DPG 1000B & DPG 1000BBL DIGITAL PRESSURE GAUGE USER’S GUIDE
1.0 Installation and Precautions
Install or remove gauge using wrench on hex fitting only. Do not attempt to tighten by turning housing or any other
part of the gauge. Use fittings appropriate for the pressure range of the gauge. Do not apply vacuum to gauges
not designed for vacuum operation.
Due to the hardness of 316 stainless steel, it is recommended that a thread sealant be used to ensure leak-free
operation.
NEVER insert objects into the gauge port or blow out with compressed air. Permanent damage not covered by
warranty will result to the sensor.
2.0 Operation – Ranges up to 1999
Press the round button on the front of the gauge to activate the display. The gauge will stay on for a period of time
determined by the auto-shutoff time. The gauge can be shut off at any time by pressing the button again. Display
backlighting on DPG1000BBL models is on whenever the gauge is on. If the gauge was ordered witho ut au to
shutoff it will stay on until the button is pressed or until the batteries are depleted. Turn gauge off when not in use
to conserve battery.
3.0 Operation – 3000 psi, 5000 psi Ranges
Press and hold the pushbutton for approximately 1 second. The full-scale range is indicated, d isplay segments are
tested, and then the reading is displayed.
Power-Up with One-Touch Zero (Gauge reference models only)
1. Make absolutely certain no pressure is applied to the gauge. The gauge port should be exposed to normal
atmospheric pressure. Note that the zeroing function may only be activated at power-up and the stored
zero correction is erased when the gauge is shut off.
2. Press and hold the pushbutton.
3. The full-scale range is indicated and the display segments are tested.
4. Continue to press the pushbutton until
that the gauge has been zeroed.
5. The actual pressure is displayed.
Attempting to zero the gauge with pressure greater than approximately 3% of full-scale applied will result in an error
condition, and the display will alternately indicate 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 approxi mately 3 times per
second. The auto shutoff timer starts when the gauge is powered up or whenever the button is pushed, unless the
gauge was ordered without an auto shutoff time (-ON option).
If excessive vacuum is applied to a pressure-only gauge, the display will indicate
leased. Applying vacuum to a gauge designed for pressure may damage the pressure sensor.

until the vacuum is re-

Display Backlighting (BBL models only)
Display backlighting can be turned on by momentarily pressing the 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.
Shut-Down
To shut off the gauge manually at any time, press and hold the pushbutton until the display indicates
5 seconds) and then release.
For gauges with auto shutoff, the display indicates
pressed to keep the gauge on. The auto shutoff and backlight (if equipped) timers are reset whenever the pushbutton is pressed and released.
If the gauge was ordered without auto shutoff (-ON option) 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.

4.0 Calibration
All Cooper gauges are factory calibrated on NIST traceable calibration equi pment. No calibration is required before
placing the gauge into service.
Ranges up to 1999: Remove the calibration potentiometer covers on the front of the unit to access the zero and
span controls.
Gauge reference units may be re-zeroed without affecting the span calibration. The gauge port must be open to
the ambient with no pressure or vacuum applied. Adjust the Zero control until the gauge reads zero with the minus
(-) sign occasionally flashing.
Span calibration should only be attempted if the user has access to a pressure reference of know accuracy. The
quality of the calibration is only as good as the accuracy of the calibration equipment and ideally should be at least
four times the gauge accuracy. Zero calibration must be done before span calibration. Record readings at three to
five points over the range of gauge and adjust span control to minimize error and meet specifications.
3000 psi, 5000 psi ranges: The calibration adjustments are internal on these models.
Absolute Reference: These models display atmospheric pressure if the gauge port is open to the ambient. It is
normal for the reading to constantly change in response to atmospheric pressure changes. Vacu um generation
and atmospheric pressure measurement equipment for accurate calibration and thus these are more difficult to
calibrate in the field.
Gauges can be returned to Cooper Instruments for factory certified recalibration, repai rs and refurbishment. NIST
traceability is available. Gauges can also be recalibrated by any metrology lab with pressure calibration equipment
at least four times more accurate than the gauge.
5.0 Battery Replacement
A low battery indication will be shown in the upper left-hand corner of the display when the battery voltage falls sufficiently. The battery should be replaced soon after the indicator comes on or unreliable readings may result.
Remove the 6 Phillips head screws on the back of the unit.
Carefully remove batteries from the holders by lifting up the positive end of the battery (opposite the spring). Take
care not to bend or distort the battery retention springs.
DO NOT discard the old battery into fire, any other sources of extreme heat, or in any other hazardous manner.
Please consult local authorities if there is any question about proper disposal.

Always replace both batteries at the same time with high quality alkaline batteries. Observe the polarity of the batteries when replacing them. The negative (flat) end of each battery should be inserted first and should face the
spring in the battery holder.
Replace the back cover, including the rubber sealing gasket.
