The user interface of this flow meter comprises about 100 different menu windows that are
numbered by M00, M01, M02 … M99.
There are 2 methods to enter certain menu window:
(1) Direct going/entering. The user can press the MENU key followed by two-digit number
keys. For example, the menu window M11 is for the entering of pipe outer diameter. The
display will go to the M11 menu window after the user presses MENU 1 1 .
(2) Pressing
▲
/+ and
▼
/- keys. Each time of the
▲
/+ key pressing will proceed to the
Lower - numbered menu window. For example, if the current window is on M12, the display
will go to the number M11 window after pressing the
▲
/+ key.
There are three different types of menu windows:
(1) Menu windows for number entering, like M11 for the entering of pipe outer diameter.
(2) Menu windows for option selection/selecting options, like M14 for the selection of pipe
materials.
(3) Displaying windows only, like M00 to display Velocity, Flow Rate etc.
For number entering windows, the user can directly press the starting digit key when the
user is going to modify the value. For example, when the current window is on M11, and the
user is going to enter 219.2345 as the pipe outer diameter, the user can get the numbers
entered by pressing the following serial keys: 2 1 9 . 2 3 4 5 ENT.
For the option selection windows, the user should first press the ENT key to a selection
modification mode and then select the relevant options by pressing the
▲

or the digit keys to select the option with a number antecedent to the option. In the end, the
ENT key must be pressed to make the selection. For example, with menu window M14 for
the selection of pipe material selection, (the MENU 1 4 should be pressed first to
enter this menu window if the current menu window is on a different window. The pipe
material is stainless steel which has a number “1” antecedent to “stainless steel” on the

then either make the selection by pressing the
▲
