The DPG4000 combines the high accuracy of digital electronics with the convenience and ease of use of an analog test gauge. Accurate to ± 0.05% FS, the DPG4000 can be used as a calibration reference, or in any application where high accuracy pressure measurement is required. - Page 4 These areas are also referred to as hazardous locations, see NFPA 70 Article 500. Misuse Should the DPG4000 be exposed to overpressure or sudden physical shock (i.e. being dropped) it should be examined for any damage that may cause a safety concern. If in doubt please return the unit for evaluation to OMEGA Engineering, Inc.

To avoid possible damage to calibrator or to equipment under test: • If the message changes to "OL" the range limit is exceeded and the pressure source must immediately be removed from the DPG4000 to prevent damage to the pressure transducer inside. - Page 6 3. Display battery voltage. Actual voltage and a percent of life bargraph indicate battery condition 4. Display actual temperature. The DPG4000 is temperature compensated, this displays the temperature measured by the internal sensor. The value can be set to degrees F or degrees C using the arrow keys.

TUR of 4:1 or better. Connections: The DPG4000 uses a 1/4 NPT male connection in the pressure input port. Various adapters may or may not be needed to connect to the pressure standard. Always make sure the hose, tubing, and fittings etc have a rated working pressure at or above the pressure of the unit. - Page 12 Procedure: Screens shown in this manual represent the displays shown with a 500 psi Gauge. The DPG4000 will prompt the technician for the appropriate pressure at each calibration point. 500.00 CAL MODE Use the Pressure Standard to output 500.00 psi (100%). After the output has stabilized, press the ENTER key to continue.
- Page 13 Use the Pressure Standard to output 312.50 psi (62.5%). After the output has stabilized, press the ENTER key to continue. As the unit takes readings, the screen will show ———-. When the readings are complete the screen should look as shown below. 250.00 CAL MODE Use the Pressure Standard to output 250.00 psi (50%).
- Page 14 0.00 CAL MODE Use the Pressure Standard to output 0.00 psi. After the output has stabilized, press the ENTER key to continue. As the unit takes readings, the screen will show ———-. When the readings are complete the screen should look as shown below. -12.00 CAL MODE Note: Only some ranges use vacuum calibration.
