DISPLAY
The gauge has a two-line display with backlight option.
1
The top line is a 4 ⁄ -digit seven segment, numeric display
2
with a minus sign, and the bottom line has five alpha-
numeric characters. There is also a battery icon which will
display the battery power level with three segments:
• No segments filled: less than 10% battery life remaining
• One segment filled: 10% to 25% battery life remaining
• Two segments filled: 25% to 50% battery life remaining
• Three segments filled: 50% to 100% battery life remain-
ing
Notes:
(1.) When the batteries get too weak for the gauge to
operate reliably, the gauge will shut off. If the gauge is
turned on with batteries in this condition, the version
and range display will show momentarily, but the
gauge will again shut off. If the batteries are too weak
the gauge will not turn on.
(2.) Over/Under pressure conditions:
If pressure is applied that exceed the gauges full
scale pressure the display will read:
• top line: actual pressure to 105% (Not Blinking) a
series of dashes if over 105% of full scale.
• lower line: OVER (blinking)
If vacuum is applied that exceed the gauges
vacuum range the display will read:
• top line: actual pressure (Not Blinking)
• lower line: UNDER (blinking)
KEYPAD
There are five buttons on the keypad, which function as
follows:
On/Off:
This button manually turns the unit on or off without
regard to mode of operation.
When the unit is turned on, the gauge will display, in 1
second intervals, the following start up sequence:
• firmware version
- top line: numerical firmware rev number
- bottom line: VER
• pressure range (Note: compound ranges shall also
display the vac range.
• measure mode
- top line: Full Scale pressure range
- bottom line: units of measure to which the unit
was calibrated.

OMEGA DIGITAL PRESSURE GAUGES
- top line: numerical value of the pressure currently
being sensed by the gauge
- bottom line: current "selected / default" units of measure:
If the "On/Off" button is pressed and held for three
seconds, a menu will appear, which can be scrolled
through by pressing the "On/Off" button. The menu will
offer the following selections, which will be blinking to indi-
cate a selectable option:
• NEVER (default) – The gauge will stay on until the
"On/Off" button is pushed again.
• 5 MIN – The gauge will turn off five minutes after it is
turned on.
• 10 MIN – The gauge will turn off 10 minutes after it is
turned on.
• 20 MIN – The gauge will turn off 20 minutes after it is
turned on.
A selection is made by pressing the "On/Off" button for
three seconds while an option is blinking. Once a selec-
tion is made, or scrolled past "20 MIN," the gauge will
return to measure mode.
Zero/Clear:
With the gauge in the measure mode (measuring pres-
sure), this button will zero the display provided the reading
is below the lesser of 50 psi or ±5% of the pressure range
(e.g. between –5 and 5 psi on a 100 psi gauge).
Min/Max:
Pressing this button will display the maximum pressure
the gauge has sensed since being turned on, in the top
line of the display. The bottom line will read "MAX".
Pressing the button again will display the minimum pres-
sure the gauge has sensed since being turned on, and
show "MIN." Pressing a third time will revert the gauge
back to the measurement mode. The "MAX" or "MIN" val-
ues will be cleared by depressing the ZERO/CLEAR but-
ton with value displayed. Both values will be cleared when
the gauge is turned off (manually or automatically).
Light (optional):
This button toggles the display backlight on and off. How-
ever, if this button is held for three seconds a menu will
appear which can be scrolled through by pressing the
"Light" button. The menu will offer the following selections,
which will be blinking to indicate a selectable option:
• IMMED – The backlight will only be on while the "Light"
Shown with optional
protective boot.
