MULTICAL

403 registers minimum and maximum flow and power on both monthly and yearly basis. The registration
can be read in full via data communication. Furthermore, the two latest yearly registrations and the latest 12
monthly registrations can be read in ”USER loop”. It depends on the selected display code (DDD-code) whether these
registrations are displayed in ”USER loop”. Read more about the DDD-code in paragraph 3.2.4.
The current minimum and maximum registration for the present year and month can be displayed. In addition
historical data, i.e. minimum and maximum values registered for previous year and months can be displayed. The
dates when minimum or maximum values appeared are displayed in format 20YY.MM.DD. Through serial reading the
time (hh.mm.ss) can be included too. Below you see the complete overview of the registers.
Note: Historical readings (logging values) are not part of ”TECH loop”. They are only displayed in ”USER loop”, and
only if the DDD-code in question includes these readings.
