Enabling the Lockout feature prevents unauthorized users from
making changes to 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 default as shipped from the
factory) disables the Lockout.
