  • Page 25: Ac Rms Volts & Amps Input

    13. AC TRUE RMS VOLTS & AMPS INPUT AC voltage or current measurement utilizes the True RMS signal conditioner board which uses precision circuitry to compute the root-mean-square of complex waveforms from 10 Hz to 10 kHz. Accurate measure- ments are obtained with spikes up to 3 times the maximum of each range.
  • Page 26 can be set for direct readout in (milli)volts or (milli)amperes. Decimal point selection does not affect the counts. For example, a 20V input may be displayed as 20.000V or 20000 mV. The 5A range, designed for use with a 5A current transformer (CT), is scaled to produce 5000 counts with a scale factor of 1 and an offset of 0.

    15. RTD & RESISTANCE INPUT The standard RTD and resistance signal conditioner board can be configured via jumpers for four RTD types (DIN 100 platinum, ANSI 100 platinum, 120 nickel, 10 copper) or five resistance ranges (from 20.000 to 200.00 k ). A fixed 2 M resistance range (R6 ordering option) is provided by a factory modified signal conditioner board with component changes.
  • Page 35 RTD & RESISTANCE CONNECTION With the appropriate jumper settings, RTD and resistance measurements allow 2, 3 or 4- wire RTD hookup to the J5 connector, as illustrated. The meter applies a fixed excita- tion current. In 4-wire hookup, lead resistance is not a factor, since different pairs of wires are used for excitation and sensing.

    19. EXCITATION OUTPUT & POWER SUPPLY Three isolated transducer excitation output levels are available from the power supply board. These are selectable via jumpers b, c, d, e, f in the upper right of the board, as illustrated. In addition, the board provides three jumper positions for special features. The same jumper locations apply to the universal power supply (85-264 Vac) and to the low voltage power supply (12-32 Vac or 10-48 Vdc).

  • Page 49: Instrument Setup Via Pc

    20. INSTRUMENT SETUP VIA PC Instrument Setup software is a PC program which is much easier to learn than front panel programming. It is of benefit whether or not the meter is connected to a PC. With the meter connected to a PC, it allows uploading, editing and downloading of setup data, execution of commands under computer control, listing, plotting and graphing of data, and computer prompted calibration.
  • Page 50 SETUP OF CONNECTED METER A setup file can be retrieved from the meter (DPM => Get Setup), be edited (View => Setup), be saved to disk (File => Save Setup), be retrieved from disk (File => Open Setup), and be downloaded into one or multiple meters (DPM => Put Setup). Downloading of setup files from a PC can be a major time saving when multiple meters have to be set up in the same way.
  • Page 51 • The Readings pull-down menu provides three formats to display DPM data on the PC monitor. Use the Pause and Continue buttons to control the timing of data collection, then press Print for a hardcopy using your PC printer. - List presents the latest readings in a 20-row by 10-column table. Press Pause at any time to freeze the display.

  • Page 52: Custom Curve Linearization

    21. CUSTOM CURVE LINEARIZATION Curve.exe is a DOS-based, executable PC program used to set up an Extended meter so that the readings have a user-defined, non-linear relationship with the input signal. The calculated linearizing parameters are downloaded into non-volatile memory of the meter. For example, it allows a meter to correct for transducer nonlinearity or to display volume of an irregularly shaped tank based on liquid level.
  • Page 53 4) Equation entry mode, where the coefficients of a polynomial Y = K1X^P1 + K2X^P2 + K3*X^P3 + are entered. Up to 20 terms are allowed. An offset can be built into X. You will be asked if your DPM has a revision of DPM4L or later. You will normally select 2 (yes), since revision DPM4L started to ship in August 2000.

  • Page 54: Meter Calibration

    22. METER CALIBRATION All analog input and analog output ranges of the meter have been digitally calibrated at the factory prior to shipment using calibration equipment certified to NIST standards. Calibration constants are stored digitally in non-volatile memory in EEPROM on the signal conditioner board and analog output board.

  • Page 59: Glossary Of Terms

    24. GLOSSARY OF TERMS Adaptive Filter Threshold A threshold which causes an adaptive moving average filter to be reset to the latest reading when the accumulated difference between individual readings and the filtered reading exceeds that threshold. Adaptive moving average filtering allows a meter to respond rapidly to actual changes in signal while filtering out normal noise.
  • Page 60 deviation band, and de-actuates when the reading falls outside. A limit (e.g., 50 counts) is set up around both sides of the setpoint to create a deviation band (e.g., 100 counts). Setting up a passband around a setpoint is often used for component testing.
  • Page 61 Hysteresis, Span Same relay operation as for split hysteresis, but specified differently. Here the setpoint is the upper control limit, and the lower control limit is the setpoint less the hysteresis band. The meter programming mode used for input Menu Mode and range selection, meter setup, and meter configuration.
  • Page 62 The value displayed by the meter. “Taking a reading” is the action of the meter Reading to make an analog-to-digital conversion. Readings are taken at 60/sec with 60 Hz power or 50/sec with 50 Hz power, and are displayed with an update rate of 3.5/sec with 60 Hz power or 3.0/sec with 50 Hz power.
  • Page 63 Scaling, Scale and Offset Method A scaling method where scale and offset are entered manually. Scaling, Reading Coordinates of 2 Points Method A scaling method, where the low and high input values are determined from actual signals. A known low signal is first applied to the meter. That signal is captured as the low input value, and the desired low reading is entered.

  • Page 64: Warranty

    In the event of a defect during the warranty period, the unit should be returned, freight prepaid (and all duties and taxes) by the Buyer, to the authorized Yokogawa distributor where the unit was purchased. The distributor, at its option, will repair or replace the defective unit. The unit will be returned to the buyer with freight charges prepaid by the distributor.
