8.1.2 Supercal 531
8.1.2.1 Checking of date and time
The correct setting of date and time is important so that the recorded data of the Supercal 531 can
be allocated chronologically.
They can be set with the service software Prog531 over the optical interface.
8.1.2.2 Flow check
If the pulse factor of the flow sensor has been adjusted correctly to the Supercal 531, an existing
flow will immediately be displayed (see flow indicator, point 5.1, page 21).
8.1.2.3 Checking of temperatures
If the temperature sensors are installed correctly in the heating system and connected properly to
the Supercal 531, the displayed temperatures will correspond to the expected system data:
Here, „temperature high“ should be above „temperature low“, and the temperature difference
should be positive (see main menu, point 7.2, as from page 34).
8.2 Applications
8.2.1 Flow calculation
The parameters relevant for the calculation of the flow (precision of measurement, minimum and
maximum holding time, see also 3.4, page 16) are set in our factory. On request, authorized labo-
ratories may carry out alterations over the software Prog531.
The calculation of flow is based on three parameters:
 Precision of measurement of the flow sensor in % or the number of pulses necessary for a new
calculation.
 Maximum holding time between two pulses in seconds
 Minimum holding time (battery operation / mains operation) in seconds
A new flow calculation is carried out if:
a) The defined minimum holding time between the readouts is exceeded and the measured num-
ber of volume pulses is sufficient to reach the desired accuracy.
b) The desired accuracy was achieved by a sufficient number of volume pulses within the mini-
mum and maximum holding time.
c) The defined maximum holding time expired but the number of volume pulses measured is not
sufficient.
In this case however, the flow value will not reach the desired accuracy since the precision ex-
tremely depends on the number of pulses measured.
