If removing a segment from a configured lineariser,
the segment to be deleted, which is shown on the
left hand side of the display, can be selected using
the
&
or
*
push button. When a segment is
deleted, the identification numbers of all segments
above the deleted segment are decreased by one.
Press
)
to return to the
dEL
prompt in the
lineariser sub-menu.
7.5 Input frequency:
PuL5E Fr
PuL5E Fr
is a sub-menu in the
FACtor
function for
entering the pulse input frequency at which each of
the lineariser segments starts, see Fig 13.
To enter the input pulse frequency at which one or
more lineariser segments start, select
FACtor
in the
configuration menu and press
(
which will reveal
one of four sub-functions. If
PuL5E Fr
is not
displayed repeatedly press the
&
or
*
button to
select
PuL5E Fr
followed by
(
to display the
current segment for which the start frequency will be
entered and the total number of segments that have
already been defined using the
Add
and
dEL
functions, see below.
The required segment, which is shown on the left
hand side of the display, can be selected using the
&
or
*
push button. When selected press
(
which will reveal the current input frequency with
one digit flashing. The value of the flashing digit
may be changed by pressing the
&
or
*
button.
When this digit is correct pressing
(
will transfer
control to the next digit. When the input frequency
for this lineariser segment is set as required, press
the
) button to return to the segment identification
display from which the next segment may be
selected using
&
or
*
push button.
When the input frequency for all of the segments
has been entered, return to the
FACtor
prompt in
the configuration menu by operating the
)
push
button.
7.6 Flowmeter K-factor
L-Factor
L-FACtor
is a sub-menu in the
FACtor
function for
entering the flowmeter K-factor for each of the
lineariser segments, see Fig 13.
The rate totaliser pulse input is divided by
L-FACtor
,
which is adjustable between
0.0001
and
99999
; for
flow applications it should be set to the K-factor of
the flowmeter. K-factor is the number of pulses that
the flowmeter produces per unit volume of flow e.g.
20 pulses per litre,
L-FACtor
therefore converts
the flowmeter output into engineering units ready
for further scaling to produce the required rate and
total flow displays.
To enter the flowmeter K-factor for one or more
segments, select
FACtor
in the configuration menu
and press
(
, which will reveal one of four sub-
functions. If
L-FACtor
is not displayed in the sub-
menu repeatedly press the
&
or
*
button to
select
L-FACtor
followed by
(
to display the
current segment for which
L-FACtor
will be
entered and the total number of segments that
have already been defined using the
Add
and
dEL
functions.
The required segment, which is shown on the left
hand side of the display, can be selected using the
&
or
*
push button, see below.
When selected, press
(
which will reveal the
current
L-FACtor
for the selected segment with
one digit flashing. The value of the flashing digit
may be changed by pressing the
&
or
*
button.
When this digit has been adjusted as required,
pressing
(
will transfer control to the next digit.
When all the digits have been adjusted pressing
(
will transfer control to the decimal point that
may be positioned between any of the digits, or
may be omitted by moving it to the right of the least
significant digit.
When
L-FACtor
for this lineariser segment is set
as required, press the
)
button to return to the
segment identification display from which the next
segment may be selected using
&
or
*
push
button. When
L-FACtor
for all of the segments
has been entered, return to the
FACtor
prompt in
the configuration menu by operating the
)
push
button twice.
7.7 Lineariser error messages
If an attempt is made to position a segment at an
input frequency which is not greater than the
frequency of the preceding segment, or at an input
frequency which is not less than the frequency of
the following segment, the error message
value.err
will be displayed.
