АТТ 9002 Digital Vibration MeterVibration is mechanical oscillations in machines, devices and structures. Its influence on a human organism may be either beneficial or harmful. The effect depends on vibration frequency and intensity АТТ-9002 is a devise designed to measure vibration velocity and acceleration in the frequency range from 10 Hz to 5 kHz. The whole device consists of a sensor with a flexible cable and a gage unit. To start work press the button POWER. To measure velocity set the ACC/VEL switch to the VEL position, to measure acceleration - to the ACC position. To measure root-mean-square value set the RMS/PEAK switch to the RMS position, to measure peak value - to the PEAK position. Measured data appear on a large LC-display. The device has a data record function and a function which enables measured data to stay on the screen. A 3.5 mm RS 232 connector is located on the device upper side near the probe connector. This intercoupler outputs 16-bit data flow for customer applications. The delivery set includes: a device, a measuring probe, a plastic case, a service instruction.
