6.12 Total scale factor:
5CALE
.
t
5CALE
.
T
is a dividing factor adjustable between
0.0001 and 99999 that enables the total to be
displayed in engineering units. e.g. if one input
pulse represents 1 centimetre of dispensed cable
and the total display is required in metres,
5CALE
.
t
should be set to 100.0 which is the number of
centimetres in a metre. If a display of the total
number of input pulses is required,
5CALE
.
t
should
be set to 1.0. The total display is independent of the
rate display.
To check or change the total scale factor select
5CALE
.
t
from the configuration menu and press
(
which will reveal the existing value 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 the total scale factor has been entered, press

5CALE

t
will disable the
following ouputs which must be re-enabled
after the adjustment is complete:
Optional Pulse output
Optional Alarm outputs.
Optional 4/20mA output.
6.13 Rate scale factor:
5CALE
.
r
5CALE
.
r
is a dividing factor adjustable between
0.0001 and 99999 that enables the rate display to be
in engineering units. e.g. if one input pulse
represents 2 pump strokes and the rate display is
required in pump strokes,
5CALE
.
r
should be set to
2.0. If just the rate of input pulses is required,
5CALE
.
r
should be set to 1.0. The rate display is
independent of the total display.
The units of the rate display are counts per unit of
time. The unit of time is the timebase of the
instrument which is determined by
t-bA5E
described in section 6.14.
To check or change the rate scale factor select
5CALE
.
r
from the configuration menu and press
(
which will reveal the existing value with one digit
flashing. The value of the flashing digit may be
adjusted 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 the required rate scale factor
has been entered, press
)
to return to the
5CALE
.
r
prompt in the configuration menu.
Note:
Adjustment of
5cale
.
R
will disable the
following outputs which must be re-enabled
after the adjustment is complete:
Optional Pulse output
Optional Alarm outputs.
Optional 4/20mA output.
6.14 Timebase:
t-bA5E
The timebase multiplies the rate display by 1, 60 or
3,600 depending upon whether the BA367NE
Counter is required to display rate per second, per
minute or per hour. See Fig 10.
To check or change the timebase, select
t-bA5E
from the configuration menu and press
(
which will
reveal the current setting. Pressing the
&
or
*
button will scroll through the three options:
tb-1
for pulses / second
tb-60
for pulses / minute
tb-3600
for pulses / hour
When the required multiplier is displayed press
)
to return to the
t-bA5E
prompt in the configuration
menu.
6.15 Display filter:
FiLtEr
The digital display filter has two independent
adjustable parameters enabling the rate display
response to be tailored for optimum performance.
The filter parameters are controlled by a two digit
number. The first digit defines the amount of filtering
applied to the display as shown below.
