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 independent windows. The operator can input parameters,
modify settings or display measurement results by "visiting" a specific menu window. Each window serial number,
or so-called window ID code, has a defined meaning. For example, Window M10 indicates the parameter input for
pipe outside diameter, while Window M14 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 10. Use and to switch.
Another method to visit a particular window is to press and to scroll the screen.
You can check the corresponding parameters by visiting the Data Type Windows. If you want to modify the
parameters, press first, input the digits then press again to confirm.
Attention
Generally, press
Enter
key first if operator wants to enter "modify" status. If the "modify" is still not
possible even after pressing the
Enter
key, it means that system is locked by a password. To
"Unlock" it, select "Unlock" in Window M54 and enter the original password.
