9 PROGRAMMABLE REGISTERS
9.1 P0 – LOCKOUT CODE
This feature provides security in the Smart Gauge. It is designed to prevent unauthorized personnel from tampering
with or inadvertently changing the configuration of the gauge. The lockout is controlled by a 2-digit setting in the
P0 register. If the lockout code is active, the gauge will prompt for the lockout code before allowing any changes to
register value. If the correct code is not entered when prompted, an error message will be displayed. If the operator
action was to re-zero the gauge, the gauge will simply return to normal Measure Mode operation, without accepting
any change. If the operator action was entering Program Mode, the gauge will enter a “view-only” status (see page
25), denoted by the PRGM indicator flashing.
In Program Mode (and during lockout code prompting), the register value is shown as “L xx” to assist in
identifying the register. The “L ” indicates “Lockout”, and “xx” will consist of the current value.

9.2 P1 – SHUTOFF TIMER
This register sets the automatic shutoff time. The Battery model will automatically shutoff if there is no keypad
activity for this length of time. This feature can be disabled by selecting zero in the P1 register. This will allow the
gauge to remain on until the ON/OFF key is pressed. Please note that usable battery life will be reduced if the unit
remains powered even when not in use. During programming, the choices found in the register correspond to the
actual time-out values, in minutes.
