Summary
If velocity and displacement is of particular interest then use at frequencies
above 10 Hz is desirable). During handling/mounting of the sensor for low
frequency (below 10Hz), movement of the sensor/cable will affect the meter
readings and they should not be considered accurate.
Lutron state a
Frequency Range of 10Hz to 1kHz
and a calibration point of
160Hz
in the specification area of the manual. We recommend to have the
anchor point of the cable on the fixture that is being measured (as per following
page). This will allow the cable to move in the same motion as the sensor – and
forces on the sensor and cable will now have a better chance of staying equal,
this is more critical at lower frequencies
