Filters
The filter feature lets you set the filter response to stabilize noisy measurements. The Series 2600B
uses a digital filter, which is based on reading conversions. The displayed, stored, or transmitted
reading is calculated using one or more reading conversions (from 1 to 100).
Filter types
The Series 2600B has three filter types. These three filter types are broken down into two averaging
filters and one median filter.
The two averaging filters are repeating and moving (see figure below). For the repeating filter (which
is the power-on default), the stack (filter count) is filled, and the conversions are averaged to yield a
reading. The stack is then cleared, and the process starts over.
