NOTE: If no push buttons are pressed for 30 minutes, the transmitter
will automatically return to the measurement mode, and oper-
ate with the parameters entered during the last completed
programming.
NOTE: The Range, 4 mA, and 20 mA values shown below can be
entered manually, or by automatic entry using the "Get Level"
feature. Because the automatic entry involves moving the
liquid level to the exact 4 mA point, 20 mA point, and Range
values, the manual entry is the preferred configuration mode.
