of the switch, the LCD will display a new parameter (Figure A.4). Parameters will appear in the order specified
by the user when he configured the display. If the user does not press the button to manually advance to the
next parameter, each parameter will be displayed for 30 seconds before the LCD resumes its automatic scroll.

mode, the LCD automatically displays the daily log value from the previous day, which is marked by an index
value of “01.”
