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 bat-

teries need to be replaced.

Battery Replacement: Remove the three screws on backplate. Lift back-

plate off by hand. Replace batteries per polarity indicators. To reassem-

ble, 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.

WARNING: DO NOT pressurize DPG over maximum allowable pressure

limits. Extreme damage can occur if limits are exceeded (see Pressure

Limit under Specifications). An overflow “OFL” designator will flash to

acknowledge that the gage’s pressure range has been exceeded.
