The VC21 is a multi-frequency and multi-amplitude reference shaker. The microprocessor based unit contains an amplitude control loop with a reference accelerometer built into the shaker head.
Its lowest frequency of 15.92 Hz makes it suitable for the calibration of whole-body human vibration meters to ISO 8041 and other low frequency applications like measuring equipment for building vibration.
Operation is very simple by four push-buttons, two for amplitude and two for frequency. A bright OLED display shows frequency and amplitude, the amplitude error in percent and the battery condition.
The strong electrodynamic shaker allows heavy test objects up to 500 grams.
The built-in NiMH accumulator lasts for approximately 5 hours of operation
A cast aluminum enclosure protects the instrument under harsh
field conditions.
