06 07 NIVOTESTER RTS For Water / Foam Tanks (5 LEDs) Operating Principle The NIVOTESTER RTS operates based on the conductance of the measured liquids. The electrodes are placed at each quarter length of the probe. The LED indicator (ultra-bright LED) signals the level of the liquid. The red LED indicates that the liquid level has reached less than 25%. As an additional option, an external device (such as a buzzer or siren) can be controlled by a relay output pin on the indicator unit. The indicator is able to communicate with the other displays (Remote Indicators) via the 1-wire datalink. The complete measuring equipment NIVOTESTER RTS consists of the: • indicator IN04 which displays the level of the liquid, • the suitable probe, • the 5-wire probe cable with the connector plug.
