The flowmeter user interface comprises about 100 independent menu windows that are numbered
by M00, M01, M02,…,M99, M+0, M+1, etc.
There are two methods to visit a menu window:
(1) Direct jump in. Simply press the MENU key followed by a 2-digit number. For example, if
user wants to visit menu window M11 for pipe outer diameter, press
the following three keys consecutively, MENU [1][1]
(2)Press the [#/-] or [$/+] key. Each time of the [$/+] key pressing will lead to the
lower-numbered menu window. For example, if the current window is on M12, the display will go
to window M11 after the [$/+] key is pressed once.
User doesn’t need to remember all the menu windows. Just remember the most commonly used
window numbers and the approximate window number of some uncommonly used windows
