On the display, the parameters are organized in such a way that a maximum of
information is obtained without having to scroll down. The user may customize the display
to his particular needs. To do this, follow the steps given below:
· Select the measured parameter that has to be moved
· Press
· Press
· Once the selected parameter is located at the desired position in the list, press
