What are the three cable clamps and electrical bonding needed for?
When used in a rough environment or with long sensor cables (5m and more), interferences can cause an inaccurate and unstable reading.
This can be remedied by using shielded cables. However, the cable shields must also end somewhere and this is where the electrical bonding option for the myDatalogEasy IoT comes into play. Note that in order to avoid earth loops, the shield should be connected on one side – preferably always to the power supply unit, the myDatalogEasy IoT. In addition, the protection against overvoltage caused by lightning is considerably improved.
