Part A System installation and start-up Sect. 2.72.7 Standard factory settings• All operating data are set at the factory in accordance with the specifications contained in theorder.• If no specifications are made in the order, instruments will be delivered with the standardparameters and functions indicated in the table below.• To facilitate the start-up of the instrument, current and pulse outputs are set to handlemeasurements in ”two flow directions” so that the current flow rates and volumes are displayedand/or counted independent of the direction of flow. The figures displayed may have apreceding sign.• Such factory setting of current and pulse outputs may lead to measuring errors, particularlywhen 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 thefollowing 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 6.10Standard factory settingsFct.
