Dwyer DPG-000 - Manual

The Series 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.
FEATURES
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.
INSTALLATION
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.

*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.
