Extended diagnostic functions
OI/FEX300/FEX500-EN FEX300, FEX500 133
8.2 Checking the grounding
This function allows you to check the electrical grounding of the device.
Important (Notice)
• While the check is in progress, no flow measurement can take place.
• The measuring tube must be full.
• No flow must occur in the flowmeter sensor.
• The device must not be provided with a preamplifier.

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.
