7. P0 – Lockout Code All Models
This feature provides security in the M2110P. 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. Once a lockout code is entered, the gauge will prompt for the lockout code before allowing any
changes (similar to a “password”). Changes include Engineering Unit selection, re-zeroing, or entering
Program Mode.
Following an operator action, if the correct code (password) is not entered when prompted, an error message is
briefly displayed. If the operator action was changing Engineering Units or 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 22), 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.
