• In data display mode, it scrolls through the display
pages.
• In programming mode, it scrolls through the menu
items and allows changing a selected digit when
entering numbers.
The SELECT/ENTER button normally operates once it’s
released. The button function changes depending on the time
the button is pressed:
• In data display mode, when pressed briefly and
released, it scrolls through the display views; a long
press for more than 5 seconds switches to
programming mode.
• In programming mode, when pressed briefly and
released, it moves from one menu item to another; a
long press for one second selects a highlighted menu
item allowing to enter a submenu or to store a
changed item.
In data display mode, when the SCROLL and
SELECT/ENTER buttons are briefly pressed together and
then released, the current display returns to the start page;
in some pages, an extended press for more than 5 seconds is
used as a “shortcut” for immediate entering a specific
programming menu.
