3.9.3 Response time (Digital filter)
The various filter parameters have the following effects on
the time needed to display, store, or output a filtered reading:
• Filter type: The time to the first reading is the same for
both types, but thereafter averaging mode yields a faster
reading than repeating mode. Also, advanced has a
faster response to changes in the input signal than
averaging.
• Number of reading conversions: Speed and accuracy
are trade-offs.
• Noise window: For the advanced type, a trade-off of
speed, accuracy, and response to input signal changes.
3.9.4 Auto filtering (Digital)
For those measurement functions with a filter, one of the
possible selections is automatic filtering. Depending on the
measurement function and type, the AUTO selection may
disable filtering. Auto filtering is summarized in Table 3-36.
3.9.5 Configuring the digital filter
Each measurement function except frequency has its own
configuration for a digital filter. A digital filter configuration
menu is shown in Table 3-37.
