  • Page 53: Pulse Output (Pulse)

    Output 1 and 2 Setup (OUT 1, OUT 2) The function of open collector output 1 and 2 is configured using the Off, Pulse, Alarm, and Timer menus detailed below. 5.3.14 Pulse Output (PUlse) Pulse outputs may be assigned to rate, total, grand total, retransmit, quadrature, or test. Rate Pulse Output (rate) A rate-based pulse output is a factor of the rate display and count (output K-factor).

  • Page 54: Alarm Output (Alrm)

    For example, if the input K-factor value is set to 10, and the count set to 10, one output pulse is generated for every 100 input pulses. Total & Grand Total Pulse Output (Total, Grtot) A total and grand total based pulse output is a factor of the associated total and count (output K-factor).
  • Page 55 Rate Alarm (rate) Program the rate set point to trigger the alarm. Rate alarm deadband is determined by the difference between set and reset points. Minimum deadband is one display count. If set and reset points are programmed the same, output will reset one count below set point. Total or Grand Total Alarm (Total, Grtot) Program total or grand total set point.

  • Page 56: Timer Output (Tmer)

    If the total/grand total is set for manual reset, this alarm will remain until the total/grand total is reset to 0. If automatic total/grand total reset is enabled, the output will generate an alarm for a period of time programmed in ADVANCE  T RESET  Auto T DELAY. After this time delay, the total/grand total will reset to 0 and the alarm will clear.

  • Page 57: Gate Function (Gate)

    5.3.18 Gate Function (GATE) The gate function is used for displaying slow pulse rates. Using the programmable gate, the meter is able to display pulse rates as slow as 1 pulse every 9,999 seconds (0.0001 Hz). The gate function can also be used to obtain a steady display reading with a fluctuating input signal.

  • Page 58: Undoing K-Factor, Scale, And Calibration (Undo?)

    NOTE Performing a scaling or calibration operation will override any k-factor programming. Similarly, completing the k-factor menu will override any scaling or calibration performed on the meter. Verify the method of programming required, use the password protection feature to secure the meter if necessary. There are three methods of programming the display to show the correct engineering units based on input pulses.
  • Page 59 The pulse input can be scaled to display the process variable in engineering units. A signal source is not needed to scale the meter; simply program the inputs and corresponding display values. A programmed scaled input will work with Automatic Unit. The units for the display values that must be entered are a combination of the programmed Rate Unit and the time unit (Time UNIT) entered in the Scale menu.

  • Page 60: Multi-Point Linearization (Nopts)

    5.4.2 Multi-Point Linearization (nopts) Up to 32 linearization points can be selected under the nopts function. The multipoint linearization can be used to linearize the display for non-linear inputs. 5.4.3 Number of Points (nopts) Enter number of linearization points. The default value is 2 points. For linear inputs requiring only 2 scale points, the number of points can be left at 2.

  • Page 61: Important Programming Note: Save (Save?)

    5.4.8 Important Programming Note: Save (save?) After entering the last display value, the scaling entries must be saved (SAUE?) before they will be put into effect. However, you may move past this selection using the Up-arrow key if you need to go back and correct an earlier entry.

  • Page 63: Important Programming Note: Save (Save?)

    The multi-point linearization feature (nopts) can be used to linearize the display for non-linear signals. For instructions on how to utilize this feature, see Multi-Point Linearization (nopts). For instructions on how to program numeric values see Setting Numeric Values. Press the Up-arrow button to scroll to the Calibration menu (CAL) and press Enter. The meter displays nopts.
