The Series DPGAB & DPGWB Digital Pressure Gages have a precise ±0.5% 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 DPGAB & DPGWB 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. “OFL” may also be displayed when the device subjected to electromagnetic

interference between 0.9 to 1 GHz.

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.
