You can measure acceleration, velocity, displacement with various physical quantities at the same
time in the vibration level meter. The various quantities are RMS(Root-Mean-Square), Peak, Peak To
Peak, Max and Min.

works when you select accelerator in the transducer. The references of the decibel calculation are
listed in the <Table IV-2-1>.
