CONDEC DPDG Digital Pressure Dial Gauge User Reference Manual CONDEC Part Number: 85616 0219246 Rev B 6/06
Introduction The CONDEC DPDG 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 CONDEC DPDG can be used as a calibration reference, or in any application where high accuracy pressure measurement is required. Many user configurable functions have been designed into the CONDEC DPDG including sampling rate, TARE, damping, auto shut off, and min-max.
Symbol Description Power OFF Power ON Earth ground Risk of Danger. Important information. Refer to manual. Battery Hazardous Voltage Conforms to ATEX requirements Certified by CSA as conforming to relevant Canadian and USA standards Conforms to relevant European Union directives.
Caution 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 DPDG to prevent damage to the pressure transducer inside. • Maximum torque allowed is 13,5 Nm = 10 ftlbs. NEVER exceed the torque allowed.
1. Engineering Units set. The unit is shipped configured to display PSI. By pressing the ▲ and ▼ (ZERO and MAX/MIN) keys you can scroll forward and backwards through the 18 standard engineering units plus a one custom unit/scale. When the desired unit is displayed, press ENTER or CONFIG. Pressure will now be displayed in the chosen engineering units. See the Specifications section of this manual for a list of available engineering units.
configuration. This is accomplished through a password protected “supervisory mode”. Press ENTER to access the supervisory mode, or CONFIG to return to normal operation. Supervisory Mode Press ENTER when “FUnC LOCK” is displayed, 0PWRD will be displayed on the gauge. The password to enter supervisory mode is 101, set using the ▲ and ▼ keys. Holding a key continuously will cause the display to advance more quickly for faster setting. The password is factory set and cannot be changed 1.
gauge. By setting a factor of 25, a 40 PSI pressure would display as 1000 (40 x 25). The engineering unit displayed on the CONDEC DPDG will be “Cust”. Normal Operation Turning the backlight on and off: Press the ENTER button. Zeroing the display: Press and hold the ZERO button. MAX/MIN: The CONDEC DPDG stores minimum and maximum pressure values in memory. Pressing the MAX/MIN button once will display the minimum pressure from memory.
WARNING Gauges ordered with the external power option will not come with batteries installed. Batteries MUST NOT be installed when operating on external power. External power option gauges are not approved for hazardous location use. Battery life Battery life is about 1500 hours (60 days) of continuous use with the backlight off. With intermittent use, batteries could last a year or more. There is a low battery icon in the upper left of the display. It will appear when battery level is low.
Over Pressure Protection: Ranges from 15 PSI to 500 PSI: 3X input pressure range 1,000, 3,000, and 5,000 PSI ranges: 2X input pressure range 10,000 PSI: 1.5X input pressure range Temperature Compensation 0°C to +50°C (32°F to +122°F) to rated accuracy Note: For temperatures from –10 °C to 0 °C and 50 °C to 55 °C add .005% F.S.
Approvals Class I, Div. 2, Groups A-D CE approved Appendix 1: CONDEC DPDG Calibration Procedure Overview Calibration adjustment of the CONDEC DPDG is performed electronically via internal software with the case closed. There are no mechanical adjustments; all calibration commands and adjustments are done via the keypad, using the display to guide the user through the calibration process.
the display should look as shown below. The pressure value displayed will be the full-scale value of the gauge. Procedure: Screens shown in this manual represent the displays shown with a 500 psi Gauge. The CONDEC DPDG will prompt the technician for the appropriate pressure at each calibration point. 500.00 PSI CAL MODE Use the Pressure Standard to output 500.00 psi (100%). After the output has stabilized, press the ENTER key to continue. As the unit takes readings, the screen will show ———-.
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 PSI CAL MODE Use the Pressure Standard to output 250.00 psi (50%). After the output has stabilized, press the ENTER key to continue. As the unit takes readings, the screen will show ———-.
0.00 PSI 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. PSI -12.00 CAL MODE Note: Only some ranges use vacuum calibration. If your gauge is not one, than this step will be automatically skipped and calibration will be complete. Use the Pressure Standard to output -12.00 psi.
Warranty CONDEC warrants that all CONDEC equipment and systems manufactured and sold by CONDEC and properly installed by an authorized CONDEC Distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed by the Distributor/OEM and accepted by CONDEC. All systems and components are warranted against defects in materials and workmanship for one year.
warranty. Should the seller be other than CONDEC, the buyer agrees to look only to the seller for warranty claims. No terms, conditions, understanding, or agreements purporting to modify the terms of this warranty shall have any legal effect unless made in writing and signed by a corporate officer of CONDEC and the Buyer. Calibration All new units are shipped with National Institute of Standards and Technology (N.I.S.T.) traceable certification at no additional charge.
