The LCD screen displays current measurements of level, tem-
perature, and volume. During programming, the screen dis-
plays parameters and prompts the user for information.

The four control keys are primarily used to enter parameters and move to differ-
ent programming displays:
• Mode: Used to indicate that you wish to change the parameter displayed on
the screen. For scrolling type menus, Mode will scroll forward through the
available selections. The ± key can be used to scroll backwards through the
available selections. In measurement mode, the Mode key is used to access
Program mode.
• Enter: Used to confirm the parameter on the screen or advance to the next
parameter. In measurement mode, the Enter key is used to initiate a printer
report.
• Fnctn: Used to return to a previous parameter.
NOTE: In measurement mode, the Fnctn key is used as a “shift” key providing
dual functions for each numeric key (0 to 9).
• Clear: Used to clear incorrect numeric entries or to exit from the program-
ming mode screens. In measurement mode, the Clear key is used to acknowl-
edge system alarms and to clear the audible alarm beeper.
