Digital filter
Display:
FLtr
Range:
0
to
8
Default Value:
2
Displays and sets the digital filter value.
Digital filtering uses a weighted average method of
determining the display value and is used for reducing display value variation due to short term
interference. The digital filter range is selectable from
0
to
8
, where
0
= none and
8
= most
filtering. Use
^
or
v
at the
FLtr
function to alter the filter level if required. Note that the
higher the filter setting the longer the display may take to reach its final value when the input is
changed, similarly the relay operation and any output options will be slowed down when the filter
setting is increased. To set the digital filter value go to the
FLtr
function and use the
^
or
v
push buttons to set the required value then press
F
to accept this selection.
