Display Summary of function
di5P-1
Upper display
Defines whether
rAtE
or
totAL
is
shown on the upper display. The
other variable will be shown on the
lower display, providing the lower
display is
on
in function
dI5P-2.
See section 6.9
di5P-2
Lower display
Turns the lower display, which
normally shows rate,
on
or
oFF
.
See section 6.10
dP
Decimal points
Defines the position of the decimal
point in both the rate and total
displays.
See section 6.11
FACtor
Flowmeter K-factor
The rate totaliser pulse input is
divided by
FACtor
, which is usually
set to the K-factor of the flowmeter,
thus converting the flowmeter output
into engineering units.
FACtor
may be
adjusted between
0 . 0001
and
99999
.
When the 16 segment lineariser
Lin
is selected in the Function sub-menu,
up to 16 values for
FACtor
may be
entered, each at a specified input
pulse frequency to compensate for
flowmeter non-linearity.
See section 6.12
5CALE.t
Total Scale Factor
5CALE-t
is a dividing factor that
converts the pulse output from
FACtor
into the required total display in
engineering units. e.g. if the output
from
FACtor
is one pulse per litre and
the total display is required in
thousands of gallons,
5CALE-t
should
be set to
4546 .1
which is the number
of litres in 1,000 imperial gallons.
5CALE-t
may be adjusted between.
0 . 0001
and
99999
.
The total flow display is independent
of the rate display.
See section 6.13
Display Summary of function
5CALE.r
Rate scale factor
5CALE . r
is a dividing factor that
converts the pulse output from
FACtor
into the required rate display
in engineering units. e.g. if the
output from
FACtor
is one pulse per
litre and the rate display is required
in gallons,
5CALE . r
should be set to
4 . 5461
which is the number of litres
in an imperial gallon.
5CALE . r
may be adjusted between
0 . 0001
and
99999
. The flow rate
display is independent of the total
flow display.
See section 6.14
t-bA5E
Timebase
Selectable multiplier allowing flow
rate to be displayed in units per
second, per minute or per hour.
Select:
tb-01
for flow / second
tb-60
for flow / minute
tb-3600
for flow / hour
See section 6.15
FiLtEr
Display filter
An adjustable digital filter to reduce
noise
on the rate display is
controlled by two parameters each
adjustable between
0
and
9
. The
first digit defines the amount of
filtering applied to the display, the
second deviation from the displayed
rate at which the filter will be
overridden and the rate display will
move rapidly to the new value.
See section 6.16
CLP-oFF
Clip-off
To prevent totalisation of very low
flow rates, clip-off enables the user
to select a flow rate display below
which totalisation is inhibited.
See section 6.17
