System Prompts
After you step past the Set Point 2 prompt [`SP2] and the Idle Set Point
prompt [IdSP] to the Operation menus, the Series 988 displays the menu
selection ( [`SYS], [PidA] or [PidB] ) in the upper display and [OPEr] in
the lower display.
The Up-arrow > or Down-arrow key < selects another menu. Press the
Mode key µ to display the first prompt in the lower display and its value
in the upper display. Use the Up-arrow > and Down-arrow < keys to
change the value in the upper display. The new value will not take effect
