installation mode, called "Slave_InStALL ". To select a menu option, the alternate button
must be held down for longer than 2s. The final value in this display mode is the end-of-list

If the time limit after the last touch on the button has been reached (this can be
parameterized in a range from 1min to 2h) or the alternate button has been kept depressed
for not less than 5 s, the meter will automatically switch over to the operating display.
