9.6.3 Setting the Digital Filter Parameters
Fine-tuning the digital filter parameters greatly improves indicator performance in heavy-vibration environments.
Use the following procedure to determine vibration effects on the scale and optimize the digital filtering
configuration.
1. In menu mode, set all three digital filters (DFLTR1, DFLTRL2, DFLTR3) to 1. Set DFTHRH to NONE.
Return indicator to normal mode.
2. Remove all weight from the scale, then watch the indicator display to determine the magnitude of vibration
effects on the scale. Record the weight below which all but a few readings fall. This value is used to
calculate the DFTHRH parameter value in Step 4.
For example, if a heavy-capacity scale produces vibration-related readings of up to 50 lb, with occasional
spikes to 75 lb, record 50 lb as the threshold weight value.
3. Place the indicator in menu mode and set the digital filters (DFLTRx) to eliminate the vibration effects on
the scale. (Leave DFTHRH set to NONE.) Reconfigure as necessary to find the lowest effective values for
the DFLTRx parameters.
4. With optimum values assigned to the DFLTRx parameters, calculate the DFTHRH parameter value by
converting the weight value recorded in Step 2 to display divisions:
threshold_weight_value / DSPDIV
In the example in Step 2, with a threshold weight value of 50 lb and a display division value of 5lb:
50 / 5lb = 10DD. DFTHRH should be set to 10DD for this example.
5. Finally, set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically
caused by lower vibration frequencies) will cause more consecutive out-of-band readings, so DFSENS
should be set higher to counter low frequency transients.
Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.
9.6.4 Audit Trail Support
Audit trail support provides tracking information for configuration and calibration events. To prevent potential
misuse, all configuration and calibration changes are counted as change events.
Use the Audit menu or Revolution to display audit trail information. This includes the legally relevant (LR) version
number (software version for the code that provides audit trail information), a calibration count and a configuration
count.
Audit trail information can be printed from Revolution or by sending the DUMPAUDIT serial command.
