General-Purpose Vibration Meter [VM-83]
The general-purpose vibration meter VM-83 provides four types of inputs and support for acceleration, velocity and displacement measurement.
Features
- Connectivity for various kinds of accelerometers enables a wide range of vibration measurements
- Comparator function with level evaluation output
- Versatile display characteristics including rms, equivalent peak, equivalent peak-to-peak, maximum value hold, and peak hold
- AC and DC output connectors
- Serial interface for enhanced connectivity
- Data printout capability via serial interface
