Measuring principle
The Nivotester supplies a small amount of alternating current to the measuring point via the signal
line. The cable is connected to the ground probe or the metal vessel and the probe.
The voltage drops if an electrically conductive medium touches the probe. An amplifier circuit in the
Nivotester causes the relays to switch.
