6.24.6 Source of output pulse:
5ourCE
The output pulse may be derived from:
5CALEd
Incrementation of least significant
digit of the total display. May be
divided and width defined by the
diVidE
and
durAtion
functions to
generate the required output pulse.
dirECt
Output is synchronous duplicate of
the Rate Totaliser input pulse.
Using the
&
or
*
push button select
5ourCE
in the
pulse output sub-menu and press
(
to reveal the
existing pulse source. The function can be changed
by pressing the
&
or
*
push button followed by
the
)
button to return to
5ourCE
prompt in the sub-
menu.
6.24.7 Divide output pulse frequency:
diVidE
When
5CALEd
is selected in the
5ource
sub-function
(6.24.6) the output pulse is derived from
incrementation of the least significant digit of the
total display divided by one of the following five
factors to produce the output pulse:
1
10
100
1000
10000
Using the
&
or
*
push button select
diVidE
in the
pulse output sub-menu and press
(
which will
reveal the existing divisor. The selected divisor can
be changed by pressing the
&
or
*
push button
followed by the
)
button to return to
diVidE
prompt
in the sub-menu.
Note: This function only appears in the pulse
output sub-menu when the
5CALEd
is selected in the
5ource
sub-function (6.24.6).
6.24.8 Output pulse width: durAtion
When
5CALEd
is selected in the
5ource
sub-function
(6.24.6) the output pulse width is defined by this
function. One of following millisecond pulse widths
may be selected:
0.. 1
0.. 5
1
2.. 5
5
10
25
50
100
250
500
Using the
&
or
*
push button select
durAtion
in
the pulse output sub-menu and press
(
which will
reveal the existing pulse duration. The value can
be changed by pressing the
&
or
*
push button
to select the required value followed by the
)
button to return to
durAtion
prompt in the sub-
menu.
Note: This function only appears in the pulse
output sub-menu when
5CALEd
is selected in the
5ource
sub-function (6.24.6).
6.24.9 Pulse storage
If the
diVidE
and
durAtion
functions are
configured such that the output pulse frequency
with the specified pulse width can not be output in
real time, the number of pulses will be stored and
transmitted at the maximum possible speed.
When the total display is reset to zero or the power
supply to the Rate Totaliser is disconnected or
turned off, any stored pulses will not be retained.
