Outline
The VM-83 is a vibration meter designed for measurement and evaluation
of vibrations, using a piezoelectric accelerometer or a servo accelerometer.
It provides four types of input connectors and allows selection of accelera-
tion, velocity, and displacement measurement. With the optional servo ac-
celerometer, even very low frequency vibrations in the range of 0.1 to 1 Hz
can be measured, something that is very hard to achieve with conventional
piezoelectric accelerometers.
Display characteristics can be switched to rms, equivalent peak, and equiva-
lent peak-to-peak. Peak hold and max. hold functions are also available, and
a comparator with level evaluation output is also available.
AC output, DC output, and a serial interface are provided as standard equipment.
The unit uses a box-type design that makes it easily portable, and it can be
powered from the AC adapter or from batteries.
