Figure 4.6. Connection of sensors:

a)  4-wires circuit;  b)  3-wires circuit; b)  2-wires circuit;   

The connection circuit should not be changed while unit is powered.  Every change 

of   connection  while  the   unit   is   powered   causes   measurement   errors   by  several 

seconds after change.

     MAINTENANCE

 

 

The unit does not have any internal replaceable or adjustable components available to 

the user. Pay attention to the ambient temperature in the room where the unit is operating. 

Excessively high temperatures cause faster ageing of the internal components and shorten the 

fault-free time of unit operation. 

In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with 

small amount of detergent or in the case of more significant contamination ethyl or isopropyl 

alcohol. 

Using any other agents can cause permanent damage to the housing.

Product marked with this symbol should not be placed in municipal waste. Please 

check local regulations for disposal and electronic products.
