9.2.8 FIL.CNF (Filter Configuration)

Filter configuration is used to select:
• Adaptive Bandwidth Control (ABC) filtering or moving average filter [FIL.1]
• whether the value displayed on the meter is filtered or unfiltered [FIL.2]
• whether the value sent to the optional analog output is filtered or unfiltered
[FIL.3]
"FIL.1=0" for Adaptive Bandwidth Control (ABC filtering, which averages over
a larger number of samples when the input is not moving, but drops down to
no averaging for systematic input changes). "FIL.1=1" is for averaging over
a fixed number of samples. The number of samples to be used is selected
in "FIL TI".
"FIL.3=0" removes the selected filtering from the analog output (if that option
is installed in your meter). "FIL.3=1" puts the selected filtering on that
output. Usually you choose "FIL.3=0", relying on the signal conditioning
available at the device receiving the analog output data.

"FIL.CNF":
The 'MIN' button allows you to sequence through FIL.1, FIL.2, and FIL.3.
The 'MAX' button allows you to select the "0", "1", "2", or "3" state for each
"FIL" condition.
The 'MENU' button stores the selected values for all "FIL.CNF" condition(s)
changed and advances the meter to "FIL TI". Do not press the 'MENU'
button after each change within the submenu or the meter will advance to
the next menu item.
Adaptive Bandwidth Control takes the average of the samples except when
the input is rapidly changing. Patent applied for.
Every underlined "0", "1", "2", or "3" is the factory preset value.
