Installation and Precautions
4Read these instructions before using the gauge. Contact
the factory for assistance.
4These products do not contain user-serviceable parts.
Contact us for repairs, service, or refurbishment.
4Gauges must be operated within specified ambient tem-
perature ranges.
4Outdoor or wash down applications require a NEMA 4X
gauge or installation in a NEMA 4X housing.
4Use a pressure or vacuum range appropriate for the
application.
4Use fittings appropriate for the pressure range of the
gauge.
4Due to the hardness of 316 stainless steel, it is recom-
mended that a thread sealant be used to ensure leak-free
operation.
4For contaminated media use an appropriate screen or
filter to keep debris out of gauge port.
4Remove system pressures before removing or installing
gauge.
4Install or remove gauge using a wrench on the hex fitting
only. Do not attempt to turn gauge by forcing the housing.
4Good design practice dictates that positive displacement
liquid pumps include protection devices to prevent sensor
damage from pressure spikes, acceleration head, and
vacuum extremes.
p Avoid permanent sensor damage! Do not apply vacuum to
non-vacuum gauges or hydraulic vacuum to any gauges.
p Avoid permanent sensor damage! NEVER insert objects
into gauge port or blow out with compressed air.
Gauges are not for oxygen service. Accidental rupture of
sensor diaphragm may cause silicone oil inside sensor to
react with oxygen.
pNEVER connect the gauge wires directly to 115 VAC or
permanent damage will result.
Power
The AD series is powered by 8-24 VAC 50/60 Hz or 9-32
VDC.
The type and magnitude of the supply voltage have negli-
gible effects on the gauge calibration as long as it is within
the voltage ranges stated above. No polarity needs to be
observed when connecting a power supply. An inexpensive
unregulated low voltage AC or DC power supply can be used.
After the gauge is installed, route the wires away from heat
sources and moving equipment and connect the low-voltage
power source to the gauge wires.
Ensure that the gauge supply voltage does not fall below 8
VACRMS if AC power is used, or 9 VDC if DC power is used.
Operation with less than these values may cause erratic or
erroneous readings.
When operating multiple gauges from the same power
supply, refer to the mA rating in the specifications to ensure
adequate power.
Note that standard 24 VAC transformers often operate at
voltages well over the gauge’s 24 VAC limit.
Absolute Reference Gauges
These models have engineering units shown on the rear
label such as PSIA, INHGA, INH2OA, ZIN2A, BARA, MBARA,
KPAA, TORR or TORRA, MMHGA, KGCMA, ATMA. The
“A” indicates absolute reference. These ranges display
atmospheric pressure when the gauge port is open to the
atmosphere. They display zero at high vacuum.
When the gauge port is open to the atmosphere, it is normal
for the reading to constantly change in response to atmo-
spheric pressure changes. Do not adjust the calibration
controls!
Display Backlighting (ADBL models)
Red LED display backlighting on ADBL models is on whenev-
er the gauge is on. Backlighting may not be apparent under
bright lighting conditions.
Operation – Ranges up to 1999
Press the button on the front of the gauge to activate the
display.
The gauge can be shut off at any time by pressing the
button again.
If the gauge is in the power-on state and the power is dis-
connected, the gauge will turn on when power is reapplied.
The display indicates the pressure reading updated approxi-
mately 3 times per second. The gauge can be left on contin-
uously or turned off when not in use.
Display backlighting for BL models is on whenever the gauge
is on. The backlighting will not be apparent under bright
lighting conditions.
Operation – Ranges 2000 and up including
3000 psi, 5000 psi
Press and hold the front button for approximately 1 second if
the gauge does not turn on when power is applied.
When the supply voltage is applied, the gauge will go
through a power-up sequence. The full-scale range is indi-
cated, display segments are tested, and then the reading
and units are displayed.
The gauge may be zeroed at power-up by following the
procedure below. This feature corrects small deviations
from zero due to temperature changes. Absolute reference
gauges do not use the zero feature since they normally read
atmospheric pressure.
The gauge port must be exposed to normal atmospheric
pressure with no pressure applied. The zero function is only
used at power-up and the stored zero correction is erased
when the gauge is shut off.
