Voltage measurement

When connecting IP voltmeter to other devices, it's important to consider whether to use a common ground or a separate ground. A common ground means that all devices in the system share the same ground reference. This reduce the risk of ground loops, which can cause noise and interference in the signals.

A separate ground means that each device in the system has its own ground reference. This can help prevent ground faults but can also increase the risk of ground loops and signal interference.

Measured objects can be connected separately or with common ground. The input circuits of the board are designed in such a way that it is possible to measure both cases: with a common ground or completely separate measured objects.
