  • Page 12: Section 1.0: General Information

    Houston, Texas. This section of the manual provides general information about the DPC and presents its features and options. GENERAL INFORMATION The Ruska Model 7010 DPC uses force-balanced, fused-quartz Bourdon tube technology to provide the precise measurement of pressure. During normal operation, the DPC performs in either Measure mode or Control mode.

  • Page 13: Standard Equipment & Options

    Friendly Display: The DPC’s vacuum fluorescent display combines a bright, low-glare readout with a wide viewing angle. During normal operation, the measured pressure is easily visible from a distance of 10 feet (3 meters). Adjustable Pressure Display: The pressure display may be adjusted to show one decimal greater than or less than the default resolution.

    2.4.2 CONTROL MODE PNEUMATICS 2.4.2.1 PRESSURE SUPPLY PORT The Pressure Supply Port connects the user's regulated gas supply (see Section 3.5.1) to the Pneumatics Module, which is protected by a relief valve (RV03). 2.4.2.2 VACUUM SUPPLY (EXHAUST) PORT For many applications, a vacuum pump is not necessary. The Vacuum Supply Port includes a solenoid valve (SV06) that is open only when the DPC is in Control mode.

    SECTION 3.0 INSTALLATION INTRODUCTION This section of the manual discusses initial installation for the Model 7010 DPC. Installing the DPC involves connecting the supply and test pressure tubing, powering up the unit, and configuring the system through the front panel UNPACKING THE DPC Carefully unpack all components, checking for obvious signs of damage.

  • Page 33: Powering Up The Dpc

    1. Never operate the DPC with the cover removed. The power supply has internal voltages near 400 volts. 2. Never apply more than 120% of the DPC's full scale as a pressure supply. Pressure supply must be regulated and meet will criteria as stated in Appendix A of this manual. 3.

  • Page 34: Supply Vacuum

    The vacuum tubing from the pump tot he reference port should be a recommended 1/4-inch inner diameter or larger with a minimum length. If tubing with smaller than recommended inner diameters or long tubing lengths is used, longer pull down times may result. FIGURE 3-1A MODEL 7010 BACK PANEL INSTALLATION...

    4.2.7 ZEROING Ruska recommends that the DPC be zeroed once a day to maintain optimal performance. Zero drift is a separate specification from precision and stability. The zero drift specification is defined in Appendix A under General Specifications. Refer to section 6.4.4 in this manual for the zeroing procedure.

    6.3.2 REMOVING THE DPC'S COVER The DPC should be kept clean and completely assembled at all times. Operating the DPC without its cover affects the DPC's thermal gradients and therefore reduces precision. If it becomes necessary to remove the DPC's cover, follow the instructions below. CAUTION: The DPC should only be opened by qualified electrical/mechanical service technicians.

  • Page 67: Calibration

    DPC at any time by "editing the coefficients" (Section 6.4.3). 6.4.1 CALIBRATION INSTRUCTIONS To calibrate the DPC, the user connects a calibration standard such as the Ruska Instrument Model 2465 Gas Piston Gauge to the DPC's test port, then follows the three-step calibration procedure on the DPC's display.

  • Page 68: Storing The Coefficients

    1.2 Wait until the zero procedure finishes. This may take several minutes. When the DPC completes step 1, the calibration screen will appear. On High Pressure Models, pressure must be removed from the test port. If zeroing in Absolute mode, then the Test Port must be isolated. Step 2 2.1 To begin step 2, use the calibration standard to apply the 50% full scale +/- 5% of full scale pressure requested by the DPC.

  • Page 69: Vacuum (Negative Gauge) Calibrations

    Step 4 Calibration is complete. To exist the calibration procedure without storing the calibration coefficients in memory, press [CANCEL]. To store the calibration coefficients in memory, select OK [F6]. Step 5 Press [PREV.] to return to the Main Menu. Once the calibration procedure is complete, the user should verify several pressure readings against the pressure standard.

CAUTION: Never randomly adjust the calibration coefficients.

  • Page 72: Absolute Instruments

    For DPCs with ranges from 501 to 2500 psi, a test port isolation valve is not standard. For systems without this valve, it is important to vent the DPC and erify that there is not a pressure source supplying gas into the DPC test port before proceeding with the procedure outlined in Section 6.4.4.1.

  • Page 76: Shipping Instructions

    SHIPPING INSTRUCTIONS Ruska recommends using air freight for transportation. Surface transportation subjects the shipment to more frequent handling and much more intense shock. In most cases, if surface transportation is the mode of transport employed, handling damage is likely. Again, it is essential that the procedures mentioned in Sections 7.1 through 7.3 be strictly adhered to in order to prevent any shipping and handling damage to the instrument.
