Setup Menu – Operation Mode 4

Pressing the key opposite the word “Setup,” allows access to the setup operation mode. In the

setup mode, the user may select their preferred units of pressure that are displayed, restore

settings back to the default state, or calibrate the pressure sensors. The keys adjacent to the up

and down arrows on the lower right of the display are used to select one of the three options.

After toggling up or down, push the NEXT key to select the option.

Option 1

Units of Measure: If this option is selected, the key adjacent to “Next” is used to select pressure

units of inches of water/inches of mercury or mBar.

Helpful conversions are as follows:

1 mBar = .39 inches of water column

1 mbar = .0292 inches of mercury

1 inch of water = 2.52 mBar = .0737 inches of mercury

1 inch of mercury = 34.25 mBar

All pressures are measured with respect to atmosphere pressure.

Option 2

Restore Defaults: The restore defaults option restores all control settings to the initial

programmed settings which are listed in the back of these operating instructions.
