Frequency-response and illustration limitations
The acceleration response is printed as 0.5–10 kHz. The lower endpoint does not carry its own unit; this reference does not establish either 0.5 Hz or 0.5 kHz. The illustrated waveform and spectrum are examples and do not supply additional measurement ranges or accuracy figures.
