2.7 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 flow. The figures displayed may have a
preceding sign.
• Such factory setting of current and pulse outputs may lead to measuring errors, particularly
when volumes are metered and totalized.
• If e.g. 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, Section 5.3
- display Fct. 1.04, Section 5.5
- current output I Fct. 1.05, Section 5.6
- pulse output P Fct. 1.06, Section 5.7
• For special applications, such as pulsating flows, see Sections 6.5 to 6.10
