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.
