    3. Initial Setup and Basic Pressure Generation 1. The JOFRA HPC600 is supplied with a special low volume calibration hose kit to facilitate faster pumping to pressure and quick pressure stabilization. the kit also comes with the required “quick-fit” hose connectors and a BSP adapter for non-NPT applications.

  • Page 22: Electric Pump Considerations

    3.1 Electric Pump Considerations The JOFRA HPC600 a small, lightweight, battery powered pneumatic pump that allows the user up to 10 bar (150 psi) quickly and with good control. Because the pump has an upper pressure generation limit of 11 bar (160psi) there may be atmospheric conditions where it cannot achieve the full scale pressure of 10 bar.

  • Page 23: Measuring Pressure

    See section 2.3. 4.1 Media Compatibility The JOFRA HPC600 features a unique user accessible valve cleaning port to facilitate servicing the pump. Section 15.3 shows how to clean these valves. Even though servicing the pump is easy, care should be taken to only expose the calibrator to clean, dry gases.

    Figure 5 5. Measuring and Generating Current (4 to 20 mA) 1. To measure current use the input terminals in the front of the calibrator. Select the mA function on the lower display. Current is measured in mA and percentage of range. The range on the calibrator is set to 0% at 4 mA and 100% at 20 mA.

  • Page 27: Performing A Pressure Switch Test

    Note: The display will indicate "OL" when the measured temperature is outside the nominal measurement range of the RTD function (below -40°C or above 155°C). If a custom probe is being used, or adjustment of a standard probe is wanted, entering of CvD parameters, R0 and coefficients is handled through the serial interface, see remote programming manual.
  • Page 28 To perform a switch test, follow these steps: 1. Change the setup to Setup 4 (default switch test). Setup 4: The upper display is set to [P1] ST, all other displays are off. Important NOTE: The pressure Switch Test can be performed with the following functions[P1] ST, or EXT ST.
  • Page 29 8. Press the “NEXT” option to view when the switch closed, and the dead band. 9. Press the “NEW TEST” option to clear the data and perform another test. 10. Press the “DONE” option to end the test and return to the standard pressure setting.

  • Page 30: Calibrating Transmitters

    9. Calibrating Transmitters 9.1 Using the mA Input Function The mA input function allows the user to read back the 4-20 mA output from the device being calibrated. This can be done in one of two ways. 1) Passively – Where the device under test directly generates 4-20 mA and can be read by the calibrator.

  • Page 31: Percent Error Function

    Figure 10. 9.3 Percent Error Function The calibrator features a unique function which can calculate pressure vs. milliamp error as a percentage of the 4 to 20 mA loop span. The percent error mode uses all 3 screens and has a unique menu structure. It simultaneously displays pressure, mA and percent error.
  • Page 32 Example: Suppose a pressure transmitter under test is 30 psi (2 Bar) full scale and outputs a corresponding 4 to 20 mA signal. The user can program in a 0 to 30 psi pressure span into the calibrator and the calibrator will calculate and display the deviation or % Error from the expected 4 to 20 mA output.
  • Page 33 6. Use the arrow keys to set the 100% point of the desired pressure range, select DONE SET when finished. 7. Again, use the arrows to set 0% point and select DONE SET when finished and the %ERROR mode will be ready to use. Note: The 0% and 100% point will be saved in non-volatile memory until they are changed again by the user for the internal sensors, and external pressure modules.

  • Page 34: Minimum And Maximum Storage Capability

    10. Minimum and Maximum Storage Capability The HPC600 has a min/max feature for capturing the minimum and maximum values of any displayed parameter. The min/max function can be accessed by stepping through the menu options until “min/max” is shown on the display above the F1 key. At this time, pressing the F1 key will toggle the display through the min/max values that are stored in the min/max registers.

Setup 5: The upper display is set to [P1], the middle display is set to [EXT] and the lower display is set to RTD.

  • Page 38: Custody Transfer / Flow Calibration

    13. Custody Transfer / Flow Calibration The Model HPC600 is ideal for flow computer calibration. Every manufacturer of flow computers has a different calibration procedure, but most call for calibration of three parameters: static pressure, differential pressure and temperature. To facilitate these measurements recall setup #5 on the HPC600.
