Zero Calibration
The Omniguard 4 does not require calibration between jobs. Internal
temperature compensation and other circuity provides unsurpassed
accuracy over a 30°- 130° Fahrenheit range.
Note: The clicking noise you hear the unit making is
it constantly compensating for zero offset drift. We
do recommend annual calibration verification.
To manually reset the zero point --
1. Disconnect the pressure tubing from INLET 1 and INLET 2.
2. Press MENU to view the Main Menu.
3. Highlight ZERO CALIBRATE using ▲/▼ and press SELECT to
choose zero calibration.
4. Press SAVE to calibrate and return to the Main Menu.
Pressing any other key will return you to the
Monitor Screen without resetting zero.
When completed, the screen will display DONE. After a few moments
the unit will automatically return to the Monitor Screen.
Note: Allow the unit 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.
