Data Log Parameters
The data log parameters contains the following information.
Totaliser Audits
P1 or P2
When P1-100, P2-100 = 4 (OCM Head) or 5 (OCM Flow)
P1-460 to 479, P2-460 to 479 Total Audits
The Ultra Twin can give independent Totaliser Audits for each point of
measurement when the Mode, (P1-100 or P2-100), selected is OCM Head
or Flow. Parameters P1-460, P2-460 to P1-479, P2-479 show the date and
daily flow total for the last ten days, the first on the list are the most recent
and last ones are the oldest. When all ten total audits are full the oldest is
pushed out and all totals increment through to allow the new days total to be
registered in the first days total audit parameter allocation.
Important Information
In order to ensure the accuracy of Flow during a 24 hour period, ensure that
the Time P*932 is set correctly. And if required, enable Daylight Saving
for the appropriate time difference P*970 – P*979.
P1-480, P2-480 Clear Logs
This parameter enables all of the Total Audits (P1-460 to 479, P2-460 to
479) to be cleared to factory default values.
Temperature
P1 or P2
The following parameters give information on temperature conditions, for
each point of measurement, as seen by the Temperature source (P1-852,
P2-852) in ºC. All of these parameters are read only and cannot be changed,
though if P1-852, P2-852 are changed they will be reset.
P1-580, P2-580 Minimum Temperature
This parameter displays the minimum temperature recorded.
P1-581, P2-581 Minimum Temperature Date
This parameter displays the date when the minimum temperature was
recorded.
