The measured values indicate possible disturbances to the earthing line of the device 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 earthing (!):
• When the power spectrum is above 1000
• When the four measured amplitude values are above 10

Current power spectrum.
Display the four highest amplitudes in the power
spectrum.
48. Use or
49. Use to start the "Grounding Check" function.
Once the earthing 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.
