digital industrial gauge. This feature-packed gauge

offers a menu-driven display for easy customization.

User selectable features include 12 units of measure-

ment, password protected calibration and disable

functions, adjustable bar graph and update rate. A

five digit display for maximum resolution is standard.

Optional 4-20mA output, switching and line- power

add to the versatility of the gauge. With the range

printed on the keypad, Omega digital gauges meet

ASME B40.7 specification. See a complete listing of

product features and specifications on pages 18.

Turns the gauge on and off. When pressing the
ON/OFF key while in the off position, gauge start­up display first indicates the software version
followed by the model number and gauge pres­sure range. The gauge will then display indicated
pressure and be ready for use.

Press this key for one second prior to gauge
usage to rezero any initial zero shift. If zero shift
is greater than programmed zero allowance, the
gauge will display OFSET (blinking) for 1 sec­ond, then return to the measure mode. To clear
minimum and maximum values, press
ZERO/CLR button (when min/max values are
indicated). Gauge will auto advance once zeroed.

This key allows for customization of the gauge.
Pressing the MENU key allows cycling through
the main MENU items; UNITS, CONFIG, GRAPH,

Menu become the new default setting(s).
Revised settings are saved in the event of power
loss.

The



on the keypad allows for scrolling through the
MENU options to increase or decrease numeric
values as required. If in the menu mode, gauge
will automatically advance to measure mode
once selected MENU item has been set.

This key manually turns the backlite on or off.
five options are available. They include NEVER,
10 sec, 30, sec, 1 min, 5 min*. With the NEVER

option, the gauge BACKLITE will remain lit
whenever the gauge is in the ON mode or until
the BACKLITE button is pushed again. Options,
10 sec, 30 sec, 1 min, 5 min*. allow the BACK­LITE to automatically turn-off after a selected
period of time.

To use the BACKLITE option:
Step 1: Press the MENU key.

Step 3: press ENTER. The current setting (ENAB or dISAB)

will be displayed.
Step 4: Press the



Step 5: Press ENTER To finalize the setting.

GRAPH: This option allows the user to change the BAR

graph on the gauge display to correspond to any desired
pressure within the pressure limits of the gauge. This
option is useful when identifying a select portion of the
full-scale range of the gauge. The default setting for the
GRAPH is zero and full-scale pressure. For compound
gauges, the default setting for zero is set at full-scale vacu­um. Full-scale pressure is set at the positive pressure as
displayed on the gauge keypad.

For gauges supplied with the 4-20mA output option, the
default is 4mA equals 0% of the bar graph and 20 mA
equals 100% of the bar graph.

Changing the bar graph to a pressure other than 0 and
100% of range will also change the 4-20mA output to cor­respond with the new bar graph pressures for 0 and 100%.

To use GRAPH option:
Step 1: Press the MENU key.
Step 2: Press the



(up arrow key) or (down arrow key)

on the keypad until the word until the word GRAPH appears.
Step 3: Press ENTER . The gauge display will indicate the

set full scale pressure range setting on the top line. The
middle line indicates the bar graph at 100% of full-scale.
The bottom line of the display will indicate SETFS to set
the full-scale range as displayed by the bar graph and 4­20mA.

Step 4: Press the

Step 5: Press ENTER to finalize the selection.

DAMP or dampening: with five different options, this mode

allows for taking process pressure readings and averaging
them. This option is particularly useful to stabilize minor
process fluctuations. The options are NONE*, AVG 8, AVG
6, AVG 4, AVG 2.

Step 1: Press the MENU key until the word dAMP appears.
Step 2: Press Enter
Step 3: Press the



Step 4: Press the ENTER key to finalize your Damp option.

(This Menu item is only seen on units with the switch option)

SWSET: Allows for setting switch setpoints. The gauge is
offered with one or two SPDT switches. If (one) SPDT
switch is ordered the menu option is SW1. If (two) SPDT
switches are ordered, the MENU options are SW1 and SW2.

Step 1: Press the MENU key.
Step 2: Press the



(up arrow key) or (down arrow
key) on the keypad to select the switch to be set. (If two
switches are present.)

Step 3: Press ENTER. The top line of the gauge display will
indicate pressure at 60% of the full-scale gauge range* or
the most recent switch setpoint. The middle line of the dis­play will indicate a bar graph that displays the pressure
position within the pressure range. The bottom line will
display SETPT (blinking).

*Indicates default.

Note: Setpoints are limited to the full-scale pressure range
of the gauge.

Step 4: Press the



(up arrow key) or (down arrow key)

on the keypad to increase or decrease switch set-point
Step 5: Press the ENTER key to finalize switch setpoint. The

gauge will display SET. After two seconds, the top line will
indicate RETRP pressure. The bottom line will read SET.

Step 6: Repeat above to set RETRP (retrip value) If the
gauge is supplied with (one) setpoint, the screen will
advance to the measurement mode. If (two) switches are
supplied the display will advance to SW2.

Repeat the aforementioned if the gauge is supplied with
two switches.

Notes: The bar graph will increase or decrease as any
setpoint pressure is adjusted. The bar graph indicates
switch setpoint position within the full-scale pressure
range of the gauge.

The switch setpoint unit of pressure measurement corre­sponds with the current set unit of measure of the gauge.
If gauge unit of measurement is changed after switch(es)
is set, switch setpoint(s) will automatically be updated to
correspond with revised unit of measurement. Switch
deadband is the difference between the SETPT (setpoint)
and the RETRP (retrip) pressure.

GAUGE INSTALLATION:

The Omega

digital industrial gauge comes standard with either

1

⁄4or1⁄2NPT connection.
Good piping practices recommend using teflon tape or a pipe sealant on the gauge
threads. Utilize a

˝ (3˝ case),

5

⁄

8

˝ (4

1

⁄

2

˝ case) wrench on the wrench flat of the gauge to

tighten the gauge to the process.
NEVER TIGHTEN GAUGE THREADS BY HOLDING THE BODY OF THE GAUGE. DOING SO

MAY DAMAGE THE GAUGE AND MAKE THE GAUGE INOPERABLE.

!

Pipe to which gauge is attached
must be properly grounded.

Battery Installation and Replacement:

The Types DPG9030 and DPG9045 come standard with batteries installed. The 3˝ case
uses qty (2) AA alkaline batteries, the 4

1

⁄2˝ case uses qty (2) C alkaline batteries. Use
either Duracell MN2400, MX2400 or Energizer E92BP, X92RP AAA alkaline, non­rechargeable batteries.

Batteries have a life of approximately 1500 hours (3˝ case). 3600 hours (4

1

⁄

2

˝ case).
Battery life is dependent on gauge usage, backlite settings and power off settings.
When the lower bar of the battery icon of the gauge display flashes, the gauge has
approximately 7 hours of life remaining.

To replace the batteries (3˝ case):

1) Remove the single screw on the back of
the gauge case.

2) Hold the keypad in the palm of hand.

3) Carefully remove the two batteries from
the holder and replace batteries. Use only
AA alkaline non-rechargeable batteries.

To provide maximum battery life, replace
both batteries.

To replace the batteries (4

1

⁄

2

˝ case):

1) Remove the ring on the front of the
gauge case.

2) Looking at the gauge case, carefully
pull the front face out of the case.

3) Lay the gauge, face down on a flat sur­face.

4) Carefully remove the two batteries from
the holder and replace the batteries.
Use only C alkaline non-rechargeable
batteries. To provide maximum battery

life, replace both batteries.

Notes:

1) Do not mix ages or brands of batteries.

2) Do not replace batteries in hazardous
areas.
