Frequently Asked Questions
Does my StroboClip HDC require calibration?
Unlike more modern Peterson strobes, legacy models such as the Peterson 400, 420, 450 and 700 do require occasional calibration.
If you require service, please open a support ticket and return the tuner for repair.

What is the battery life of StroboClip HDC?
The colors red, green, and blue use only one LED driver and therefore require less power allowing for longer use before depleting the battery.
White uses all three LED drivers at full power, using the most amount of battery power and will reduce the amount of tuning time available.
Brightness values will also affect the battery life. Brightness may be set via the Configuration Tool in Peterson Connect.

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.

I often tune my acoustic instrument in a loud environment. What's available to help with that?
A Peterson TP-3 clip-on tuning pickup is a very versatile device with a 1/4" connector that can be clipped onto any portion of the instrument that vibrates, such as the headstock of a guitar or the bell or lead pipe of a horn.
A Peterson Pitch Grabber Mobile Tuning Clip utilizes a 1/8" connector for use in mobile phones or tablets with software tuners.
For instruments with a flat resonating surface, you can use a suction cup tuning pickup to reduce ambient noise interference.
