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.

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.

PANEL MOUNT OPTION

Drill a 3-1/4˝ (82.55) diameter hole in a panel, locate three mounting
holes for a #6 screw 120° apart on a 3-58˝ (92.08) bolt circle.

MAINTENANCE

A “LOW BAT” descriptor indication will appear on the display when bat­teries need to be replaced.

plate 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.

Button Operation Action

Press and hold ON button
While gage is on press ON button
While backlight is on press ON button
While gage is on, press and hold ON button 5 seconds for unit to turn off.
With no pressure applied to the gage, press and hold ZERO button until
display flashes
If gage will not zero, then gage is no longer meeting specified accuracy
and should be sent back to the factory for recalibration

NOTE: Gage is not to be zeroed while pressure is applied

Press UNIT button to change units on gage (Not all units are available for
each range, please refer to model/range chart located below for available
units)
Press P/V button to read peak (highest pressure) measurement
Press P/V button again to read valley (lowest pressure) measurement
Press and hold P/V button to reset peak and valley
Press ON button to exit peak/valley
Auto shut-off will turn off an idle gage after 60 minutes. To disengage
auto shut-off, press and hold ON button, then press and hold P/V button.
A decimal will blink in the lower left hand corner of the display to indicate
the auto-shut off is turned off. To turn on auto shut-off, repeat above pro­cedure until decimal point stops blinking
