Description These commands are used to specify the filter count. In general, the filter count is the number of
readings that are acquired and stored in the filter buffer for the averaging calculation. The larger
the filter count, the more filtering that is performed.
Programming example 10 OUTPUT 716; “:curr:ac:aver:coun 20; coun?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Sets the filter count to 20, and then queries the filter count.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the filter count (20).
