FAST, ACCURATE TENSION READINGS
Testing tension with a spring tester requires
muscle, a piece of string and at least three hands!
The Sonic Tension Meter works on the theory that
belts, like strings, vibrate at a particular natural
frequency based on mass and span length. The
meter converts this frequency into a measure-ment
of tension.

To test tension:

1. Enter belt mass constant, belt width & span
    length into meter.
2. Hold meter to belt span, then strum belt to
    make it vibrate. The meter will measure the
    vibration and convert into belt tension.

Features:

• Output reading measurable in hertz, pounds,
   kilograms and newtons.
• Frequency range from 10-5000 hertz.
• Variable frequency range filters.
• Auto gain control automatically adjusts meter
   sensitivity.
• 20 memory registers for belt constants.
