Once the grounding check has been started, the frequency
range up to 250 Hz is measured. The four most intensive
frequencies of the spectrum are shown at the right of the
display.
The corresponding amplitudes and the power spectrum
over the frequency range can be called up for display using
the following parameters.

The measured values indicate possible disturbances of the device's grounding line at the time
of the test.
No or minor disturbance:
• When the power spectrum is below 1000.
• When the four measured amplitude values are above 10.
Check the device grounding (!):
• When the power spectrum is above 1000.
• When the four measured amplitude values are above 10.
