brgt
(display brightness)
Displays and sets the digital display brightness. The display brightness is selectable from
1
to
15,
where
1
= lowest intensity and
15
= highest intensity. This function is useful for improving the display
readability in dark areas or to reduce the power consumption of the instrument.
duLL
(remote input controlled display brightness)
This function will not be seen unless the
R.INP
function is set to
duLL
. Displays and sets the level
for remote input brightness switching, see
R.INP
function. When the remote input function is set to
duLL
the remote input can be used to switch between the display brightness level set by the
brgt
function and the
display brightness set by the
duLL
function. The display brightness is selectable from
0
to
15
, where
0
=
lowest intensity and
15
= highest intensity. This function is useful in reducing glare when the display needs to
be viewed in both light and dark ambient light levels.
The functions which follow are accessible via
CAL
mode only.
rEC_
(recorder/analog retransmission output low value)
Seen only when analog retransmission option fitted. Displays and sets the analog retransmission
(4-20mA, 0-1V or 0-10V, link selectable) output low value (4mA or 0V) in displayed engineering units. e.g. if it
is required to retransmit 4mA when the display indicates
0
then select
0
in this function via the
^
or
v
button. This function will not be seen if the
REC ctrI
function is set to
on
.
rEC~
(recorder/analog retransmission output high value)
Seen only when analog retransmission option fitted. Displays and sets the analog retransmission
(4-20mA, 0-1V or 0-10V, link selectable) output high value (20mA, 1V or 10V) in displayed engineering units.
e.g. if it is required to retransmit 20mA when the display indicates
500
then select
500
in this function via the
^
or
v
button. This function will not be seen if the
REC ctrI
function is set to
on
.
drnd
(display rounding)
Displays and sets the display rounding value. This value may be set to 0 - 5000 displayed units.
Display rounding is useful for reducing the instrument resolution without loss of accuracy, in applications
where it is undesirable to display to a fine tolerance. For example if
drnd
is set to
10
the display indication
will change in multiples of 10 only i.e. it will be able to display
0,10, 20, 30
etc. but not
2, 4,15
etc.
dCPt
(decimal point selection)
Displays and sets the decimal point. By pressing the
^
or
v
pushbuttons the decimal point position
may be set. The display will indicate as follows:
0
(no decimal point),
0.1
(1 decimal place),
0.02
(2 decimal
places) or
0.003
(3 decimal places).
FItr
(digital filter)
Displays and sets the digital filter value. Digital filtering is used for reducing susceptibility to short
term interference. The digital filter range is selectable from
0
to
8
, where
0
= none and
8
= most filtering. A
typical value for the digital filter would be 3. Use
^
or
v
to alter if required. Note that at higher filter values the
display update time will be increased.
REC ctrI
(Analog output mode)
Seen only when analog output option is fitted. Refer to the "Analog PI Control Output" chapter for an
explanation of the analog PI control functions available when the optional analog output 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.
