The Series DPG-100 Digital Pressure Gage has a precise +/- 0.25% 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-100 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 features include backlight, peak and valley, auto zero and conversion of the pressure units.
Readings may be converted to various engineering units. See reverse page for available units.
DPG Quick Start Button Operation
For complete detailed instructions on the four button operation see the
Operation 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 next page for Model/Range Chart).
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 housing to tighten the gage to a mating fitting. Do not apply wrench to housing.
MAINTENANCE
A “LOW BAT” descriptor indication will appear on the display when batteries need to be replaced.
Battery Replacement: Remove the three screws on backplate. Lift backplate off by hand. Replace batteries per polarity indicators. To reassemble, ensure O-Ring seats into housing evenly and press until seated completely. Replace screws.
WARNING Substitution of components may impair intrinsic safety.
Batteries must be changed in a non-hazardous location only.
DO NOT mix batteries from different manufacturers. DO NOT mix old batteries with new batteries. Use 1.5 volt AAA alkaline batteries Duracell ® MN2400.
WARNING sparking.
Enclosure parts are constructed of plastic. When cleaning the exterior surfaces use a damp cloth to avoid electrostatic
WARNING Enclosure parts are constructed of aluminum. Enclosure must be protected from mechanical friction and impact with iron/steel to prevent ignition capable sparks.
