The Type IET Labs GenRad 1557-A Vibration Calibrator is a small, battery-operated, self-energized shaker. A transistorized electromechanical oscillator is mounted in a cylindrical shaker by means of small leaf springs. The calibrator will vibrate, at a 1-g acceleration level, any pickup with a total mass of 300 grams or less, and can therefore be used to calibrate most of the popular accelerometers and vibration pickups in use today.
•Calibration of vibration pickups, meters
