5.0 CONFIGURATION & CALIBRATION
The BA568E Counter is configured and calibrated
via four front panel push buttons. All the
configuration functions are contained in an easy to
use intuitive menu that is shown diagrammatically in
Fig 7.
Each menu function is summarised in section 5.3 of
this manual and each summary includes a reference
to more detailed information.
The isolated pulse output, including configuration, is
described in section 6 of this manual. When factory
fitted optional alarms and the optional 4/20mA output
are included, additional functions appear in the
configuration menu which are described in section 9
of this manual.
All new BA568E Counters are supplied calibrated as
requested at the time of ordering. If calibration is not
requested, Counters will have default configuration
as shown in the following table, but can easily be re-
configured on-site.

Note: While the instrument is being configured
counting continues so that any input pulses
occurring during this time are recorded.
5.1 Calibration structure
Fig 6 shows the calibration structure of the BA568E
Counter. The two pulse inputs are processed by the
count function to produce a single output having the
selected arithmetic function, such as the sum of
pulse input A and pulse input b. This output is
passed to the
5cALE . r
and
5CALE . T
functions
allowing the rate and total displays to have different
engineering units.
5CALE . t
is a dividing factor that converts the output
from the Counter function into the required total
display in engineering units. e.g. if the output from
the Counter function is two pulses per pump stroke
and a total display of thousands of pump strokes is
required,
5CALE . t
should be set to 2000.
5CALE . r
is a dividing factor that converts the output
from the Counter function into a rate display with the
required engineering units. e.g. if the output from
the Counter function is two pulses per pump stroke
and it is required to display the pump stroke rate,
5CALE . r
should be set to 2.
The timebase
t-bA5E
is a multiplying factor that
determines if the instrument displays rate per
second, per minute or per hour.
The BA568E uses ‘real’ decimal points. Moving the
position of a decimal point in a scale factor will affect
the instrument calibration.
