ix — Full Scale (
FS
)
The setting for Full Scale defines the rate value for which the analogue output will be at maximum
(5V or 20mA depending on option originally ordered).
When all parameters have been programmed it is possible to step through all settings by repeatedly
pressing the centre right hand button (
FUNC
). When all parameters are set to their required values
then the unit can be switched to normal operating mode by pressing the top right hand button (
RUN/
SET
).
Operating Mode
When the instrument is switched from
SET
mode to
RUN
mode or when power is applied after the
programmable parameters have been previously set, the display will show
RATE
for a period of one
second followed by the calculated value or
NO SIG
if the input signal does not change state during
the one second gating period. If the calculated value is too large to be displayed then the display will
read
HIGH
.
If the
FUNC
button is pressed the mode will change from rate display to total display. The unit will
display
TOTAL
for one second followed by the current total count.
Note:
RATE
is displayed using a maximum of six digits.
TOTAL
is displayed using up to the full seven digits.
The rate is continuously monitored and alarms will be set if appropriate. If the analogue output option
has been specified then it will be updated in response to changing rates, irrespective of whether
RATE
or
TOTAL
is shown on the display.
Reset of Total Count
It is possible to reset the
TOTAL
count by either one of two methods.
1.
By momentarily connecting
RESET
(terminal 6 on the Rear Panel) to 0V. This can be
accomplished by a push button switch or by using a key switch which would provide security
and avoid inadvertent or unauthorised operation.
2.
Alternatively, the
FUNC
switch can be used to reset the count. To zero the
TOTAL
display using the
FUNC
switch, the button must be held down for approximately six seconds
while the display shows
TOTAL

When the display shows

TOTAL
count
value will now be displayed as
