    CPC3050 Turning On You can confirm that your CPC3050 is operational right now. Apply power to the power connector on the rear of the instrument with the included power cord, remove any plastic plugs from the rear panel pres- sure ports, and press the power switch to ON. The system will go through an initialization process, which takes about 30 seconds, and then a display will appear similar to the screen shown below.

  • Page 14: Front Panel

    CPC3050 Front Panel The CPC3050 front panel includes a 7” color LCD with touch screen. Operator input is accomplished by pressing the words or symbols and the App icons presented on the display. There is a single discrete on/ off button and a USB port on the right hand side. The front panel also shows the model number designa- tion and brand logos.

    CPC3050 (see Section 5.2 Dimensions and Section 8, Options). The special transducers used in the CPC3050 are relatively insensitive to tilt and vibration. However to further assure stability and accuracy, avoid mounting the instrument on surfaces subject to excessive mo- tor or machinery vibration.
  • Page 24 Allow at least 15 minutes of warm up before performing critical pressure measurements. Do not position the equipment so that it is difficult to remove the power cord. The instrument is not intended for connection of long-distance lines, i.e. lines within a building that are longer than 30 m, or that leave the building (including lines of outdoor installations).

  • Page 103 Warning Contamination Prevention Accessories The contamination prevention accessories allow the user to operate the CPC3050 on contamination prone devices. These accessories prevent contaminants like oil or dirt from entering into the instrument. These filters, when connected to the Measure/Control Port at the rear of the instrument, prevent any liquids to enter the controller when the direction of pressure flow is from device under test (DUT) to the controller or when the device under test is vented.
  • Page 104 • Repeat steps 3 to 7 until no more liquid is observed coming out of the system. • With the block and the bleed valves securely closed, vent the controller. Figure 8.7.2 – Contamination prevention accessories Operating Instructions - CPC3050...
  • Page 105 CPC3050 Pressure Booster To control pressure, the CPC3050 requires a pressure supply of 10% above the full scale of the instru- ment. The Model 75 Pressure Booster System provides the ability to boost bottle pressure up to the supply pressure requirements of all possible CPC3050 range configurations while maximizing gas bottle/ cylinder usage.

  • Page 107 High-Speed Pressure Controller CPC3050 Transducer Removal We suggest to send the CPC3050 to a Service Center to exchange any CPR3050 transducers. If removal is required outside of a Service Center, follow the following instructions for transducer removal or replacement: • VENT THE SYSTEM by placing the controller in vent mode. Then turn off the power.
  • Page 108 9.3.1 Barometric Reference Removal To remove the optional Barometric reference, first turn off the CPC3050 and loosen the Phillips head screws to remove top cover of the chassis The barometric reference can be removed by removing the attached ribbon cable, loosening the thumb screw, and lifting the barometric reference out of the chassis.
  • Page 109 The setpoint value is not reached. Check whether the value of the supply pressure is the value required, and leak test the plumbing. If you need help or assistance, contact Mensor at Phone: 1-512-396-4200 or 1-800-984-4200 (USA only) Fax: 512-396-1820 Website: www.mensor.com...
  • Page 110 10.2 Environment For maximum accuracy, allow the CPC3050 to warm up a minimum of 15 minutes in ambient temperature within the compensated range prior to a calibration. In addition, the instrument should be at rest on a stable platform that is free of excessive vibration and shock.
  • Page 111 A diaphragm type vacuum gauge is recom- mended over the gauge tube type of vacuum sensor for calibrating sub-atmospheric pressures. A vacu- um pump with the capacity to generate 600 mTorr absolute is recommended. Figure 10.5 – Calibration Setup Operating Instructions - CPC3050...
  • Page 112 For gauge pressure simply expose the reference and the Measure/Control port of the CPC3050 to atmospheric pressure and then press the “New Value” button and enter zero (0) using the keypad. For an absolute transducer apply a known reference pressure between 600 mTorr absolute and 20% of the active transducer’s span to the Measure/Control port of...
  • Page 113 Select a Transducer to calibrate by pressing the Channel button at the top of the screen. To calibrate the “Low Point”: 1. The Measure/Control port of the CPC3050 being calibrated should be supplied with a suitable, “low point” pressure (see section 5.4 Rear Panel for the port location).
  • Page 114 5. The “High Point” Calibration is done in a similar way as the “Low Point”. 6. Supply a pressure to the Measure/Control Port of the CPC3050 being calibrated, using a pressure standard. This pressure should be as close as possible to the full scale value of the selected trans- ducer or at least within 20% of the active transducer’s span.
