Chapter 2 How to Enter Data
Several methods of entering data are available. You can scroll through the menus to reach
the menu item you want, or you can use the direct entry code to access the desired menu
item in a single step. For some data entry menu items you use the arrow keys to select
from a list, while for other data entry items you enter numbers with the keypad.
RS-232 and RS-485 serial ports are provided to support communications with the gauge
via a remote terminal, a PC with terminal emulation software, or a TN Technologies' Hand
Held Terminal.