Press and hold the front button.
The full-scale range is indicated and the display is tested.
Continue to press the button until oooois displayed and
then release the button.
The gauge is now zeroed and ready for use with the actual
pressure is displayed.
Attempting to zero the gauge with pressure greater than
approximately 3% of full-scale applied will result in an error
condition, and the display will alternately indicate Err0 and
the actual measured pressure. The gauge must be powered
down to reset the error condition.
Following the start-up initialization, the display indicates the
pressure reading updated approximately 3 times per second.
If excessive vacuum is applied to a pressure-only gauge,
the display will indicate –Err until the vacuum is released.
Applying vacuum to a gauge designed for pressure may
damage the pressure sensor. If excessive pressure is
applied (112.5% over range), an out-of-range indication of
I – – – or I –.–.–.– will be displayed depending on model.
Display backlighting for BL models is on whenever the gauge
is on. The backlighting will not be apparent under bright
lighting conditions.
To shut off the gauge at any time, press and hold the button
until the display indicates OFF (about 5 seconds) and then
release.

Calibration Information
All gauges are factory calibrated on NIST traceable calibra-
tion equipment. No calibration is required before placing the
gauge into service.
Gauges can be returned to Omega Engineering for factory
certified recalibration. NIST traceability is available. Gauges
can also be recalibrated by any metrology lab with pressure
calibration equipment at least four times more accurate
than the gauge.
Absolute reference models display atmospheric pressure if
the gauge port is open to the ambient. It is normal for the
reading to constantly change in response to atmospheric
pressure changes. Vacuum generation and atmospheric
pressure measurement equipment for accurate calibration
and thus these are more difficult to calibrate in the field.
Calibration Preparation – All Models
All gauges are factory calibrated using NIST traceable cali-
bration equipment. Calibration is not required before using
the gauge. Calibration intervals depend on your quality
standards, but annual re-calibration is customary.
Calibration equipment is not required to zero gauge refer-
ence ranges. Absolute reference ranges may be zeroed with
application of full vacuum.
Span calibration should only be performed using appropriate
calibration procedures with calibration standards that are
at least four times more accurate than the gauge being
calibrated.
The calibration system must be able to generate and mea-
sure pressure/vacuum over the full range of the gauge. A
vacuum pump able to produce a vacuum of 100 microns
(0.1 torr or 100 millitorr) or lower is required for vacuum
and absolute gauges.
Connect gauge to a 8-24 VAC 50/60 Hz or 9-32 VDC power
supply.
Allow the gauge to equalize to normal room temperature for
approximately 20 minutes before calibration.
Calibration of Ranges up to 1999
For DPG1000AD and DPG1100AD models remove the front
covers to access the zero and span calibration potentiom-
eters.
For DPG1100AD models unscrew the nylon cover screws to
access the zero and span calibration potentiometers.
Gauges may be re-zeroed without affecting the span cali-
bration. For gauge reference models the gauge port must
be open to the ambient. For absolute reference models full
vacuum must be applied.
Adjust the zero control until the gauge reads zero with the
minus (–) sign occasionally flashing.
Zero calibration must be done before span calibration.
Using the appropriate pressure standards, record readings at
three to five points over the range of gauge and adjust span
control to minimize error and meet specifications.
Calibration of Ranges 2000 and up including
3000 psi, 5000 psi
Entering Calibration Mode
Remove the rear cover to gain access to the UP and DOWN
buttons located near the lower right and left corners of the
circuit board.
With the gauge off, press and hold the DOWN calibration
button, and also press the front button.
The full-scale pressure range and display test is shown, and
then CAL is displayed to indicate that the calibration mode
is enabled.
Release all buttons. The gauge enters and remains in
the calibration mode until restarted manually or power is
removed. Features not related to calibration are disabled.
If the power is removed during calibration, settings will not
be saved.
The display will indicate the current pressure reading,
updating approximately 3 times per second.
Each press of the UP or DOWN button makes a small
correction, which may not always be indicated on the
display. Press and hold the button for one second or longer
to make larger corrections. The gauge’s display is adjusted
to match the calibrator’s reading.
