Log Rates: The logging and printing of pressure readings begins once
the pressure reaches the normal operating window (status indicates
NORMAL). There are two rates at which logging occurs
Normal Operation: (default is 15 min.)
• Setting choices are 5, 15, 30 minutes of Off.
• When set to Off, Omniguard will only log & print pressure
readings during an Alarm Condition.
Alarm Condition: (default is 15 sec.)
• Setting choices are 15 sec, 30 sec, 1 min or 2 min.

Screen Settings (including Touchscreen Calibration)
To adjust the Screen Brightness --
1. From the Home screen, touch to go to the Main menu.
2. From the Main menu, touch Screen Settings.
3. Touch the current Screen Brightness setting to adjust to the
desired brightness level.
To Calibrate the Touchscreen --
1. From the Home screen, touch to go to the Main menu.
2. From the Main menu, touch Screen Settings.
3. Touch Calibrate Touchscreen to begin the calibration process.
4. A white box with an X in the middle of it will appear. With the tip
of the finger or by pressing gently with a stylus, touch the X. The
get closer to touching the center of X, the better.
5. Repeat this process 3 more times, until the Omniguard shows the
calibration is completed.
Zero Calibration
The Omniguard does not require calibration between jobs. Internal
temperature compensation and other circuitry provides unsurpassed
accuracy over a 30°- 130° Fahrenheit range.
Note: A soft clicking sound is made by the
Omniguard as it is constantly compensating for
zero offset drift due to changes in barometric
(atmospheric) pressure. Annual NIST calibration
verification is recommended.
To manually reset the zero point --
1. Disconnect the pressure tubing from both inlet nozzles.
1. From the Home screen, touch
to go to the Main menu.
2. From the Main menu, touch Zero Calibration.
4. Touch Calibrate Now. (If Passcode Protection is On, Omniguard
will prompt for the Passcode.)
5. When the calibration is complete the screen will read Calibrate
Zero Done.
6. Touch
to return to the Main menu.
Note: Allow the Omniguard to warm up for 15
minutes prior to zero calibrating. This permits the
pressure sensor to stabilize its readings. Zero
calibration can only be done when the pressure
tubing is not attached to the unit.
Passcode Protection
The passcode protection feature allows the site manager to assign
a passcode that prevents unauthorized changes to the Omniguard’s
settings. Once enabled, the passcode must be entered to change any
setting. Settings may be viewed without the passcode.
Passcode Protection : (default is Off)
Passcode : (default is 0 0 0 0)
• A passcode is always required to Erase Job Logs and
Restore Factory Defaults.
• Master passcode is 5 5 5 5
To set and activate Passcode Protection --
1. From the Home screen, touch to go to the Main menu.
2. From the Main menu, touch Passcode Protection.
3. Touch Off to enable or On to disable Passcode Protection.
Note : Disabling Passcode Protection requires
knowing and entering the Passcode.
