How to fix grounding problems in Nortek Vectrino?
Grounding issues often arise near man-made structures but are less common in open field environments. To mitigate these problems, try coiling your power and data cables tightly and elevating them off the floor, for example, by placing them on a chair. Alternatively, using batteries to power the internal recorder can eliminate potential grounding problems, even indoors.
What to do if Nortek Vectrino is not detected on the serial port?
If the Vectrino isn't detected, the baud rates between the Vectrino and the terminal program might be mismatched. Try different baud rates, using Online > Stop Data Collection to autodetect the baud rate. If problems persist, test with a different computer. Verify the serial port and cable with a serial loop-back test. If the cable passes but the instrument remains unresponsive, it might be a null modem cable; try a different cable or a null-modem adapter.
What to do if there is too little backscatter with Nortek Vectrino Measuring Instruments?
Ensure the signal level (H) reaches at least 70 counts.
What to do if a Nortek Measuring Instrument has a weak receive transducer?
If one receiver differs from the others by more than 20 counts, clean the receive transducer to ensure it is not blocked. If the problem persists, return the Vectrino to the factory.
