Taking Measurements - PCB Piezotronics IMI SENSORS 647A01 Installation And Operating Manual

Taking Measurements

When measuring the current output from the unit, use the following formula to calculate the vibration level:
Vibration Output = (Measured Output – 4mA) x (Full Scale Vibration Output /16mA)
