Lockout Select

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.
To set the Lockout Code follow these steps:
Keystroke
1. From the Measure
Mode press the PRGM
key. If the Lockout is set,
enter the correct
"password" when
prompted.
2. Press the up arrow key
twice.
3. Press the right arrow
key then the up arrow key
four times.
4. Press the right arrow
key, then press the up or
down arrow keys to
change the first digit.
Press the right arrow key
to proceed.
5. Press the right arrow
key when the desired code
is set. Lockout is
activated.
6. Press the left arrow key
twice.
