Dwyer Instruments DPG-000 Series Installation and operating instructions

The eries DPG-000 Digital Pressure Gage has a precise +/-
0.50% full scale accuracy. The 4 digit digital display will reduce
the potential for errors in readings by eliminating parallax error
commonly produced with analog gages.
The DPG-000 is packaged in a durable extruded aluminum case
designed to meet NEMA 4/4X. The unit is battery powered and
has an auto-shut off to conserve battery life. A four button key
pad allows easy access to features without the need to work
through complex menus or difficult key combinations. These fea-
tures include backlight, peak and valley, auto zero and conver-
sion of the pressure units. Readings may be converted to vari-
ous engineering units. See reverse page for available units.
FEATURE
For complete instructions on the four button operation see the
flow chart provided on back.
On/Backlight: Push to turn on; Press again for backlight.
Press and hold for 5 seconds to turn unit off.
Zero: Zeros the display - Push & hold for 2 seconds to zero the
display. If after pressing zero the display does not re-zero, the
unit is no longer meeting specified accuracy and should be sent
back to the factory for calibration. Do not use the zero button
when pressure is applied.
Units: Scroll (see reverse).
P/V: Peak recorded reading retrieved by initial push of
button; push again retrieves the valley or lowest value
recorded.
IN TALLATION
When installing gage always use 1˝ hex at the base of the hous-
ing to tighten the gage to a mating fitting. Do not apply wrench
to housing.
MAINTENANCE
Battery Removal: Remove the three screws on backplate. Lift
backplate off by hand. To reassemble, ensure O-Ring seats into
housing evenly and press until seated completely. Replace
screws.
Replace batteries per polarity indicators.
A “LOW BAT” descriptor indication will appear on the display
when batteries need to be replaced.
PECIFICATION
ervice: Liquids and combustible compatible gases.
Wetted Materials: Type 316L SS.
Housing Materials: Black Polycarbonate front & back cover,
anodized aluminum extruded housing with recessed grooves,
Polycarbonate Overlay, Buna-N O-Rings, 316L SS Sensor

Agency Approvals:
CE EMC Directive:
EN 61000-4-2
EN 61000-4-3 & ENV50204
EN 61000-6-2
EN 61000-6-4
EN 55011.
*Note: Gages with ceramic sensor are not CE approved.
WARNING: DO NOT pressurize DPG over maximum allowable
pressure limits. Extreme damage can occur if limits are exceed-
ed (see Pressure Limit under Specifications). An overflow “OFL”
designator will flash to acknowledge that the gages pressure
range has been exceeded.

Press to turn unit on.
Press again to turn backlight on (backlight: 2 minute auto shut-off).
Press again to turn backlight off.
Push and hold for 5 seconds to turn unit off.
Press and hold to zero display if a value is read when no pressure is applied.
If after pressing zero the display does not re-zero, the unit is no longer meeting specified accuracy and
should be sent back to the factory for calibration.
DO NOT use the zero button when pressure is applied.
Press to scroll through engineering units.

election of Units on Compound Ranges
Engineering units for vacuum readings may be set independently from engineering units for positive pres-
sure readings. When selecting engineering units for vacuum readings a vacuum (negative pressure) must
be applied to the instrument. The engineering units for positive pressure readings must be selected when
a positive pressure is applied to the instrument. Once selected, the DPG will recall and display the engi-
neering units chosen.
[Some units may not be present depending on range]
Press to read peak reading.
Press again to read valley reading.
Press and hold to reset peak and valley.
Press at any time to return to home display.
Auto hut-off Disengage
Press and hold , then press and hold . A decimal will blink indicating that auto shut-off is disengaged
and the unit is in “always-on” mode.
Repeat the process to return unit to auto shut-off mode. Unit will shut-off after 60 minutes.
