Installation and Precautions
4 Read these instructions before using the gauge. Configuration may
be easier before installation. Contact the factory for assistance.
4 These products do not contain user-serviceable parts. Contact us
for repairs, service, or refurbishment.
4 Gauges must be operated within specified ambient temperature ranges.
4 Outdoor or wash down applications require a NEMA 4X gauge or
installation in a NEMA 4X housing.
4 Use a pressure or vacuum range appropriate for the application.
4 Use fittings appropriate for the pressure range of the gauge.
4 Due to the hardness of 316 stainless steel, it is recommended that
a thread sealant be used to ensure leak-free operation.
4 For contaminated media use an appropriate screen or filter to keep
debris out of gauge port.
4 Remove system pressures before removing or installing gauge.
4 Install or remove gauge using a wrench on the hex fitting only. Do
not attempt to turn gauge by forcing the housing.
4 Good design practice dictates that positive displacement liquid
pumps include protection devices to prevent sensor damage from
pressure spikes, acceleration head, and vacuum extremes.
 Avoid permanent sensor damage! Do not apply vacuum to nonvacuum gauges or hydraulic vacuum to any gauges.
 Avoid permanent sensor damage! NEVER insert objects into gauge
port or blow out with compressed air.
 Gauges are not for oxygen service. Accidental rupture of sensor
diaphragm may cause silicone oil inside sensor to react with oxygen.
WARNING: This product can expose you to chemicals including
lead, nickel and chromium, which are known to the State of
California to cause cancer or birth defects or other reproductive
harm. For more information go to www.P65Warnings.ca.gov
Types of Gauges
Gauge reference models read zero with the gauge port open.
Compound ranges read vacuum in inches of Mercury, pressure in
psig, and zero with the gauge port open.
1000 psi and higher sensors are a sealed reference type. They read
zero with the gauge port open are internally referenced to 14.7 psi.
They are functionally similar to gauge reference sensors.
Absolute reference gauges read zero at full vacuum and atmospheric
pressure with the gauge port open. Note atmospheric pressure varies continuously.
Power-Up and Operation
Press and hold the front button for approximately 1 second.
The display is tested, the default full-scale range is indicated, the
full-scale range in the selected units are indicated, the display is
tested again, then the actual pressure and units are displayed.

Power-Up With Zero (Gauge Reference Ranges Only)
Be sure the gauge port is exposed to normal atmospheric pressure
and no pressure is applied. The zeroing function is only activated at
each power-up and the stored zero correction is erased when the
gauge is shut off.
Press and hold the front button. The display is tested and then oooo
is displayed. The gauge is now zeroed. Release the button and the
full-scale range in the selected units are indicated, the display is
tested again, then the actual pressure and units are displayed.
Attempting to zero the gauge with pressure greater than approximately 3% of full-scale pressure or vacuum applied will result in
an error condition, and the display will alternately indicate Err 0 and
the actual measured pressure. The gauge must be powered down
to reset the error condition.
Normal Operation
Following the start-up initialization, the display indicates the pressure reading updated approximately 3 times per second. The auto
shutoff timer starts when the gauge is powered up or whenever the
button is pushed, unless the gauge shutoff time was set to zero for
on/off operation.
If excessive vacuum is applied to a pressure-only gauge, the display
will indicate -Err until the vacuum is released. Applying vacuum to
a gauge designed for pressure may damage the pressure sensor.
If excessive pressure is applied (112.5% over range), an out-of-range
indication of 1 – – – or 1.–.–.– will be displayed depending on model.
Operation—continued
Basic Configuration—continued
Display Backlighting (DPG3600, DPG5600 models only)
Display backlighting can be turned on by momentarily pressing the
front button whenever the gauge is on. The backlighting will turn on
for one minute and then automatically shut off. This also restarts
the auto shutoff timer. The display backlighting will not be apparent
under bright lighting conditions.
Minimum and Maximum Readings
Gauges are normally configured with minimum and maximum capture functions enabled. One or both can be disabled in the Advanced
Configuration mode.
Minimum and maximum readings are continuously stored and
updated whenever the gauge is on. The stored readings can be manually cleared if desired. The MAX and MIN memory is also cleared
whenever the gauge is off unless configured to save the readings.
Press and hold the button for about 1 second until MAX is displayed
alternating with the units. The maximum reading will be continuously updated. The gauge may be left in this mode.
After MAX is displayed, press and hold the button for about 1 second until MIN is displayed alternating with the units. The minimum
reading will be continuously updated. The gauge may be left in this
mode. If excessive vacuum is applied to a pressure-only gauge
while in this mode, the display will indicate –Err until the MAX/MIN
readings are cleared.
After MIN is displayed, press and hold the button again for about 1
second until * * * * is displayed. The MAX and MIN memory is not
erased and the gauge returns to normal operation with the display
indicating the current reading.
Press and continue to hold the button until the display indicates clr
MX/MN (about 3 seconds total) and then release the button. Both
maximum and minimum values are cleared and the gauge returns
to the normal mode and displays the current pressure.
Shut-Down
To shut off the gauge manually at any time, press and hold the button
until the display indicates OFF (about 5 seconds) and then release.
When an auto shutoff timer is used, the display indicates OFF five
seconds prior to auto shutoff. The button can be pressed to keep the
gauge on. The auto shutoff and backlight (if equipped) timers are
reset whenever the button is pressed and released.
If the gauge is set up without auto shutoff (on/off operation) it will
stay on until manually shut off or until the batteries are depleted.
Turn gauge off when not in use to conserve battery life.
Auto Shutoff Time Selection
Auto shutoff time selection is done via internal buttons to help prevent accidental or unauthorized changes. The selected shut off time
is stored in non-volatile memory and will be retained even with the
battery off or batteries removed.

readings may result.
1. Remove the 6 Phillips screws on the back of the unit.
2. Remove batteries by lifting up the positive end of the battery
(opposite the spring) taking care not to bend the battery holder
spring.
3. Discard old batteries properly, do not discard into fire, sources of
extreme heat, or in any hazardous manner.
4. Always replace both batteries at the same time with high quality
alkaline batteries. Install batteries with correct orientation. The
negative (flat) end of each battery should be inserted first facing
the battery holder spring.
5. Replace the back cover, including the rubber gasket.
Calibration Preparation
Gauges are calibrated at the factory using equipment traceable to
NIST. There is no need to calibrate the gauge before putting it into
service. Calibration intervals depend on your quality control program
requirements, although many customers calibrate annually.
Calibration should only be performed by qualified individuals using
appropriate calibration standards and procedures. The calibration
equipment should be at least four times more accurate than the
gauge being calibrated.
The calibration system must be able to generate and measure pressure/vacuum over the full range of the gauge.
A vacuum pump able to produce a vacuum of 100 microns (0.1
torr or 100 millitorr) or lower is required for vacuum and absolute
gauges. Warning: application of vacuum to non-vacuum models may
result in irreparable damage to the sensor.
Allow the gauge to acclimate to ambient temperature for 20 minutes.
Remove the rear cover to gain access to the UP and DOWN buttons
located near the lower right and left corners of the circuit board.
Install fresh batteries.
