The system will default to the last window settings and automatically display them at next power on. 

1.4. Keypad Functions

This keypad is dual function keypad: 
1. When separately pressed, is shortcut function, referring to "2. Quickly set menu instructions ";

2. Press

and  Number  key,  is  Menu  key,  referring  to"6.Menu  Window  Description".Follow  these 

guidelines when using the Flowmeter keypad (Refer to Keypad Figure): 

  And 

To input numbers. 

Backspace or delete characters to the left. 

  And 

  Return  to  the  last  menu  or  to 

open  the  next  menu.  Acts  as  "+"  and  "-"  functions 

when entering numbers. 

  Select a menu. Press this key first, input two 

menu numbers and then enter the selected menu. For 

example  ,to  input  a  pipe  outside  diameter,  press 

keys, where "11" is the window 

ID to display the parameter for pipe outside diameter. 

1.5. Keypad Operation 

The flow meter adopts the window software design to consolidate or subdivide all of the parameters entered, the 

instrument setup and measurement result displays into more than 100 independent windows. The operator can 

input parameters, modify settings or display measurement results by "visiting" a specific window. These windows 

are arranged by 2-digit serial numbers (including "+" sign) from 00~99, then to +0, +1, etc. Each window serial 

number, or so-called window ID code, has a defined meaning. For example, Window M11 indicates the parameter 

input for pipe outside diameter, while Window M25 indicates the mounting spacing between the transducers, etc. 

(Refer

Windows Display Explanations). 

The  keypad  shortcut  to  visit  a  specific  window  is  to  press  the 

key  at  any  time,  then  input  the  2-digit 

window ID code. For example, to input or check the pipe outside diameter, just press the 

keys for window ID code 11. 

Another  method  to  visit  a  particular  window  is  to  press 

and 

keys  to  scroll  the  screen.  For 

example,  if  the  current  window  ID  code  is  M02,  press 

key  to  enter  Window  M01,  press  the 

button again to enter Window M00; then, press the 

  key to back Window M01, and press the 

  key 

again to enter Window M02. 
Windows are separated into three types: (1) Data Type, such as M11, M12; (2) Option Type, such as M14; (3) 

Pure Display Type, such as M01, M00. 
You  can  check  the  corresponding  parameters  by  visiting  the  Data  Type  Windows.  If  you  want  to  modify  the 
parameters, input the digits and press 

or press 

first, input the digits then press 

again to 

confirm.
