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.

Analog output PI control
Display:
rec ctrI
Range:
on
or
OFF
Default Value:
OFF
Analog output mode - seen only when analog output option is fitted. This function allows selection
of
on
or
OFF
for PI control analog output. If set to
OFF
the analog output operates as a
retransmission output and uses the functions described in this chapter. If set to
on
the analog
output operates as a PI control output.
When this function is set to
on
the following associated functions will appear:
C.SEt
,
C.SPN
,
C_PG
,
C_Po
,
C.IG
,
CIL.H
,
CIL.L
and
REC SPAC
.
Refer to the separate “RM4 DIN Rail Meter Optional Output Addendum” booklet for description
of the analog PI control functions.
