BEKA BA564G, Manual, Page: 10 / 38

5.0 CONFIGURATION & CALIBRATION
The BA564G 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 BA564G Counters are supplied calibrated as
requested at the time of ordering. If calibration is not
requested, Counters will have factory 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 BA564G
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 BA564G uses ‘real’ decimal points. Moving the
position of a decimal point in a scale factor will
affect the instrument calibration.
