Series DPGA & DPGW Digital Pressure Gages
Specications - Installation and Operating Instructions
Bulletin A-34C
The Series DPGA & DPGW Digital Pressure Gages have a precise ±1.0% 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 DPGA & DPGW are packaged in an ABS plastic case. The unit is battery powered
and has an auto-shut off to conserve battery life. A two button key pad allows easy
access to features without the need to work through complex menus. These features
include, auto zero and conversion of the pressure units. Readings may be converted
to various engineering units. See reverse page for available units.
OPERATING INSTRUCTIONS
For complete instructions on the two button operation see the ow chart provided on
back.
On/Off: Press ON/OFF to toggle on and off. Device will automatically shut off after 20
minutes if not used.
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 specied accuracy and
should be sent back to the factory for calibration. Do not use the zero button when
pressure is applied.
Units: To change units, press both On/Off and Zero buttons simultaneously.
Overpressure Indicator: The LCD will ash “OFL”, if the pressure applied is over
105% F.S.
INSTALLATION
When installing gage always use 1˝ hex at the base of the housing to tighten the gage
to a mating tting. Do not apply wrench to housing.
MAINTENANCE
Battery Removal: Remove the screw on backplate. Lift backplate off by hand. To
reassemble replace backplate and screw.
Replace batteries per polarity indicators.
A “LOW BAT” descriptor indication will appear on the display when batteries need to
be replaced.
