Factory settings 3.2
All operating data are factory set according to your order specifications.
If you have not made any particular specifications at the time of ordering, the instruments will be
delivered with the standard parameters and functions listed in the Table below.
To facilitate easy and rapid initial start-up, current output and pulse output are set to process flow
measurement in “2 flow directions”, so that the current flowrate is displayed and the volumetric
flow counted independent of the flow direction. On instruments equipped with a display,
measured values may possibly be shown with a “ – ” sign.
This factory setting for the current and pulse outputs may possibly lead to measuring errors,
particularly in the case of volume flow counting:
for example, if pumps are switched off and a “backflow” occurs which is not within the range of
the low-flow cutoff (SMU), or if separate displays and counts are required for both flow directions.
To avoid faulty measurements, therefore, it may be necessary to change the factory setting of
some or all of the following functions:
–
low-flow cutoff SMU, Fct. 1.03, Sect. 5.3
– current output I, Fct. 1.05, Sect. 5.6
– pulse output P, Fct. 1.06, Sect. 5.7
– display (option), Fct. 1.04, Sect. 5.4

Display versions:
IFC 010 _ / D, operation: refer to Sect. 4 and 5.
Basic versions: IFC 010 _ / B, operation: refer to Sect. 6.1.
