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

flow 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 specified 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 flash “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 fitting. 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.
