Standard factory settings
All operating data are set at the factory in accordance with the specifications contained in the order.
If no specifications are made in the order, instruments will be delivered with the standard parameters and functions indicated in
the table below.
To facilitate the start-up of the instrument, current and pulse outputs are set to handle measurements in “two flow directions” so
that the current flow rates and volumes are displayed and/or counted independent of the direction of the flow. The figures
displayed may have a preceding sign.
Such factory settings of current and pulse outputs may lead to measuring errors, particularly when volumes are metered and
totalized, for example if pumps are switched off and “backflows” occur which are not within the low-flow cutoff (SMU) range,
or if separate displays and counts are required for both flow directions.
To avoid faulty measurements, it may therefore be necessary to change the setting of the following functions:
-
SMU low-flow cutoff
Fct. 1.03.
-
display
Fct. 1.04.
-
current output I
Fct. 1.05.
-
pulse output P
Fct. 1.06.
