On the front of the meter, there are special connectors to connect the sensor and a USB interface
cable.
Use only the sensors, sensor cables and interface cables recommended by the manufacturer.
The notes and statements in the respective user manuals and data sheets apply to the use of the
sensors and fittings. As the measuring system is intended for the measuring of analysis parameters
you must keep in mind that the sensors must be calibrated and maintained regularly.
The measuring input must be free of potentials and must not be connected to power conducting
potentials. All inputs must only be operated with the proper sensors. The direct connection of different
signals is prohibited!
In order to protect the connections from the ingression of moisture and the resulting corrosion,
you should always leave the sensor plugged into the meter.
Please note the switches when connecting to other devices (e.g. via USB interface).
Internal connections in other devices (e.g. connecting GND to earth) can lead to impermissible voltage
potentials that can impair the function of the meter itself or other devices or can even destroy them.
Use only interface cable Z 613 to transfer data from the meter to the PC. This cable is not included
in the delivery and must be purchased separately ( chapter 12 Accessories).
