1.5.3 Basic Functions
The commands below set the basic functions of the 338
transmitter during
QuickSet Configuration.

unknown, and the liquid is at the proper height in
the tank.
1.5.4 Setting
QuickSet Configuration
Parameters
The table on page 8 shows how to set all six of the
QuickSet Configuration
parameters.
NOTE: Current output can also be programmed for inverted
operation: 4 mA = 100% (Full), 20 mA = 0% (Empty)
NOTE: If a parameter value is not accepted by the LCD module, the
existing parameter value will keep blinking. This is due to:
1. The value is out of range (example would be trying to
enter a range value larger than 20.00 feet)
2. The parameter value is not valid for this screen
