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.
See label on back of gauge for range!
Use fittings appropriate for the pressure range of the gauge.
Do not apply vacuum to gauges not specified for vacuum operation. Per manent damage not covered by warranty will result to the sensor.
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.
NOTE:
DPG1000B, DPG1001B, DPG1000BBL, DPG1100B, DPG1100BBL
CAUTION:
Absolute Reference Gauges
These models have engineering units shown on the rear label such as PSIA, INHGA, INH2OA,
ZIN2A, BARA, MBARA, KPAA, TORR or TORRA,
MMHGA, KGCMA, ATMA. The “A” indicates absolute reference. These ranges display atmospheric pressure when the gauge port is open to the atmosphere. They display zero at high vacuum.
When the gauge port is open to the atmosphere, it is normal for the reading to constantly change in response to atmospheric pressure changes.
Do not adjust the calibration controls!
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.
If the gauge was ordered without auto shutoff (-
NS) 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.
Display backlighting on BBL models is on whenever the gauge is on. Backlighting may not be apparent under bright lighting conditions.
Operation – Rang es 2000 and up including 3000 psi, 5000 psi
These ranges have a 4-digit display with a lower alphanumer ic display. Press and hold the pushbutton for approximately 1 second. The fullscale range is indicated, display segments are tested, and the reading and units are displayed.
Power-Up With One-Touch Zero –
Ranges 2000 and up including 3000 psi,
5000 psi
1. Make absolutely certain no pressure is applied to the gauge. The gauge por t 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 o is displayed and then release the button. This indicates 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 E r r 0 and the actual measured pressure. The gauge must be powered down to reset the error condition.
Absolute reference gauges do not use the zero feature since they read atmospheric pressure under normal conditions.
Normal Operation – Ranges 2000 and up including 3000 psi, 5000 psi
Following the start-up initialization, the display indicates the pressure reading updated approximately 3 times per second and the units.
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 (-NS option).
If excessive vacuum is applied to a pressure-only gauge, the display will indicate – E r r 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 i – – – or i – . – . – . – will be displayed depending on model.
Display Backlighting (BBL models only)
– Ranges 2000 and up including 3000 psi, 5000 psi
Display backlighting can be tur ned 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. Backlighting may not be apparent under bright lighting conditions.
Shut-Down – Ranges 2000 and up including 3000 psi, 5000 psi
To shut off the gauge manually at any time, press and hold the pushbutton until the display indicates O F F and then release.
For gauges with auto shutoff, the display indicates O F F five seconds prior to auto shutoff. The pushbutton can be 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 (-
NS 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.
Battery Replacement – All Models
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.

Calibration Information
All gauges are factory calibrated on NIST traceable calibration equipment.
No calibration is required before placing the gauge into service.
Gauges can be returned to Omega Engineering for factory cer tified recalibration. 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.
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. Vacuum generation and atmospheric pressure measurement equipment for accurate calibration and thus these are more difficult to calibrate in the field.
Calibration Preparation – All Models
a. Calibration should only be performed by qualified individuals using appropriate calibration standards and procedures.
b. The calibration equipment should be at least four times more accurate than the gauge being calibrated.
c. Remove the screws on the back of the unit and remove cover.
d. It is good practice to install fresh batteries before calibrating batterypowered gauges.
e. Allow the gauge to equalize to normal room temperature before calibration.
DPG1000, DPG1001 - Pull out plastic plugs to access zero and span potentiometers
DPG1100 - Unscrew nylon screws to access zero and span potentiometers
Calibration of 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 known 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.
DOWN UP
Calibration of Ranges 2000 and up (with 4-digit 2-line display)
1.
Entering the Calibration Mode
a. Remove the back cover and note the locations of the two internal calibration pushbuttons marked UP and DOWN. These buttons are disabled unless the gauge is in calibration mode.
b. With the gauge off, press and hold the DOWN calibration button, and also press the front button to power up the gauge in calibration mode.
2.
Calibration Mode Functions
a. The display first indicates the gauge’s full-scale pressure range, tests all display segments, and then indicates CAL to indicate that the gauge is in the calibration mode. Release all pushbuttons.
b. The display will then indicate the current pressure reading, updating approximately 3 times per second. The gauge will remain in the calibration mode until powered down or reset manually. While in the calibration mode, the shutoff timer, One Touch Zero (gauge reference models only), Min/Max (for applicable models) are all disabled, and the calibration pushbuttons are active.
c. Each press of the UP or DOWN button makes a small correction, which may not always be indicated on the digital display. Press and hold the pushbutton for one second or longer to make larger continuous corrections. The display of the gauge being calibrated is adjusted to match the calibrator’s setting or readout.
d. If the batter y pack is unplugged or the power removed during calibration, calibration settings will not be saved.
3.
Gauge Reference Gauges (3 Points)
a. With the gauge port open to atmosphere, the character display will alternate between ZERO and CAL. Press the UP and DOWN buttons to obtain a display indication of zero.
b. Apply full-scale pressure. The character display will alternate between
+SPAN and CAL. Press the UP and DOWN buttons to obtain a display indication equal to full-scale pressure.
c. Apply 50% of full-scale pressure. The character display will alternate between +MID and CAL. Press the UP and DOWN buttons to obtain a display indication equal to 50% of full-scale pressure.
4.
Exit Calibration Mode and Verify Calibration
a. Exit the calibration mode and save the calibration data by pressing and holding the front button until the display indicates OFF.
b. Verify pressure indications at 0%, 25%, 50%, 75%, and 100% of full scale.
c. Replace the rear cover and screws, taking care not to pinch the power leads between the case and the rear cover.
