close to still as possible. Strobe displays are 'real-time' and extremely precise. They require very fine tuning adjustments to stop the display because the frequency/pitch of any instrument is never totally stable.
You'll quickly learn to read the display, make the most precise adjustments and appreciate the high resolution that only a Peterson provides.
