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.

Manually turns backlite on and off. (See

mode for options).

Press this key prior to gauge usage to rezero
any initial offset less than ±5% of the rated
gauge range. If indicated pressure is greater
than 5% of range, the rezero feature becomes
inoperable. This prevents accidental tare of a
pressurized gauge.

CALIBRAT.:
Gauge Calibration:

Both zero and span adjust­ments are available. This gauge has been con­figured with a default password of ШШШШШ. This
factory password does not allow access to cali­bration. To access the calibration mode, it is
necessary to configure a

user password. Once
the user password is configured, it will become
the default password that allows access to
gauge calibration

.

To access the factory default password:
Step 1:

Press the CONFIG key until the word

CALIBRAT appears.

Step 2: Press the ENTER key.
Step 3: The letters/asterisks… PW***** appear.

KEYPAD FUNCTIONS

Step 4:

Press the CONFIG key. An Ø appears in

the first position.

Step 5: Press the ENTER key once.
Step 6: Press the CONFIG key until Ø appears.

Ø will appear in the second position.

Step 7: Press ENTER.
Step 8: Use this format until all the asterisks are

replaced with Ø.

There now should be a total of five Ø’s on the
keyboard display. The zero in the fifth position
should be blinking.

Step 9: Press the ENTER key. You are now
prompted to SET PW (or set password).

Step 10: Press the ENTER key.
Step 11: Decide on a five number user pass-

word, then follow the procedure above inserting
a number in the flashing display until all five
numbers are inserted.

Step 12: A SAVE prompt will then appear. If the
selected user password is acceptable, press
ENTER. If the selected user password is not
acceptable press ZERO CLEAR to refigure the
user password.

After the password is configured, the default
factory password will be replaced with the user
password. Once configured, the factory pass­word is no longer accessible.

If an incorrect password is entered, the system
will display WRONG. Press the CONFIG key to
reenter the correct password.

Step 13: Press ENTER again to begin calibration.
Note: Calibration feature allows recalibration of

zero and span.
*Indicates default.

Step 14: Once the correct password is entered,
the user will be prompted to set the pressure to
zero followed by setting maximum gauge pres­sure (must be within 5% of the range).

If the user password is lost or stolen,
contact Omega customer service at (203)
359-1660 for a new factory password that
will allow the user to establish a new user
password.

Gauge Installation:
Pipe Mount – The

Omega

digital test gauge comes standard with a1⁄4NPT
connection. Good piping practices recommend using teflon tape or a pipe
sealant on the gauge threads. Utilize a

7

⁄16˝ 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.
Panel Mount – The lower connected

Omega

digital test gauge is available
with an optional flange for panel mounting. Please refer to illustration and
dimensions below.

!

Pipe to which gauge is attached must be properly grounded.

Battery Installation and Replacement:

The gauge comes standard with a quantity of three AAA alkaline batteries
(installed). Use either Duracell MN2400, MX2400 or Energizer E92BP,
X92RP AAA alkaline, non-rechargeable batteries.

Batteries have a life of approximately 1000 hours. Battery life is dependent
on gauge usage, backlite settings and power off settings. When the display
flashes LOW BAT, batteries should be replaced.

To replace the batteries:

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 three batteries from the holder and replace the
batteries. Use only AAA alkaline non-rechargeable batteries.
