2. If lockout is in-active prompt will be P0
• Increment P# using UP ARROW until P10 is displayed
• Press PRGM/ENTER to access the register value
• Press the UP or DOWN ARROWS to change each digit
• Press PRGM/ENTER to enter each digit
• When the flashing decimal point is displayed, Press the UP or DOWN ARROWS to change the sign.
• Press PRGM/ENTER to enter the value and sign
3. The display shows the exponent value for P10. Press the UP or DOWN ARROWS to change the exponent
digit.
• Press PRGM/ENTER to enter the digit, the decimal point will flash
• Press the UP or DOWN ARROWS to change the sign of the exponent
• Press PRGM/ENTER to enter the exponent value

10 REGISTER SECURITY
10.1 DESCRIPTION
When a gauge is “locked” for security purposes, it does not allow access to register data without first providing the
lockout code. A gauge is “locked” by entering a lockout code into the P0 register. After pressing a key on a locked
gauge for a desired function “L 00” will appear on the display, with the first 0 flashing. This is the prompt to enter
the lockout code.
10.2 VIEW-ONLY STATUS
If a user attempts to enter Program Mode without providing a correct lockout code, the gauge briefly provides an
error message, and then enters a “view-only” status, denoted by the PRGM indicator flashing. In this mode, all
programmable registers except the lockout code register itself can be viewed, but not changed.
In this view-only status, the operator navigates through the programmable registers exactly the same as if
programming the programmable 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. The Up and Down Arrow keys do nothing within the register.
GAUGE IN MEASURE MODE
1. Press PRGM/ENTER to access P0 prompt
2. If lockout is active prompt will be L 00
• Enter Lockout Code
• Press the UP or DOWN ARROWS to change each digit
• Press PRGM/ENTER to enter each digit
If the correct code was entered, the gauge will perform the requested function. Otherwise, an error message is
displayed, and the gauge either returns to Measure Mode, or enters a “view-only” status for the programmable
registers (if Program Mode was requested).
