Introduction
Model 394C06 Handheld Shaker is a small, handy, completely self-contained vibration reference source. It is
intended for rapid checking of vibration measurement, monitoring and recording systems using piezoelectric
accelerometers, as well as other types of vibration transducers having a maximum weight of 210 grams.

Description
Model 394C06 permits accurate adjustment of measuring instrumentation to output a standard acceleration level
of 1 g RMS or 1 g peak, with automatic internal compensation for the applied mass. The reference signal may
also be used for velocity and displacement, at 10 mms

peak and 10 µm RMS or 10 µm peak-
to-peak respectively. To change between RMS and peak, depress the corresponding side of the rocker switch in
the options cavity of the shaker. For example, to choose RMS, depress the left side of the rocker switch as
illustrated in
Figure 1
.
Model 394C06 also provides quick, single sensor validation in complex measurement systems. Confirmation of
proper function through the full measurement chain from the sensor, cable(s), signal conditioning through to the
data acquisition instrumentation, is extremely useful when configuring large sensor arrays.
