  • Page 43: Instrument Setup Via

    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 44 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 45 • 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 46: 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.

    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.
