the configuration of the manometer. To enter the Program Mode, the user must
first enter the “password” (two-digit Lockout Code) within approximately 40
seconds when prompted. Failure to enter the correct two digit code within
approximately 40 seconds will return the unit to Measure Mode. Any two-digit
numeric code can be programmed. The factory Lockout Code of 00 (which is the
