15. Lockout Code Prompt

DESCRIPTION

When a gauge is “locked” for security purposes, it does not allow access to change its operating state
without first providing the lockout code. A gauge is “locked” by entering a lockout code in register P0
(See “STEP BY STEP: P0, LOCKOUT CODE” on page 11).


After pressing a key on a locked gauge for a desired function (ZERO, ENG UNITS, PRGM), “L 00”
will appear on the display, with the first 0 flashing. This is the prompt to enter the lockout code
(similar to a password).

VIEW-ONLY STATUS

If a user attempts to enter Program Mode without providing a correct lockout code (password), the
gauge briefly provides an error message, and then enters a “view-only” status, denoted by the PRGM
indicator flashing. In this mode, all registers (except the lockout code register itself) can be viewed,
but not changed.


In this view-only status, the operator navigates through the registers exactly the same as if
programming the registers. However, the keys that would change a value are simply ignored by the
gauge. Thus, the PRGM/Enter

→ key will open a register normally; the Backspace← key will close

the register, and then return to Measure Mode as expected.
