The MTN/VM110 Vibration Meter is a battery powered, portable instrument designed to operate with a constant current type accelerometer (10mV/g sensitivity) to make vibration measurements simple and convenient.
Both RMS and Peak detection of acceleration, velocity and displacement can be made in three ranges. A switched low pass filter for the reduction of wide band noise is provided.
An AC output via a ‘D’ type output socket allows the connection of additional filters or a signal analyser. A DC output is also provided to drive a chart recorder.

Accuracy (10 mV/g Input)
Figures are for the VM110 only, since input transducers will affect the overall system accuracy. All readings are 1 digit added to the following full-scale errors.
Acc. 1.5% RMS; 3% Peak: Vel 2.5% RMS; 4% Peak: Dis 3.5% RMS; 5% Peak (9% at 10kHz)
Equivalent Input Noise
The equivalent input noise is the lowest measurable signal level in the range due to internally generated electrical noise.
