KEYPAD PROGRAMMING
A meter ordered with a keypad can be configured through the keypad interface or by using the Windows® compatible
software utility. Units without a keypad can only be configured using the software utility. See SOFTWARE UTILITY of this
manual for software details. Of the two methods of configuration, the software utility provides more advanced features and
offers the ability to store and transfer meter configurations between like flow meters. All entries are saved in non-volatile
FLASH memory and will be retained indefinitely in the event of power loss.
