Position the power supply where it is easily accessible so that the meter can be separated from the power
at any time.
Check the power supply regularly. If the power supply is damaged it must be promptly replaced by an
undamaged unit.
Use only the power supply VER05US050-JA (input 100-240 V~; 50/60 Hz; 0.18 A; output 5 V DC;
1 A max.; class II)!

1) Sensor connection
2) USB port
3) Main Supply
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 (Interface HMG USB) to transfer data from the meter to the PC. This cable is not
included in the delivery and must be purchased separately (
chapter „Accessories”).
