After selecting and configuring the special function, to enable it change to on the key status confirm in OK.
  • Page 51 SCALE Function It establishes a linear relationship between the MCS-XV input signal and what is shown at the display, according to the graphic below: Fig. 25 – SCALE Function (LINEAR) The image shown below presents de SCALE FUNCTION configuration menu.
  • Page 52 ³ The scaled indication at the display (#) may be changed to represent any engineering unit, such as: m/s, m % etc. The number of decimals, up to 4, shown at the display may be configured. The value for Input High must be necessarily higher than Input Low. On the other hand, Scale High and Scale Low may have any relationship between themselves: higher than, lower than or equal to, and they may have a signal before them.
  • Page 53 b) CONV Function By using the CONV function, the calibrator may convert any input signal into any output signal with galvanic isolation. It may, therefore, behave as a real transmitter.

To access the RAMP mode configuration menu, select the function after pressing the SPECIAL FUNCTIONS button.
  • Page 56 Fig. 31 – RAMP Function b) STEP Programing The STEP programming makes the calibrator output vary in pre-defined steps. It is useful in calibrations where some scale points are verified, for example: 0% - 25% - 50% - 75% - 100%. To generate setpoints, you must set the minimum and maximum range points (MIN and MAX), the output percentage change for each step (%) and generate the list ( button).
  • Page 57 SCALE Function The scaling of the output from MCS-XV allows it to simulate the operation of a transmitter. In this case, the display scaled indication (#) simulates the transmitter input (which can be changed by pressing the number indicated on the display and entering the desired value), and as output signal it can have any of the signals generated by the MCS-XV (e.g., 4 to 20 mA).

  • Page 64: Calibration Examples

    2.4.9. Calibration Examples a) Temperature Transmitter Calibration (RTD Input and 4-20 mA Output) Through the menus, you can configure the MCS- for mA input and output in RTD. The TPS (Transmitter Power Supply) is a source of 24 Vdc that provides power to the transmitter. In the example, the connection of the RTD is made using three wires and being simulated by the MCS- With this form of connection, there is no measurement error due to the resistance of the wires since these have the same length and gauge.
  • Page 65 Setup the MCS-XV as volts output and TC input and select the TC type. For the cold junction compensation, you can use compensating wires TC to connect the transmitter to the MCS-XV and choose the option of Internal cold junction compensation, or you can measure the temperature of the terminal of the transmitter and enter this value in the Manual option in the MCS-XV, thus eliminating the use of compensating wires.
  • Page 66 c) Pressure Transmitter Calibration Use TPS MCS- source to power the two-wire transmitter 24 Vdc and connect the current as illustrated below. Select mA (current) in the Input menu of the CH-1 and Pressure Input on CH-2 menu. To enable Channel 2 as input, press the icon and enable the CH-2 option.
  • Page 67 Current input readings can be scaled to pressure through the SCALE option. In this way the error between the input and output of the pressure transmitter is easily calculated. d) Pressure Switch Verification Pressure switches are devices that receive a pressure signal and have relay alarm. The relay is activated whenever the pressure passes above or below a certain setpoint alarm.
  • Page 68 Channel 2 must be enabled and selected PRESSURE. You must select the corresponding sensor. On Channel 1, select SWITCH input and enter PRESSURE SWITCH TEST. The MCS-XV shows the pressure measurement and the contact status (OPEN or CLOSED). Press RUN to start the test after filling in all required fields.

    5. PRESSURE SENSOR INSTALLATION AND ADJUSTMENT The MCS-XV calibrator allows the installation of new pressure sensors, as well as the adjustment of the capsules already installed. To perform the operations described in this section, please observe the recommendations and warnings.

  • Page 135: Installation

    5.1. Installation To install a new sensor on the MCS-XV, turn off the calibrator and remove the screws corresponding to the side where the sensor will be installed (C1 and C4 - right side / C2 and C3 - left side).
  • Page 136 Inside the calibrator, there is a connector available for each uninstalled capsule. Check its location and connect the capsule to the calibrator. If necessary, disconnect the fuse holder from the mA input for easy access when installing on the right side of the calibrator (slots for C1 and C2 available). ATTENTION: Pay attention to the polarity between the sensor and the calibrator connectors.

    When the SAVE button is pressed, a confirmation pop-up will be displayed. Press YES to continue and NO to cancel the operation. 5.2.2. mV Adjustment To perform the mV adjustment of a pressure sensor, use a connection jig as indicated in the picture below. Connect the jig to the sensor connector observing polarity.
  • Page 141 IMPORTANT: The standard electrical signal generator to be used in this adjustment process must have an accuracy of three or four times the accuracy described in the technical specifications of this calibrator. ATTENTION: Do not insert any voltage signal to the pressure sensor before accessing the adjustment menu.

  • Page 142: Pressure Adjustment

    5.2.3. Pressure Adjustment ATTENTION: For absolute, gauge, and vacuum pressure sensors, make the adjustment at a minimum of 6 (six) POINTS across the range. For low pressure and/or differential sensors, make the adjustment at least 11 (eleven) POINTS. IMPORTANT: We recommend the application of pressure close or equivalent to the full scale of the adsensorsbeing adjusted for at least 5 (five) minutes before performing the procedure.
